About A709 Steel
Barely quenching, no temper brittleness. Cold deformation crack-prone high plasticity, usually for bending, welding performance calendar, curved edges and hammer arch and other processing, and exposure to arc welding, gas welding small thickness, shape demanding or complex shape of the workpiece. Cutting of cold drawn annealed or normalized relatively good state, generally used for manufacturing large discontinuity toughness requirements
