High-Strength Low-Alloy Structural Steel, up to 50 ksi [345 MPa] Minimum Yield Point, with Atmospheric Corrosion Resistance for welded, riveted, or bolted construction.
Primarily meant for use in welded bridges and buildings where savings in weight or added durability are important.
We will be glad to help you select the exact grade for your needs.
- Strength, Yield Strength ksi (MPa), Tensile Strength ksi (MPa): Strongest, 105-135 (725-930)
- Formability: % Elongation: Basic, 21%
For better formability consider Drawing Steel
- Joining – Fair
Design and welding must account for stresses.
- Corrosion Resistance – Very Good
When properly exposed to the atmosphere, this steel is appropriate for many uses unpainted. (The atmospheric corrosion resistance of this steel in most environments is significantly better than that of carbon structural steels with or without copper addition.)
- Chemistry – Medium carbon, medium manganese, silicon, copper, alloyed with Chromium, and Molybdenum
- Cost – Higher.
Good when thinner or stronger steels will add value.
