I got these from Google.

There are 270,000 more results if these don't meet your needs.

Can also try ASM (american society for metals). I haven't used their site for some years, but some searching will reveal what the steel is.

What form is it? cast, forged, pipe, plate, ? There are physical/mechanical properties involved also.

And where is the picture?

Does your steel have a crust on it?

Is it a Corten Steel type that doesn't rust, a solid sheet or sinter construction?

Will it be used for ship building, storage tanks?

What is the hardness, commercial size and thickness?

How did you obtain the spectral emissions?

Did you make a temperature related spectro plot?

Between what ranges and on how many samples?

You seem to work backwards: Normally the steel company names the steel and knows the composition in an attempt to meet your needs.

Is your composition the one you asked the manufacturer to produce?

I've always found this type of CR4 question both amusing an informative of what might follow.

"I do not know what this widget is or if what I do know is enough to identify what I have. Here is the information I do know if I performed the barely specified test properly." <Cryptic data dump attached>

Please, PLEASE! Do not take my comment as a slight on you or anyone about what CR4 can offer to solve a technical problem but from the jargon front loaded collection of information you have provided, I quickly wonder if anyone could discern a false answer from a true answer from the information provided. Particularly with the poor grammar and run on word, let alone sentence verbiage.

[English is a sloppy language that accepts many other conflicting language syntax but a line must be drawn somewhere or gibberish will be accepted as normal. ]

I'll bet e^205j Italian Lire that it is a transcendental number that has yet to be codified as meaningful for a useful mathematical operation. Don't ask me about the difference between precision, tolerance or uncertainty. I meant what I said regardless of the real meaning of imagination.

We get a lot of these types of questions on another forum I'm on... typically they are from draftsmen/designers that work for some company that is trying to reverse-engineer some piece of industrial machinery so they can bring their own design to market.

Yours has!

Pretty sure about that too.

It is ordinary carbon steel, and the Silica being above 0.1 indicates it is not intended for boiler steel.

Normally this sort of information is a little over the top when talking with a steel supplier.

What is the steel being used for and why did you have to go to such lengths, could you not find a specification for it? Why is it soooo critical you match (or is it)?

Oh imagine someone is going to use it for a boiler now. Why going the length of analysing it if they did not want to use it for something important.

Would be far to easy - cost intensive - to buy the correct material.

This one was in the yard . . .

Sure it was, and you never, ever use steel that has just been lying about with no pedigree. That will be the first place she blows!

When your deadline looms larger than your budget, anything can happen.

Or the water is blown out of the boiler. If this find is boiler plate quality, it would truly be a "steal"!

That's why we also sell pressure relief valves.

Would you really want to trust an untested pressure relief valve?

Tested and used are entirely different things.

I would disagree that they are entirely different. They are significantly different and that significance is precisely your point. However, testing anything is a non consuming way things get used. Testing something is a crucial subset of using something. That is not entirely different.

Steam safety valves are meant to never open, but very handy when they do open for the one time they should be open. They are strictly not to be re-used, as after opening under high pressure, they valve itself will most likely lose its pressure calibration, and/or not spring back totally shut after an operation.

They are a safety last ditch device, not a "boiler control valve".
