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
