Stainless steel is generally the general term of stainless steel and acid resistant steel. Stainless steel refers to the steel that is resistant to the corrosion of weak media such as atmosphere, steam and water, while acid resistant steel refers to the steel that is resistant to the corrosion of chemical corrosive media such as acid, alkali and salt.
Stainless steel has a history of more than 100 years from its inception in the early 20th century to 2019. The invention of stainless steel is a major achievement in the history of world metallurgy. The development of stainless steel has laid an important material and technological foundation for the development of modern industry and scientific and technological progress. There are many kinds of stainless steel with different properties. It has gradually formed several categories in the process of development.
According to the performance characteristics and uses of steel, it is divided into nitric acid resistant stainless steel, sulfuric acid resistant stainless steel, pitting corrosion resistant stainless steel, stress corrosion resistant stainless steel, high-strength stainless steel, etc; According to the functional characteristics of steel, it is divided into low-temperature stainless steel, non-magnetic stainless steel, free cutting stainless steel, superplastic stainless steel,
