Product Introduction
Stainless Steel Pipes 304
Austenitic stainless steel contains 06Cr19Ni10(304) stainless steel
Classification of austenitic stainless steel: Austenitic - ferrite duplex stainless steel is a stainless steel with about half of the austenitic and ferrite structure. In the case of low C, the Cr content is 18% to 28%, and the Ni content is 3% to 10%. Some steels also contain Mo, Cu, Si, Nb, Ti, N and other alloying elements.
