Properties for DIN17100 RST42/2
Properties for DIN17100 RST42/2
(OP)
We have 24 process tanks (ø12.8m x 31m high) for which the main construction material for given as DIN 17100 RST 42/2.
They were constructed circa 1980.
We need to do some design recalculations and must have some properties: ideally allowable stress, otherwise Tensile and yield strength.
However, I cannot find any details on this material, apart from one reference on a materials property comparison for pipe and tube. There is no problem finding references to RST44/2.
Could anyone help shed some light on this?
Thanks

Yes, I realise it has been replaced and know that S275JR is acceptable for St 44/2.
But I really need to find the correct allowable stress for my calculations, otherwise I'm stuck with a very low assumed allowable stress.
The real problem I have is that I'm not sure whether this RSt 42/2 grade existed (possibly an error on the drawings?) and if it did where can I find the the yield or tensile stress.

Would anyone have a copy of the 1966 DIN 17100 and be able to scan the page with the mechanical properties for RSt 42-2?
Otherwise I'll see if I can get an old copy of the standard.
Cheers

I've manged to find a copy the 1966 standard.
Out of interest the min. yield was 255MPa.
