GCr15/100Cr6/SUJ2/SKF3/SKF3S/GCr15SiMn Seamless Stainless Bearing Steel Tube Diameter 8mm ~ 101.6mm
Description
1. GB/T 18254 GCr15SiMn main features and application
GB/T 18254 GCr15SiMn is a kind of high-carbon chromium bearing steel. Compared with GCr15 steel,it contains higher percent of Si,Mn element,which improves the hardenability and elastic limit. Besides, abrasion performance is better than GCr15. But GCr15SiMn is sensitive to the white dot, temper brittleness,plastic deformation in cold working.
GB/T 18254 GCr15SiMn is usually used to manufacture bearing ring,steel ball,cone roller,spherical roller in big size. The bearing parts works at temperature lower than 180°C. Besides,GCr15SiMn can also be used for parts that high hardness and abrasive resistance are required, such as abrasives,measuring tools,taps.

Generally, in china, we usually use fully-hardenability heat treatment,that is,entire inductive heating-surface quenching heat treatment, to make the surface of the material high hardness and abrasive resistance of fully quenching high-carbon chromium bearing steel,and to make the core high toughness and good impact propriety.
Applications
1,Mainly used for manufacturing ordinary rolling bearing ring.
2,other applications such as used for automotive industry and bearings in rotating machinery.
