ASTM A1085
A relatively recent HSS specification, ASTM A1085 was introduced to cover structural applications requiring a minimum yield strength of 50 ksi. Bull Moose meets A1085 with products in round, square, and rectangular configurations.
The ASTM A1085 spec also provides enhanced performance for seismic and other related fatigue-suppressing applications. Due to tighter tolerances, ASTM A1085 allows for FULL Structural Design Capacity of the profile, allowing the structural engineer to reduce welding requirements, lowering fabrication cost and increasing fabrication productivity.
When A500 Isn’t Up to the Task
ASTM A1085 stands as a significantly more stringent standard than A500. One key differentiator is that this spec (unlike A500) mandates Charpy V-notch testing achieving a minimum of 25 foot-pounds at 40 degrees (F), ensuring that the A1085 material is well suited for projects demanding a robust material. The strength of A1085 is also reflected in the spec’s 50ksi minimum yield stress rating, which is particularly relevant for seismic building designs. This rating applies to all HSS shaped, as opposed to A500, which only provides 42 ksi for rounds, and 46 for squares and rectangles. Overall, the A1085 material is also produced to tighter tolerances than A500. For example, allowable wall tolerance is half that of A500–enabling capacity designs to be based on the full nominal wall thickness, rather than on a reduced calculation. A500 is perfect for a broad range of applications…but when the demands are higher, it becomes a job for Bull Moose A1085 material.

Stratusteel™ hollow steel tubing from Bull Moose is stronger than steel, and lighter than aluminum configured to bear the same load. As a result, you can reduce the weight of your design by as much as 35% while getting the strength and other benefits of steel. With Stratusteel, your designs will be dramatically lighter, stronger, and more efficient!
Introduction
Welding of Stratusteel will be different than typical A500 50MY – 80MY tubing. Stratusteel is greater than or equal to 100MY, and as a result, welding requirements are slightly different. When welded properly, Stratusteel will ensure long-lasting performance while making your designs lighter, stronger and more efficient to manufacture.
1. Preparation
All well-established methods or processes of preparation can be used with Stratusteel. However, attention should be paid to any potential buildup of materials on the surface of weld joint, such as thin oxides films from thermal cutting. Make sure all joints are well cleaned prior to welding. If using a plasma cutting for joint preparation, oxygen should be used to minimize risk of porosity in the weld material during welding. It is also possible to use a grinding method, which would remove the risk of porosity in the weld material. It’s recommended to grind down by at least 0.2mm if using this method post plasma cutting.
2. Welding
All common fusion welding methods can be used for welding Stratusteel, such as:
- MAG/MIG – Welding
- MMA-Welding
- TIG-Welding
- Plasma Welding
- Submerged Arc Welding
- Laser Welding
While other methods can be used, these are the most common for Stratusteel. Of these, MAG/MIG welding is the most commonly used welding technique known today. When T-joint welds are close to the edge with a thickness ≥ 8 mm, there should be no sharp defects at the edge. Such defects can lead to stresses in the thickness direction, which can lead to cracking during welding. These welds should be avoided. Shearing is not expected in the use of Stratusteel due to its shape and size. However, if shearing is used, welding should not occur near the sheared area, as it gives increases in stress at the shear location (which can lead to cracking at the weld location in contact with the shear location). It’s recommended that if the location must be used, that it’s thermally cut instead of sheared.
3. Recommended Welding Materials for Stratusteel

| EN 16834(-A) 69X |
Table #1: Recommended weld wire for Stratusteel
4. Preheat and Inter-pass Temperature Considerations
Multi-pass welding may cause the temperature in the welded joint to rise to a level that causes the strength to drop. This is most critical for welds below 500mm, because the temperature will drop between weld bead formations. The maximum inter-pass temperature for Stratusteel is 100 degrees C. For short welds, it is recommended to allow the temperature to cool to 150 degrees C prior to starting the next weld bead. For best results, it is recommended for Stratusteel to be at standard room temperature (temp ≥ 23 degrees C ≤100 degrees C) prior to welding.
5. Hydrogen Cracking Risks
This risk of hydrogen cracking is very low; however, it can occur under very specific conditions. Hydrogen cracking will occur if European Standard 1011-2 is met, whereby a very high hydrogen content > 15 ml/100g of weld metal material and an extremely low heat input of < 0.5Kj/mm are applied, with a combined thickness of 30mm of Stratusteel. These conditions are very rare— however, it is critical to monitor and prevent these conditions in order avoid risk of hydrogen cracking during welding. To avoid this risk, it’s recommend that you use weld materials with low hydrogen content ≤ 10 ml/100g weld metal. When welding Stratusteel it’s important to also follow good general welding practice to avoid increased risk of hydrogen cracking. Rules of thumb to follow to minimize hydrogen cracking are:
| Minimize the hydrogen content in and around the prepared joint. |
Minimize the stresses in the weld join. |
| Use the correct pre-heat and inter pass temperatures. |
Do not use welding consumables of a higher strength than is necessary. |
| Use welding consumables with low hydrogen content. |
Arrange the weld sequence so that the residual stresses are reduced during the welding process along the weld seem nor in the welded joints. |
| Keep impurities out of the weld area. | Set the gap in the joint to a maximum of 3mm. |
Table #2: Rules of thumb for handling prior to welding
6. Heat Affected Zone (HAZ) or Soft Zones When using Stratusteel, soft zones can form in the HAZ. This can happen as a result of changes in the microstructure during welding. However, if normal heat inputs are used, then these soft zones typically do not influence the strength of the weld. For example, if an inter-pass temperature of 150 degrees C is maintained using a single pass, then the heat input which would affect Stratusteel could be increased by 10 – 15% for a butt weld, and approximately 40 – 50% for a filet weld. Following the inter-pass temperature limits will reduce if not eliminate any impact in HAZ leading to soft zones.
7. Direction and Passes for Welding When using Stratusteel we recommend that you start your weld bead in the larger section of the parent material and then work towards the joint. For two pass welds we recommend that once at the joint, the welder restart from the larger section going into the joint (as opposed to returning from the joint to larger section). Please see figure #1 as a representation of starting welds at joint locations.
Restarting second pass welds in the larger parent material allows for inter pass cooling and reduction of stresses at the joint. If welding a plate, it is recommended that the plate use a notch of at least 1” in radius at the joint to prevent concentration of stresses at the joint an follow the inter pass recommendations above.

