ASTM SAE SUJ2 Cold Rolled Thin Bearing Steel Strip for Spring

 

Introduction

SUJ2 bearing steel is a high carbon, chromium containing low alloy steel that is through hardening and noted in particular for use as SPRING.

 

Advantages

  • 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

 

Applications

SUJ2 bearing steel is primarily used for the manufacture of aircraft bearings and other highly stressed parts. It has the good rolling fatigue strength required at operating temperatures less than 400ºF (200ºC). The grade is preferably vacuum arc re-melted to give optimum performance.

HEAT TREATMENT

ANNEALING: SUJ2 bearing steel is annealed at 872°C (1600°F) followed by slowly cooling to reduce cold working or machining stress.

HARDENING: SUJ2 bearing steel is hardened by cold working, or heating and quenching. It can be carburized at 913°C (1675°F) followed by quenching. It is again heated at 788°C (1450°F) followed by quenching for the second time.
