434 Stainless Steel annealed sheet, chromium 12%~30%.Its corrosion resistance, toughness and weldability increase with the increase of chromium content. The corrosion resistance of chloride is better than that of other kinds of stainless steel. （18Cr-1Mo） is a modified steel of 430 steel, with a salt tolerance of 430 steel and used for automotive decoration materials.
