Product Description
ASTM A36 DIN S235JR GB Q235B Hot Forged/Rolled Carbon Structural Steel Round Bar
1: ASTM A36 Steel Introduction
A36 is a mild steel. It has a final tensile strength of 58 and a yield tensile strength of 36. A36 is relatively ductile and can be stretched to about 20% of its original length during tensile testing. Its ductility and strength also give it good impact strength at room temperature.
