Stainless steel refers to steels resistant to weak corrosive media such as air, steam, and water, and chemically etched media such as acids, alkalis, and salts, also known as stainless acid-resistant steels. In practical applications, steels that are resistant to weak corrosive media are often referred to as stainless steels, and steels that are resistant to chemical corrosion are known as acid-resistant steels. Because of the difference in chemical composition between the two, the former is not necessarily resistant to chemical media corrosion, while the latter is generally non-rust. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel.
Stainless steel is usually divided into matrix structures:
1, ferritic stainless steel. Chrome contains 12% to 30%. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its resistance to chloride stress corrosion is superior to other types of stainless steel.
2, austenitic stainless steel. Chromium is more than 18%, also contains about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good overall performance, resistant to many media corrosion.
3, austenitic - ferritic duplex stainless steel. It combines the advantages of austenitic and ferritic stainless steels and has superplasticity.
4, martensitic stainless steel. High strength but poor plasticity and weldability.
Stainless steel does not produce corrosion, pitting, rust, or wear. Stainless steel is also one of the strongest materials in construction metal materials. Because stainless steel has good corrosion resistance, it can make structural components permanently maintain the integrity of the engineering design. Chromium-containing stainless steel also combines mechanical strength and high extensibility, making it easy to manufacture parts that meet the needs of architects and structural designers.
