Looking for Info on 20CrMoTiH 1

[met1]

I'm looking for info on 20CrMoTiH alloy steel.

It appears to be a chinese alloy.

Is there an AISI equivalent?

What does the H stand for?

The 18th edition of Stahlschluessel references a grade 20CrMnTiH from the Chinese standard GB 5216-85. I have no idea if the Chinese standard has been revised since 1985 to include a new grade 20CrMoTiH. The standard is for structural steels with specified hardenability bands, hence the H in the designation. Composition for 20CrMnTiH is as follows:

C = 0.17-0.23
Si = 0.17-0.37
Mn = 0.80-1.15
P & S = 0.035
Cr = 1.00-1.35
Ni = 0.30 max
Ti = 0.04-0.10
