Introduction
GCr15 steel is the representative steel of high carbon chromium bearing steel, with good overall performance, high and uniform hardness, high wear resistance and contact fatigue strength, and good hot workability after quenching and tempering. After spheroidizing annealing, although it has good workability, it is sensitive to the formation of white spots.
Throughout the manufacturing process, statistical process control can ensure tolerance accuracy, good surface finish and consistent high quality. It is most widely used in the ball and roller bearing industry and various automotive applications.
Bearing steel balls have a long history of use in the precision bearing industry and service life, and are more widely used. It can be said that most of the rotating places have steel balls, commonly known as steel balls.
Mainly used to manufacture steel balls, rollers and bushings on drive shafts of internal combustion engines, electric locomotives, machine tools, tractors, rolling equipment, drilling machines, railway vehicles and mining machinery.
Steel balls are divided into grinding steel balls, forged steel balls and cast steel balls according to the production process. According to the processing materials, it is divided into bearing steel balls, stainless steel steel balls, carbon steel steel balls, copper bearing steel balls and alloy steel balls.
Among them, the bearing steel ball is an important basic component in the industry, and the alloy steel ball is a spherical shape made by forging, spinning, rolling, and casting with carbon, chromium, manganese, molybdenum and other metal elements as the main components. metal element. Special-shaped ferroalloy wear-resistant body is an important part of crushing industrial mine balls and cement balls.
We mainly produce chrome steel with sizes ranging from 7.9375mm 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.
