420 stainless steel has certain properties, corrosion resistance, and high hardness. It is the lower type of stainless steel balls and is suitable for working environments with common requirements for stainless steel. 420 stainless steel is 420 "cutting edge" martensitic steel, similar to Brinell high chromium steel, the earliest stainless steel. 420 has certain wear resistance and corrosion resistance, high hardness, and its price is the lowest among stainless steel balls. It is suitable for working environments with common requirements for stainless steel.

420 stainless steel stripis suitable for all types of precision machinery, bearings, electrical appliances, equipment, instruments, meters, transportation vehicles, household appliances, etc. It is mostly used to manufacture parts that are resistant to atmospheric, steam, water and oxidizing acid corrosion.
Used for fluorine-containing plastics with corrosive gases or corrosive plastic molds with added flame retardants.
420 stainless steel stripsare ideal for making high-hardness, wear-resistant knives and blades. 420 stainless steel rods are widely used in industrial processing, metal cutting, woodworking and other fields.
420 stainless steel stripsare particularly suitable for manufacturing mechanical parts, such as bearings, axles, gears, etc., to cope with heavy-load and high-wear working environments.
420 stainless steel stripsare widely used in manufacturing, such as molds, fixtures, templates, etc.
420 stainless steel stripsare used to make blades, tweezers, scissors, etc. in medical devices.
The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