| Weld Wire Size: .035 weld wire |

8. Fabrication Considerations When fabricating (welding) Stratusteel HSS, consideration should be taken to reduce the residual stresses imparted into the HSS from the shop/field welding process. The weld seam on the HSS should be oriented, if possible, where thermal stresses will not affect the weld seam. For example, orienting the HSS weld seam in a restrained position under a reinforcement plate, bracket, etc., to minimize buildup of residual stresses. Cutouts and holes, where possible, should be placed away from or opposite the weld seam face.
9. Final Considerations All steps mentioned above should be taken when welding Stratusteel. In addition, you should make every effort to have a clean, moisture-free weld area for best results. Condensation, dirt, and any other foreign material should be removed prior to welding. Always monitor and prevent conditions that could cause hydrogen cracking.

HSS Section Properties/ Rectangles
Document Text:
This publication presents tables of dimensions and section properties for rectangular Hollow Structural Sections (HSS) produced by Bull Moose Tube Company.
The dimensions, including nominal width, nominal depth, nominal diameter and nominal wall thickness are subject to the permissible variations stipulated in ASTM A500 “Standard Specification for Cold-Formed Welded and Seamless Carbon Steel Structural Tubing in Rounds and Shapes.”
With today’s manufacturing methods, HSS are produced to more precision than in the past. The strip used to produce HSS is now ordered to thicknesses with tighter tolerances. As a result, ERW HSS manufactured to ASTM A500 will often have a wall thickness close to the Specification allowable value.
In a change from past practice, section property data is now based upon the design wall thickness. The design wall thickness, t, for ERW HSS is less than the specified nominal wall thickness. The design wall
thickness for each HSS size is included in the tabulated data.
The section property data based upon the design wall thickness, t, results in variations in the published area data that do not exceed 3.50% of the data based upon the minimum permissible wall thickness stipulated in ASTM A500. This is consistent with the similar section property data published for hot rolled structural shapes and the manufacturing tolerances associated with those products. The section property data for rectangular ERW HSS are based upon outside corner radii equal to 2.0 times the design wall thickness.
These tables contain all HSS sizes produced by Bull Moose Tube Company as well as current capability to produce sizes. Check with our sales department for current availability.
The more universal terms “Hollow Structural Section” and “HSS” are used in this publication to designate rectangular structural steel tubing. These terms replace “structural tubing” and “pipe,” which had
been used previously.

HSS Section Properties/ Squares
Document Text:
This publication presents tables of dimensions and section properties for square Hollow Structural Sections (HSS) produced by Bull Moose Tube Company.
The dimensions, including nominal width, nominal depth, nominal diameter and nominal wall thickness are subject to the permissible variations stipulated in ASTM A500 “Standard Specification for Cold-Formed Welded and Seamless Carbon Steel Structural Tubing in Rounds and Shapes.”
With today’s manufacturing methods, HSS are produced to more precision than in the past. The strip used to produce HSS is now ordered to thicknesses with tighter tolerances. As a result, ERW HSS manufactured to ASTM A500 will often have a wall thickness close to the Specification allowable value.
In a change from past practice, section property data is now based upon the design wall thickness. The design wall thickness, t, for ERW HSS is less than the specified nominal wall thickness. The design wall
thickness for each HSS size is included in the tabulated data.
The section property data based upon the design wall thickness, t, results in variations in the published area data that do not exceed 3.50% of the data based upon the minimum permissible wall thickness stipulated in ASTM A500. This is consistent with the similar section property data published for hot rolled structural shapes and the manufacturing tolerances associated with those products. The section property data for square ERW HSS are based upon outside corner radii equal to 2.0 times the design wall thickness.
These tables contain all HSS sizes produced by Bull Moose Tube Company as well as current capability to produce sizes. Check with our sales department for current availability. The more universal terms “Hollow Structural Section” and “HSS” are used in this publication to designate square structural steel tubing.
These terms replace “structural tubing” and “pipe,” which had been used previously.
