Stainless Steel Bearing

Stainless Steel Bearing

SWC stainless steel ball bearing material

420 stainless steel is a kind of martensitic stainless steel, with certain wear resistance, corrosion resistance and high hardness. It is suitable for all kinds of precision machinery, bearings, electrical equipment, instruments, meters, transportation tools, household appliances, etc. It is mainly used to manufacture parts resistant to atmospheric, water vapor, water and oxidizing acid corrosion.

· SUS440 (9Cr18Mo)

Martensitic stainless steel has higher carbon content than Cr13 steel, so its strength and hardness are higher than Cr13 steel. Other properties are similar to Cr13 steel, but its weldability is poor. It is usually not used as welding material. It is used to make surgical and medical tools. The steel has better high temperature dimensional stability, strong corrosion resistance and toughness. Now it is more widely used in hand knives and high-quality factory knives.

· SUS304 (06Cr19Ni10/0Cr18Ni9)

304 austenitic stainless steel has good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It has good hot working properties such as stamping and bending. It has no heat treatment hardening phenomenon. Because of its good heat resistance, non-magnetic 304 stainless steel is widely used in the production of corrosion-resistant and molding equipment and parts. At present, 304 stainless steel has been widely used in food, chemical industry, atomic energy and other industrial equipment and decoration fields, as well as household products, cabinets, indoor pipelines, water heaters, boilers, bathtubs, auto parts, medical devices, building materials, chemicals, food industry, agriculture, ship parts

· SUS316 (0Cr17Ni12Mo2)

316 austenitic stainless steel has plasticity, toughness, cold denaturizing, good welding process performance, good appearance gloss of cold rolled products; due to the addition of Mo (2-3%), it has excellent corrosion resistance, especially pitting resistance, high temperature strength, excellent work hardening (weak magnetism after processing), non-magnetic solution state, and good welding performance. All standard welding methods can be used for welding.
