Introduction

GCr15 steel is a representative steel of high-carbon chromium bearing steel with good overall performance.the hardness is high and uniform, and the wear resistance and contact fatigue resistance are high, good thermal workability after quenching and tempering. After spheroidizing annealing, it has good workability, but it is sensitive to the formation of white spots.

Throughout the manufacturing process, statistical process control assures tolerance accuracy, fine surface finish and a consistent high quality. are the most widely used in the ball and roller bearing industry and for a variety of automobile applications.

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 balls.

Mainly used in the manufacture of steel balls, rollers and bushings on drive shafts of internal combustion engines, electric locomotives, machine tools, tractors, steel 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 material, it is divided into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls and alloy balls. Among them, the bearing steel ball is an important basic component of the industry, and the alloy steel ball is a spherical shape formed by forging, spinning, rolling and casting with carbon, chromium, manganese, molybdenum and other metal elements as the main added metal elements. Shaped ferroalloy wear-resistant body, it is the most important part of today's crushing industrial mine ball and cement ball.

The post-processing process of steel ball production, namely, automatic steel ball cleaning, automatic appearance inspection (automatically reject unqualified products), automatic rust prevention, counting and packaging, are all key to the quality of steel balls. Visual inspection of steel balls is an indispensable process in the processing of steel balls. The visual inspection of the steel ball mainly includes the inspection of surface scratches, rust and surface spots. Steel ball production process: stamping, flat grinding, quenching, hard grinding, appearance inspection, fine grinding, cleaning, rust prevention, finished product packaging.

We mainly produce chromium steel with a size of 7.9375mm to 82.55mm. The main material is high chromium GCR15 or GCR15SiMn.

Most importantly, we can customize our products to suit various needs of our customers.
