This page is mainly introduced the S50400 chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of S50400,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.

Standard Specification for Seamless Ferritic Alloy-Steel Pipe for High-Temperature Service

Alloy steels are designated by AISI four-digit numbers and are more susceptible to heat and mechanical treatments than carbon steels. They comprise different kinds of steels having compositions which exceed the limitations of Va, Cr, Si, Ni, Mo, C and B in the carbon steels.
