ISO ISO 15

Profile

This page is mainly introduced the ISO 15 chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of ISO 15,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.
