Steel grades

(OP)

Morning all,

I would like to purchase gears from En36 steel.

Various companies have quoted these steels, stating that these are equivalents.

SAE8620
12CrNi13
20CRMNTI

Can anyone advise:
1. Are they an equivalent?
2. What the differences in chemical composition mean in terms of using these steels for gears?

Thanks

Colin

RE: Steel grades

EN36 is 15NiCr13. SAE8620 is 16MnCr5 and like 20CrMnTi is does not contain (enough) nickel to be equivalent to EN36. 12CrNi13 seems at least to be close.
