ASTM A576 PDF

General Information Principal Design Features steel has a higher 0. It is hardenable by heat treatment, quench and tempering to develop to ksi tensile strength. Applications Used for crankshafts, couplings and cold headed parts. Forming Forming of steel in the annealed condition is readily accomplished. Welding steel is weldable by all of the welding methods. However with its higher carbon content it is important to use both pre-heat at to F and post-heat at to F practice per an approved welding procedure.
