ALZ 409Ni is a ferritic stainless steel with approximately 11% CR. It belongs to the family of lowest alloyed stainless steels. The chromium content has been chosen to be on the threshold of formation of the passivation layer. It has an oxidation and corrosion resistance that is much better than that of mild steel, but cannot be compared with the corrosion resistance of austenitic stainless steel. This datasheet provides information on composition, physical properties, and elasticity. Filing Code: SS-834. Producer or source: ALZ nv.
