GB 12Cr18Mn9Ni5N

Profile

This page is mainly introduced the 12Cr18Mn9Ni5N chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of 12Cr18Mn9Ni5N,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.
GB/T 1220-2007 standard specifies the stainless steel rods order contents, classification, code, size, shape, weight and allowable deviation, technical requirements, test methods, inspection rules, packaging, logo and certificate of quality.This standard applies to the size is not more than 250 mm hot rolled and forged stainless steel rods.The supply and demand both sides talks things over, can also supply the size larger than 250 mm hot rolled and forged stainless steel rods.
