CARBON STEEL GRADES, Continued
Hot Roll A 1011 HSLAS Grade 50 Class 1 Cold Roll A 1008 HSLAS Grade 50 Class 1
This specification covers high-strength, low alloy hot rolled sheets or cold rolled sheets in either cut lengths or coils. The addition of alloying elements raises the yield point offering higher strength-to-weight ratios.
This material is bendable but requires larger radius. The A1011 HSLAS Grade 50, Class 1 specification covers two classes and five grades in addition to Grade 50.
