316L is ultra low carbon austenitic cr-ni-mo stainless steel, the hardness is lower than 304, wear resistance is slightly worse, but the resistance to intergranular corrosion is strong, can be applied to contain a small amount of chlorine ions and other harsh acidic conditions, mainly for the chemical industry, not suitable for civilian products in the occasion, in contact with iron and other processes, surface scratches will cause carburizing, thus rust , affecting the appearance and corrosion resistance.
