Introduction

GCr15 bearing steel is a kind of high-carbon chromium bearing steel with low alloy content, good performance and the most useful. It has high hardness, uniform good structural properties, good wear resistance and high contact fatigue performance after quenching and tempering. The steel has the characteristics of moderate plasticity, low cutting performance, poor welding performance, high sensitivity to white spots and temper brittleness. GCr15 bearing steel, containing C0.95-1.05, Mn0.25-0.45, Si0.15-0.35, Cr 1.40-1.65.

GCr15SiMn steel is a high-carbon, high-chromium bearing steel, which has higher wear resistance and hardenability than GCr15 steel. The critical quenching diameter in oil is 90~110mm (volume fraction of 50% martensite). After oil quenching at 840°C, tempering at 350°C, and then light quenching, the surface hardness is as high as 1096HV, and the depth of the hardened layer can reach 1mm. In view of the insufficiency of the heat treatment process of the forming roller, the non-martensitic transformation occurs by pre-cooling at the thin edge to produce troostite or sorbite, which enhances toughness, reduces stress, and then quenches as a whole to meet the process requirements.

The ice-cold treatment can improve the dimensional stability of the bearing, or perform martensite graded quenching to stabilize retained austenite and obtain high dimensional stability and higher toughness. This steel is generally not recommended for forging. Generally used after quenching and low temperature tempering.

High Precision bearing (chrome) steel ball

Chrome steel and other metal balls are manufactured using the following processe

Established in 2006, Xi'an Machinery & Engineering Import & Export Co.,Ltd.（XMEC) is the successor to Shaanxi Marine and Engineering Import & Export Co., Ltd., which is specialized in importing & exporting mechanical and electrical products, complete equipment, various kinds of vessels and ships, marine equipment and port machinery, electronic and electric products, instruments and meters, minerals and metals, light industrial products, etc. XMEC also engages in different trading activities such as import and export of techniques and overseas project contracting.
