Material Composition of 9Cr2Mo

The chemical composition is on its name, Cr-Chromium , Mo -Molybdenum

Like what is your main concern? Strength or Corrosion Resistance or electric properties, Temperature service, we don't know. So we don't know what's the equivalent

Provide more details & application.

Yes I know that the composition is in its name but I want the detailed chemical composition of this material as if I have the details of the composition then I can look in to my data which I have with me of other local metals and find an equivalent material.

The application is to make a specific Ring of Dia 600 mm having 90mm thickness which is to be hardened up to 48-52 HRC and will be used as a Fin in the Roll used for the Pipe manufacturing line.

Thanks for your answer though.

My hands are up, with the materials engineer. I'm not so much into material science, but as far as I know, CrMo, from the name alone suggest an alloy of steel in used in heat service - actually this is typical a stainless steel additive that sometimes it goes along with Nickel & Ti

Material Engineers, go ahead.

Thank you for the answers. But I would like to tell you that this is not a stainless steel family metal it is an Alloy Steel Grade.

9% Chromium, 2% Molybdenum?

Thank you for your answer but that was not the total composition it was only derived from the name itself which I also knew. But finally I found it some where else if any one wants then it is as below.

Carbon(C) - 0.08/0.12

Silicon(Si) - 0.3/0.5

Manganese(Mn) - 0.9/1.2

Chromium(Cr) - 9/10

Molybdenum(Mo) - 1.9/2.1

Vanadium(V) - 0.25/0.35

Niobium(Nb) - 0.35/0.45

Now this is called the detailed composition of any kind of metal.

Thank you once again.

I guess you answered your own question. Now that's a good start. I'm happy for you.
