316 Stainless Steel Characteristics: Austenitic stainless steel, due to the addition of metal Mo, its corrosion resistance, high temperature strength is excellent, no magnetism.
316L Stainless Steel Characteristics: Low carbon steel of 316, excellent corrosion resistance, can be used in more severe corrosion conditions.
316 Stainless Steel application:
As a kind of steel with good corrosion resistance, it is suitable for food. Paper, fuel, oxalic acid and fertilizer production equipment, and widely used in petrochemical, nuclear reactor, coastal facilities and other fields.
316L Stainless Steel application:
Because of its excellent intergranular corrosion resistance, it is widely used in the environment of corrosion factors, and it is used to manufacture mechanical components which cannot be heat-treated after the relatively harsh cutting of the environment.
