316L Stainless Steel Coil 1-4mm China Tfv4 Stainless Steel Coil Factories
The corrosion resistance of austenitic stainless steel comes from the chromium oxide protective layer formed on the metal surface. When the temperature of the material is heated to 450 degrees - 900 degrees, the structure changes, will form chromium carbide along the edge of the crystal and can not form chromium oxide protective layer, thus reducing the corrosion resistance, this is also called "intergranular corrosion". Thus there are 304L and 316L, both of which reduce intergranular corrosion due to their low carbon content.
