Introduction

High-carbon chromium bearing steel is a high-carbon alloy steel containing 1.40 to 1.65% chromium. Its characteristics are more uniform and stable structure after heat treatment, high hardness, good uniformity, good wear resistance, high contact fatigue strength, good dimensional stability and corrosion resistance after annealing, good cutting performance, and relatively cheap price. . This steel can meet the bearing requirements under normal working conditions.

High-carbon chromium bearing steel is widely used worldwide. The most commonly used types are GCr15 and GCr15SiMn, which account for about 80% of the total bearing steel in my country. The properties of the two steels are basically the same. However, because the hardenability of GCr15SiMn is better than that of GCr15, GCr15SiMn steel should be used for larger-sized bearing parts. High-carbon chromium bearing steel is widely used in the manufacture of rolling bearing rings and rolling parts.

GCr15 bearing steel is widely used in the manufacture of spindle bearings, railway bearings, engine bearings, machine tool bearings, mining machinery bearings, general machinery bearings, etc.

According to different production processes, steel balls are divided into ground steel balls, forged steel balls and cast steel balls. According to the processing materials, 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 with carbon, chromium, manganese, molybdenum and other metal elements as the main components, which is made by forging, spinning, rolling and casting. metal element. The special-shaped ferroalloy wear-resistant body is the most important part of the crushing industrial mining balls and cement balls. From the perspective of application categories, steel balls can be divided into two categories: wear-resistant steel balls and bearings in the crushing industry. 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 balls. Steel ball is a general term for steel ball, steel segment and special-shaped grinding body. According to the appearance, it can be divided into a round ball (general narrowly defined name), capsule ball, elliptical ball, hollow ball, multi-faceted ball, multiple missing ball (with dimples on the surface), etc.

Metal balls are used mainly in precision ball bearing designs, roller applications and other demanding industrial applications. The surface is fine finished and hardened for a high load capacity.
