4,Main application:
For making all kinds of bearing ring and rolling element.For example; steel ball roller and ferrule of internal combustion engine, electric motorcycle, automonilrd, tractors,machine tools, rolling mill, boring machine, mining machinery, general machinery,high load and high speed roating mechanical transmission bearing.Except ball bearing and bearing ring, sometimes also ued to make tools, such as pumching die,measuring tool.
5,Characteristic
Belong to a kind of high carbon chromium bearing steel which most widely used with a good performance and less alloy content. High hardenability and good comprehensive performance.Good machinability after spheroidizing annealing.High hardness,uniform organization, good wear resistance,high contact fatigue performance after quenching and tempering.And good hot working performance.
6,Competitive Advantage:
1).Good purity and homogeneity.
2).Good machinability(roughing, grinding and drilling).
3).Good dimensional stability during heat treatment.
4).Excellent preparation for nitriding, both ionic and gaseous, induction hardening to increase the mechanical properties.
5).Competitive price
6).Delivery Condition:Hot rolled,Forged Heat treatment.
7).Fast production leadtime
8).All the material are inspected with 3 times to meet the highly standards.
