GBT 022Cr17Ni7

Profile

This page is mainly introduced the 022Cr17Ni7 chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of 022Cr17Ni7,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.
This 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.
