Need material information (SOLVED)

[Kunstmaan]

On a old (1950) BOM a part is made from Cast Iron Te32.
The question is where to find the correct data on material composition.

Thanks Berdien

It might help if you can give clues as to where (which country, what industry) the item originated from.

Its actualy a sweidish origin

My Google Fu indicates it's probably an indicator of the amount of the element Tellurium (TE) that is in the mixture of the cast iron.

I have attached this pdf in case this link goes dead:

Thanks for the information

Hi,

as far as I remember / assume that "Te32" is actually "Te 32-92" which is an very old trade name for "white mallable cast iron". In german "Temperguss", thats where the Te comes from, and 32 refers to 320 kg/mm2 tensile strength.

In very old (around 1950 or older) DIN 1692 documentes state that tradename, newer ones do not.
DIN 1692 was replaced by DIN EN 1562 and therefor the new materialname would be EN-GJMW-350-4 (GTW-35-04) and Materiallnumber is EN-JM1010.
With this you should be able to find the corresponding material specifications. But it is basically cast iron that is heat treated.

Is the part in the old bom something like a pipe fitting?

Hope that helps

Stefan

Have a look at the part here: https://www.alibreforum.com/forum/index.php?media/kh03344-38.938/

Yes, a good application for malleable iron.

White cast iron, heat treated to make it non-brittle. Used even now for many automotive parts because it is a "near net shape" process, with minimal machining needed.

Have a look at the part here...

That sure is a typical Casting with "thin walls" that require some "elasticity" which regular grey casting iron does not have.
So I would specify with, using the modern EN-GJMW-350-4.
