ASME SA737 Grade C is a kind of low Carbon, age-hardening, Ni-Cu-Cr-Mo alloy steel plates material used to fabric pressure vessels. SA737 is divided into two grades or levels:SA737 Grade A and SA737 Grade C.
This specification ASME SA737 covers two grades of low-carbon age-hardening alloy steel plates for welded pressure vessels and piping components.
Standard: ASME SA737/SA737M
Dimension range : 3mm -500mm * 1000mm-4000mm * 1000mm-18000mm
