ASTM A736 Grade C is a kind of low Carbon, age-hardening, Ni-Cu-Cr-Mo alloy steel plates material used to fabric pressure vessels. A736 is divided into two grades or levels:A736 Grade A and A736 Grade C.
This specification ASTM A736 covers two grades of low-carbon age-hardening alloy steel plates for welded pressure vessels and piping components.
Standard: ASTM A736/A736M
Dimension range : 3mm -500mm * 1000mm-4000mm * 1000mm-18000mm
