High Carbon Steel Balls HRc61 DIN 5401 Chrome Metal Ball
Profile
GCr15 steel has low alloy content and good performance. It is currently the most widely used bearing steel. It has excellent properties such as uniform structure, high hardness, high wear resistance and contact fatigue strength, and good hot workability after quenching and tempering at low temperature.
From the perspective of application categories, steel balls can be divided into two categories: wear-resistant steel balls in the crushing industry and bearing steel balls in the precision bearing industry.
Bearing steel balls have a long history of use in the precision bearing industry and life, and they are more widely used. It can be said that most of the places where there is rotation, there are steel balls, commonly known as steel balls and steel balls. Steel ball is the general term for steel ball, steel segment and special-shaped grinding body. According to the appearance, it can be divided into round balls (general narrow names), capsule balls, elliptical balls, hollow balls, multi-faceted balls, multiple missing balls (with pits on the surface), etc.
Steel balls are widely used in bearings, hardware, electronics, mechanical equipment, electric power, mining, metallurgy and other fields.
We mainly produce chrome steel with sizes ranging from 1.5mm to 82.55mm. The main material is high chromium GCR15 or GCR15SiMn.
Most importantly, we can customize products to meet the various needs of customers.
Advantage
- Uniform size: Ultra-lapping to ensure that each steel ball has a uniform size.
- High performance: have extremely corrosion resistance after oil, high hardness and higher wear resistance.
- Precision: the steel ball has high precision and accurate tolerance, suitable for many occasions and different accuracy requirements.
- Widely used: high-end industries such as precision bearings, instruments and finishing.
