Cost & Feasibility of Metallurgical Analysis
(OP)
I'm a layperson who is in need of some basic information; is it possible to determine what steel has been used in the manufacture of an OEM crankshaft? If so, any idea as to what that would cost?
Thanks in advance and sorry if it's a silly question.

One source mentions
"5140, 4130, and 4340 steel"

So, narrow done the possibilities. If more than one, then only need to test for a few specific alloying characteristics.

I know that everything from nodular iron to E4340 is used; how can I determine what has been used in such an OEM item when the manufacturer won't say?
RE: Cost & Feasibility of Metallurgical Analysis
If you have a spare or the original crankshaft that is out of the engine, you can have the material typed at a Metallurgical Lab for under $200.

What degree of accuracy can this laboratory typing achieve? For example, can it distinguish between say 1045 and 4340? Or is it more general than that? Thanks again.

I wouldn't bother with the spark evaluation. That is more for sorting. What would you do with the incredibly basic information it provides?

Or is it a nice doorstop?
RE: Cost & Feasibility of Metallurgical Analysis
That's been our procedure in the past for identifying foreign metallic material (customers sometimes like to jump to conclusions that every problem is our fault), and so far it's relatively accurate. It'll probably cost in teh $200 range for something that basic.

A much more comprehensive evaluation can be done by IMR Test labs...

One note:
Metallurgical Laboratories do exactly what you ask them, nothing more, nothing less. You must know the right questions to ask to get the answers you want.
