Circular Cold Drawn Bearing Steel Tube / Pipes for Machinery ASTM DIN GB / T 18254 GCr4
Quick Detail:
Products: GB/T18254 GCr4 Stainless Bearing Steel Tube
Standard: GB / SKF/ ASTM / DIN / JIS / BS
Size(mm):
OD:8mm ~ 101.6mm
WT:1.0mm ~ 10mm
Length: Fixed(6m,9m,12,24m) or normal length(5-12m)
Description:
GB/T 18254 GCr4 is a kind of high-carbon chromium bearing steel.GCr4 bearing steel is a low hardenability steel with good impact resistance . And also GB/T 18254 GCr4 saves energy and resources(Cr,Mn,Si,Mo).
This material has been used for railcar axle box bearing,changes GCr15SiMn or GCr15 the situation whose use for bearing inner rings. Now the life is one time longer than before. GCr4 is usually for steel balls or running pulley of low loading and simple shape machine shaft.
The equal material of GB/T 18254 GCr4 in different standard.

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.
Competitive Advantage:
Huacheng Pipe Making Company is one of the largest seamless steel pipe manufacturers in China.We’ve passed API 5L,API 5CT, PED, BV, TUV certification and ISO quality system certification.With good quality and competitive price, we believe we could be your reliable supplier.
