Can a 52100 be case hardened?
Case-hardened steels exhibit higher fracture toughness than through-hardened steel (52100). Generally speaking, it is believed that a 52100 through-hardened bearing life factor would be between 3 – 4.5, based on using either an air melt or vacuum processed melting practices on 52100 steel.

What type of metal is 52100?
carbon chromium alloy steel
52100 steel is a high carbon chromium alloy steel that has a density of 7.81 g/cm3 (0.282 lb/in3). It can be hardened via cold and hot working processes and responds to annealing and tempering and can be strengthened using the heat treatment process.
What is the composition of 52100 steel?
52100 is a relatively simple steel with 1% carbon and 1.5% chromium, and small amounts of Mn and Si. 52100 steel has been in use since at least 1905 [1]. It was developed for use in bearings.
Is 52100 a low alloy steel?
52100 is a high carbon low alloy steel with good strength melted as AOD + VAR or VIM + VAR melt type. It has excellent rolling fatigue strength at temperatures up to 400oF. This grade also possessed good machinability in the annealed condition prior to final heat treatment.
What determines steel hardness?
The hardness of a metal is determined by its resistance to deformation, indentation, or scratching.

What is the hardness of material?
Hardness is the resistance of a material to localised plastic deformation. Hardness ranges from super hard materials such as diamond, boron-carbide to other ceramics and hard metals to soft metals and down to plastics and soft tissues.
