On April 11,2013, The American Society for Testing and Materials (ASTM) announced a new specification, A1085, impacting the production of steel Hollow Structural Sections (HSS). This new specification provides for enhanced performance to make designing with HSS easier and more efficient for structural engineers.
Some of the benefits of the new specification include:
- Tighter material tolerances and a single minimum yield stress of 50 ksi
- Maximum specified yield stress of 70 ksi
- Standard requirement for Charpy V-notch toughness
- Corner radius range
