Dear,
It is my first question in this Forum, we are saw pipe manufacture and for expander machine we require to develop different size of tools for respective size of pipe, our technical people are asking me to use 40cr10 material for these types of tool. I do not have much more information about this material so please if any body have any idea about it then reply for following queries.

What is 40Cr10 Material? Is it tool steel, Die steel or low alloy steel? Which heat treatment is good for this type of material?

40Cr10 is Romanian standard. its American equivalent is 5140 and material number is 1.7035

in key to steel book it is categorized as Structural and constructional steels.

the heat treatment depends on what you expect from this material.

hope it helps.
