Achieving hardness on en36

Achieving hardness on en36

Achieving hardness on en36

(OP)
how can we achieve HRC 50 on EN36 of Diameter 40 MM so as it does not become brittle.

RE: Achieving hardness on en36

EN36 is a case hardening steel . Popularly used for gears, sprockets etc. You will not achieve those hardness at the core .

RE: Achieving hardness on en36

Is water quenching appropriate given it's low C? Just curious, not my thread.

RE: Achieving hardness on en36

(OP)
i require case hardening only but the material should not become brittle.

RE: Achieving hardness on en36

I have rarely seen them water quench. It is always oil quenched . It is very unlikely that with a carbon of around 0.15% it is possible to get RC50 in the core(of course it does have about 3.5%Ni and Cr about 0.8%)

If this statement is correct,why did you ask for 50 RC in the core. Your question was misleading

RE: Achieving hardness on en36

Yes, I agree the low C won't ger 50Rc even at fully quenched condition. Very unlikely, maybe 40+ as quenched.

Sorry, wittyrohit I hacked your thread. This steel at QT condition shouldn't be brittle but maynot get 50Rc. But you can get it on surface by carburizing it.
