6. Features: 420/420C stainless steel is martensitic steel with medium to good corrosion resistance and good material strength. It can resist corrosion from alcohol, ammonia, food environment, fresh water, many petroleum products and organic materials, and some weak acid environments, and is suitable for working environments with ordinary requirements for stainless steel.
7. Application: Applicable to various precision machinery, precision stainless steel bearings, automobile distribution valves, natural gas, auto parts, medical equipment, valves, lighters, writing tools, refineries, casters, fishing gear, lamps, electrical, equipment, instruments, meters, transportation vehicles, household appliances. It is mostly used to manufacture parts resistant to corrosion by the atmosphere, water vapor, water and oxidizing acids.
Wulian Yihe 420 stainless steel balls have uniform roundness, fine surface, high finish, stable quality, high corrosion resistance and other advantages (salt spray corrosion test complies with DIN EN 60068-2-11, test Ka, spraying for 8 hours and resting for 4 hours as a cycle, and there is no red rust on the surface after 12 cycles.).
