material strength of case hardened low carbon steel
material strength of case hardened low carbon steel
(OP)
Can anyone advise if there's a method (other than the destructive test) to find out the difference of the material strength of a case nardened low carbon steel shaft as compare to a non heat treated one.

RE: material strength of case hardened low carbon steel
Thanks for the advise, But I think my earlier was a hasty one, I should have elaborated more specifically that the material strength that I mentioned was actually the allowable bending moment / tensile strength for case gardened shaft and the non hardened one.
RE: material strength of case hardened low carbon steel
I'm considering the bulk property, so if there's an influenze between the case hardened and an non-hardened one, should there any methodology to quantify that?

RE: material strength of case hardened low carbon steel
If you data on any these old steels come back with a number.
1015
1020
1022
1117
1118
or
3310
4320
4620
4820
8620
9310

I need to have comparison between.
C12L14 free cutting steel
1022 low carbon steel
SCr415 Chromium alloy steel
SCM415 Chrome Molydenium alloy steel
Thanks.

To what depth are these steels carburized? What is the ratio of sectional areas for the carburized and non-carburized areas?

RE: material strength of case hardened low carbon steel
I only have information on the steels I listed. Maybe CoryPad or someone might have access to a SAE Handbook or the Japanese equivalent. The SAE & Bethlehem Steel is where my data is form. I don’t have anything approaching the low carbons of the SCr415 or the SCM 415.
