identify steel from composition

identify steel from composition

identify steel from composition

(OP)
Is there a good resource I can use to identify a steel by its chemical composition?  I received an MTR from a vendor who wants to substitute a material, but there's no specification on it (unless "58 x 295" is a designation I'm not familiar with?) and it doesn't look like it matches anything in Jorgensen particularly closely.  I guess what I'm imagining is some sort of dichotomous tree that breaks everything down by specified ranges, and after I enter the percentages of a few additives it's narrowed down to a list of possibilities.

Of course, I've asked the vendor to give me the designation, but while I wait for a response I'm curious to know if this is possible...

Thanks!

RE: identify steel from composition

You can use MatWeb to input chemical compositions and it will return closest matches:

For true identification, you need to compare with published documents like standards (ASTM, ISO, SAE), the ASM Handbook series, or one of the better guides (Stalhschluessel, ASM's Worldwide Equivalents).

"58 x 295" sounds like the dimensions of a plate or sheet.

@JoeTank: Yes, it does.  Not a very big one though, if we're talking mm, or an enormous one if we're talking inches.  Maybe cm?

Anyway, it turns out the material was (CSA G40.21) 50W - it certainly didn't mention that anywhere on the MTR.  Is that common?  I've only glanced at a few in the past, but I don't remember noticing that they didn't include the spec being tested to.
