Stainless Steel Sheet

- May 25, 2017 -

Two types of hot-rolled and cold-rolled, including sheets having a thickness of 0.5 to 4 mm and a thick plate of 4.5 to 35 mm.

According to the organizational characteristics of steel is divided into five categories: austenitic, austenitic - ferrite, ferrite, martensitic, precipitation hardening type.

It is resistant to various acids such as oxalic acid, sulfuric acid-ferric sulfate, nitric acid, nitric acid-hydrofluoric acid, sulfuric acid-copper sulfate, phosphoric acid, formic acid and acetic acid. It is widely used in chemical, food, medicine, paper, oil and so on. Industrial, as well as construction, kitchen utensils, tableware, vehicles, household appliances all kinds of spare parts. In order to ensure that all kinds of stainless steel yield strength, tensile strength, elongation and hardness and other mechanical properties meet the requirements, steel plate before delivery must be annealed, solution treatment, aging treatment and other heat treatment.

Stainless steel plate surface smooth, with high plasticity, toughness and mechanical strength, acid, alkaline gases, solutions and other media corrosion. It is a kind of stainless steel is not easy to rust, but not absolutely no rust.

The corrosion resistance of stainless steel depends mainly on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal structure, the main role is the chromium element. Chromium has a high chemical stability, can form a passive film on the steel surface, so that the metal and the outside isolation, to protect the steel plate is not oxidized, increase the corrosion resistance of steel plate. After the passivation film is damaged, the corrosion resistance decreases.
