Steel for Elevated Temperatures

[JackNolan]

I am looking for an up to date resource for information regarding the use of structural shapes and plate in elevated temperatures. We design ductwork and other plant equipment that gets as high as 650 deg F.
We have an old US Steel book that has A-36, A-242 and A-588. We need info on A-992 and A572.

Any ideas?

I have just uploaded these days two Mathcad worksheets that give

1) the stress-strain diagram (before strain hardening starts) of any structural steel from room to 600 ºC temperature

2) The following mechanical properties of any structural steel in approximately the same temperature range

Yield stress at the temperature
Ultimate load strength at the temperature
Initial Modulus of Deformation the temperature
Coefficient of thermal expansion at the temperature

Of course just an engineering approximation.

If this is the kind of information you are searching for download it freely from the Civil Engineering folder within

In the named sheets I have added a cautionary entry and a new file till I investigate the stated coefficient of thermal expansion, that seems not right to me. The new entry goes by MSC that seems to me more reasonable.
