EN-31
EN-31 Alloy Steel
Application : Automobile Industry,
Construction, Pharmaceutical / Chemical Industry, Oil & Gas Industry
En-31 Alloy Steel is a quality high carbon alloy steel which offers a high degree of hardness with compressive strength and abrasion resistance. Because of high carbon content it has a good strength and used in moulds back plating. It is also called bearing steel.
Equivalent Grades :

Equivalent Grades :
- 100Cr6, AISI SAE E52100, 100Cr6, 2258, 100C6
Chemical Composition% :
Annealing :
Heat uniformly to 800°C, equalise, then furnace cool. (Hardness about 229 Brinell).
Hardening :
Heat uniformly to 800/820°C until heated through. Allow 30 minutes per inch of ruling section and quench immediately in oil.
Stress Relieving :
If machining operations have been heavy or if the tool has an unbalanced section, remove stresses before hardening by heating up to 700°C, equalise, then cool slowly.
Tempering :
Heat uniformly and thoroughly at the selected tempering temperatures and hold for at least one hour per inch of total thickness.
Applications :
Ball and Roller Bearings, Spinning tools, Beading Rolls, Punches and Dies
