ASTM A53 Gr.B is a standard specification for seamless and welded black and hot-dipped galvanized steel pipes used for mechanical and pressure applications. It covers both seamless and welded pipes in NPS 1/8 to NPS 26. The material is intended for use in mechanical and pressure applications such as steam, water, air, and gas lines.
The chemical composition of ASTM A53 Gr.B steel pipe typically includes carbon, manganese, phosphorus, sulfur, and copper. The minimum tensile strength of the material is 60,000 psi and the minimum yield strength is 35,000 psi. The pipes are available in different grades, which are determined by the chemical composition and mechanical properties of the steel.
