According to the method of cold and hot points two kinds, including 0.5 4 mm thickness of plates and 4.5-35 mm thick plate.

According to the characteristics of the steel group is divided into five categories: austenitic size, austenitic grain size, iron-iron grain size, shape, markov precipitation sclerosis type.

Requests can withstand oxalic acid, sulfuric acid, nitric acid, nitric acid-ferric sulfate-hydrofluoric acid, sulfuric acid, phosphoric acid, formic acid, copper sulfate, acetic acid, etc. Various kinds of acid corrosion, widely used in chemical industry, food, medicine, paper making, oil, atomic energy industry etc, as well as the construction, kitchen utensils, tableware, vehicles of all kinds of parts, household appliances.

In order to ensure that each kind of stainless steel plate of the yield strength, tensile strength, elongation and hardness of mechanics performance accords with a requirement, steel plate must pass before delivery annealing, solid solution treatment, aging treatment of heat treatment, etc.

Stainless steel plate [1] the surface is bright and clean, have a high plasticity and toughness and mechanical strength, acid and alkaline gas and other media, the solution of the corrosion. It is not an easy to rust of alloy, but not absolutely doesn't rust.

Stainless steel corrosion depends primarily on its alloy composition (chrome, nickel, titanium, silicon, aluminum, etc) and internal organizational structure, plays a main role is chrome elements. Chrome has the very high chemical stability, can in the steel surface passivation membrane formation, the metal and isolated, protect steel plate were not oxidation, enhance the steel corrosion resistance. Passivation membrane destruction, the corrosion resistance will decline.
