Why is stainless steel rusting? When brown rust spots (dot) appear on the surface of stainless steel pipes, people are surprised: "Stainless steel is not rusted, rust is not stainless steel, and steel may be a problem." In fact, this is a one-sided misconception about the lack of understanding of stainless steel. Stainless steel will also rust under certain conditions.
Stainless steel has the ability to resist atmospheric oxidation - that is, rust, and also has the ability to corrode in acids, alkalis, and salts - that is, corrosion resistance. However, its corrosion resistance varies with the chemical composition of the steel itself, the state of protection, the conditions of use, and the type of environmental medium. For example, 304 steel pipe has absolutely excellent rust resistance in a dry and clean atmosphere, but it is moved to the coastal area, and it will soon rust in sea fog containing a lot of salt; while 316 steel pipe will perform. good. Therefore, it is not any kind of stainless steel that is resistant to corrosion and rust in any environment.
Unique features of stainless steel materials:
1. Complete product specifications and various materials;
2. High dimensional accuracy, up to ±0.02mm;
3. Excellent surface quality and good brightness;
4. It has strong corrosion resistance, high tensile strength and fatigue resistance;
5. The chemical composition is stable, the steel is pure, and the inclusion content is low;
Stainless steel wire detail
316 stainless steel wire : 316 stainless steel wire has better corrosion resistance than 304 stainless steel, and has good corrosion resistance in the production process of pulp and paper. Moreover, 316 stainless steel wire is also resistant to erosion by marine and aggressive industrial atmospheres. 316 stainless steel wire has good oxidation resistance. In the range of 800-1575 degrees, it is preferable not to continuously apply 316 stainless steel, but when the 316 stainless steel wire is continuously used outside this temperature range, the stainless steel has good heat resistance.
304 stainless steel wire: has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, no heat treatment hardening phenomenon. Uses: tableware, cabinets, boilers, auto parts, medical equipment, building materials, food industry
