430 Stainless Steel

By far the most popular of all straight-chromium stainless steels, Type 430 is the general-purpose alloy of the ferritic class. Referred to as “17 Chrome stainless,” this grade offers favorable resistance to mild atmospheric corrosion and oxidizing environments. Its resistance to corrosion can be enhanced and reflectivity improved with bright annealing.

Product Details

Feature of 430 Stainless Steel Coil

430 stainless steel contains a high chromium content. Chromium can chemically react with oxygen in the air, forming a dense layer of chromium oxide (Cr2O3) on the surface, preventing further oxidation reactions. The formed chromium oxide layer has high stability and is not easily destroyed, effectively resisting the erosion of oxygen, water, and other oxidizing agents. 430 stainless steel can effectively resist oxidation corrosion and surface rusting.

430 stainless steel has good corrosion resistance, but in some specific environments, such as high-temperature chloride environments or during welding processes, intergranular corrosion may occur, leading to damage to the material's grain boundaries, reducing its corrosion resistance, and mechanical properties.
