CG Steel offers ASTM A737 HSLA steel plate in Grade B and Grade C for a wide range of customers. The ASTM A737 specification encompasses high-strength low-alloy steel plates designed for use in welded pressure vessels and piping components. This material is specifically tailored for applications in piping and pressure vessels that demand elevated strength and improved toughness. The specification comprises two grades: Grade B and Grade C.
A737 Grade B is characterized by a minimum yield strength of 50 ksi [345 MPa], while A737 Grade C boasts a minimum yield strength of 60 ksi [415 MPa]. The maximum plate thickness is not explicitly specified, as it is determined by the capacity of the chemical composition and heat treatment to meet the required standards.
