0Cr18Ni9Cu3 stainless steel
Material Name: Stainless steel rod
Grade: 0Cr18Ni9Cu3
Standard: GB / T 1220-1992
● 0Cr18Ni9Cu3 Features and Scope:
0Cr18Ni9Cu3 stainless steel in grades 0Cr19Ni9 adding Cu, to improve cold resistance of steel. 0Cr18Ni9Cu3 corrosion resistance of steel and 0Cr18Ni9 similar. In the wet steam, salt spray and marine atmosphere were very good rust resistance; in acidic medium, the corrosion resistance to nitric acid oxidation, the corrosion resistance in reducing acid bad, but better than 0Cr18Ni9. Cold heading with.
