Product Description

Alloy Steel Machinery Steel SAE52100 100CR6 EN31 SUJ2 GCr15

Product Introduction
Alloy 52100 bearing quality / aircraft quality dual certified steel is a moderately deep hardening alloy having high resistance to wear, medium toughness, and low resistance to softening at high temperatures. It is an oil hardening high Carbon - Chromium alloy that develops high surface hardening.

52100 Premium Quality VAR is 52100 melted twice (vacuum arc remelted) and is used in various bearing applications for aircraft or other critical parts. It has excellent wear and abrasion resistant qualities and can also be used in place of tool steels. It has the same basic properties as 52100 but the VAR melting provides extreme cleanliness.



Features
Superior hardness, 60-67 on Rockwell hardness scale (Rc) at room temperature
High carbon chrome alloy steel
Operates continually at temperatures up to 120°C
Used to produce precision ball bearings and roller bearings
Cost-effective
Long working life
