- Apr 08, 2019-

420 stainless steel ball in the process of its functional requirements, the hardness of the product should reach 51-52 degrees, magnetic, there must be 430 stainless steel ball corrosion resistance and resistance, its main use is suitable for each Precision machinery, bearings, electrical 440 stainless steel ball equipment, transportation vehicles, household appliances, etc. It is mostly used to manufacture parts resistant to atmospheric, water vapor, water and oxidizing acids.


420 stainless steel ball use field

420 stainless steel ball is generally used for precision and anti-rust function, suitable for motorcycle parts, pulleys, stainless steel bearings, plastic bearings, crafts, valves, oil.

Characteristics: Representative of martensitic steel, commonly known as stainless iron, magnetic, has good rust prevention function, and high hardness HRC50-55.

The bearing steel ball is one of the important parts in the ball bearing. The quality of the stainless steel ball in the fuel burner part largely affects the dynamic performance and service life of the bearing. The reduction of the bearing vibration value and the improvement of the life are inseparable from the improvement of the surface quality of the bearing steel ball.

The grinding process of the steel ball is undergoing a major innovation in the stainless steel ball for transportation. The traditional cast iron grinding disc is replaced by a resin grinding wheel. The grinding and grinding research is carried out to greatly improve the production efficiency while ensuring that the life of the steel ball is not affected.
