STEEL GRADES WHICH DOESNOT REQUIRES TEMPERING

[Zlatan13]

Dear Materials experts,

I would like to request information on steel materials grade which can be hardened (preferably medium carbon steels through Induction hardening route) but doesn't need tempering operation.
Kindly advice any such self tempering grades exists in practice. Few cast Iron grades(FG 200) has been practiced Hardened alone up to my knowledge.

Thanks, in advance.

If you are hardening using induction method, why not do a tempering using flame, i e. a gas torch?

This would help you to procure common steel grades available in the market instead of exotic ones

You could also add an induction tempering step to your recipe to ensure uniform case hardness.

@Dhurjati Sen, the need of the grade is to eliminate already practicing tempering (Continuous belt type) for cost reduction purpose and achieve fine martensite structure in hardening itself, so an alloy which could fulfill this requirements will be handy in eliminating tempering process.

@dbooker630 Thanks for your input, We do have provision in Induction furnace to make tempering as well with modifying receipe, but the motive is to choose alloy which could produce fine martensite during hardening and reduce the cost incurred by tempering.
