How to select material grade from material composition

Can you provide a couple clues? Such as -

What part of the world do you live in - will try to narrow down potential standards (ASTM/EN/JIS/DIN/ISO/SAE)

What is the form of the steel? Is it structural plate, round bar, casting, forging, tube/pipe?

Dear Responder,

I am from India (Pune).We are following IS standards.I am working on reverse engineering project.Steel sample is in form of round bar dia 32 mm & 40 mm in length. If you have data from other standards please comment or provide link.

Thank you for considering on my problem.

Sorry, I was unable to determine your needs - I am not that familiar with IS steel, but I did browse through my copies of ASM Worldwide Guide to Equivalent Irons and Steels and ASTM Handbook of Comparative World Standards, but was unable to locate it.

That's not to say I may have overlooked it, but I spent a fair amount of time digging - but I just cannot spend anymore time - sorry, and good luck.

Thank you for your time and considerations.

What you really need is someone with access to this:

Al - 1.25

Si - 0.76

Su - 0.27

Cr - 0.22

Mn - 0.65

Ni - 0.046

Cu - 0.052

Mo - 0.031

Fe - 96.72

what is the material for above composition

I'll take a look at this when I get to work.

Spectrographic Carbon analysis is not the best approach.

Carbon and sulfur should be analyzed for the record using a combustion method for best results.

I always had Leco Carbon Sulfur analyzers in my labs.

I do not see any results for grain refiners/deoxidizers /microalloys beyond silicon. Did you look?

The best fit that I could find for the chemistry that you provided was Werkstoffe # 1.2714, 56NiCrMoV7. DIN17350 tool steel. This was not perfect match, but its more brother sister to the analysis that you gave than its cousin or nephew. I'll bet that it will heat treat pretty darn close...

To get closer match to the alloying elements, I could only find MUCH LOWER CARBON CONTENT GRADES.

In the interst of nswering your question How to select material grade from composition, here is how I did it: (knowing that it wasn't a US standard alloy grade because I know them and we don't have any 1.8 CR NI 0.60 carbon grades I went to my foreign directory.)

Basic procedure:

Reference book: Stahlschlussel

Get it from: http://asmcommunity.asminternational.org/portal/site/asm/AsmStore/ProductDetails/?vgnextoid=829c41d97d0f8110VgnVCM100000701e010aRCRD

Open (section 17 in my copy)Werkstoff Nummern Verzeichnis

Go down chrome and nickel columns until find grades with both Chrome and Nickel in weight % greater than 1%; Then find grades containing moly greater than 0.20wt %; then look for Carbon greater than 0.50. then fine tune on closest match for chrome nickel from the compliant carbon grades. Write down grade designation and werkstoffe number. Check against analysis originally posted.

I noted that for machining purposes, 1.2708 might be close cousin to consider as well.

I do not know of any comparable US grades.

Do note the presence of Vanadium as an alloying element, not mere grain refiner.

This one is on the house. If you are going to be doing this sort of thing, you really should purchase the requisite books.

Please register on Cr4, its a courteous thing to do.
