ASTM A736 Abstract :
This specification ASTM A736 covers two grades of low-carbon age-hardening alloy steel plates for welded pressure vessels and piping components.The two grades are nickel copper Chromium molybdenum columbium and nickel-copper-manganese-molybdenum-columbium alloy steel.They are A736 Grade A and A736 Grade C The heat treatment procedure for class 1, 2, 3 plates are presented. The steel shall conform to the required chemical compositions. Mechanical property requirements of the steel plates that include tension test requirements and notch-toughness requirements are presented in details.
