Product Details

 
Product:BT1004 16mn Gcr15 SAE52100 100Cr6 Suj2 Cold Drawn Seamless Alloy Steel Tube 
 
Bearing steel has a high smelting quality requirements, meanwhile, and requires strict control of sulfur, phosphorus, hydrogen content, and non-metallic inclusions and carbides of the number, size and distribution, non-metallic inclusions and carbides as the number, size and distribution service life of the bearing steel great influence, often bearing failure is in large carbide inclusions or micro-cracks generated around the extension to.
 

Forging of A295 52100 Bearing Steel
AISI 52100 alloy steel is forged at 927 to 1205°C, and should not be forged below 925ºC. A post-forge equalization treatment is recommended at 745ºC for 4-6 hours followed by air cooling for SAE/AISI 52100 steel.
