SAE52100/EN31/SUJ2/GCr15 Special Alloy Steel for making axleProduct Description
1,S imilar grade: EN31/SAE52100/GCR15/Suj2/100Cr6/SH152, Surface treatment
Round bar:Black /Grinding /Polished /Peeled /Turned
Steel plate:Black /Milling /Machined3, Characteristic
Belong to akind of high carbon chromium bearing steel which most widely used with agood pLCD Module erformance 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 tePackaging Materials mpering.And good hot working performance.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, Chemical composition(%)CMnSiCrPS0.95-1.050.20-0.400.15-0.351.30-1.65≤ 0.027≤ 0.020
