Characteristics of the 3 materials (A2)304 stainless steel: good corrosion resistance, bright surface, high strength, long lasting than ordinary steel. (A4) 316 stainless steel: excellent corrosion resistance, especially in the marine environment, industrial exhaust gases and chemical media and other highly corrosive environment performance is particularly good Higher strength and toughness, can withstand greater pressure and impact. High temperature performance, can be used at a high temperature of 1200-1300 degrees. (Zn) surface galvanised steel: zinc plating is a layer of zinc coated on the surface of steel or iron to prevent rust, the dense layer of zinc acts as a protective barrier against corrosive substances, galvanised steel life is usually longer than stainless steel.
