Stainless steel surface finish, a higher corrosion ductility, toughness and mechanical strength, acid and alkaline gases, solvents and other media. It is a rusty steel is not easy, but not definitely not rust. Stainless steel plate refers to resistance to atmospheric, steam and water and other weak corrosive medium plate, and acid-resistant steel refers to acid, alkali, salt and other chemical etching medium corrosion of steel. Stainless steel since the early 20th century came, and now there are more than one century of history.

Stainless steel plate manufacturing method according to two types of hot and cold, including the thickness of 0.02-4 mm thin cold and 4.5-50 mm plate.

By organizational characteristics of steel divided into five categories: austenitic, austenitic - ferritic, ferritic, martensitic, precipitation hardening.

Requirements can withstand oxalic acid, sulfuric acid - ferric sulfate, nitrate, nitric acid - hydrofluoric acid, sulfuric acid - copper sulfate, phosphoric acid, formic acid, acetic acid and other corrosive, widely used in chemical, food, pharmaceutical, paper, oil, atomic energy, etc. industry and construction, kitchen utensils, cutlery, vehicles, household appliances all kinds of parts.

In order to ensure all kinds of stainless steel yield strength, mechanical properties of tensile strength, elongation and hardness to meet the requirements, it must go through annealing, solution heat treatment, aging heat treatment before delivery plate.
