yield and tensile strength SA 1008 & SA 1011

yield and tensile strength SA 1008 & SA 1011

yield and tensile strength SA 1008 & SA 1011

(OP)
SA 1008 lists yield strength and tensile strengths for commercial steel for temperatures greater than 100 deg. F.

How can I find out what the yield strength and tensile strength are for SA 1008 STRUCTURAL QUALITY steels at a temperature of 350 degreees F.

What about yield strength and tensile strength for SA 1011 STRUCTURAL QUALITY steel at the same temperature?

RE: yield and tensile strength SA 1008 & SA 1011

spike,
I'm a pressure vessel and tank type guy, so am not familar with this grade of steel.  ASME II, Subsection D has tables of yield and tensile vs temperature for many grades of pressure vessel quality steel.  Perhaps you could look at the chemistry, yield and tensile of your steel vs an ASME grade and estimate info from there.  Another source, API-650, Appendix M deals with carbon and low allow steel tanks operating up to 500F.  If your steel is similar to tank and vessel grades, you will find that the tensiles won't drop at the temps you mentions, but the yields may start to show a 15% drop or so.

spike-

You'd look up the properties you need in Section II Part D, Tables U and Y-1. You didn't list the grade you're interested in; for SA-1008 grades CS-A and CS-B the yield at 350°F is 17.4 ksi (page 494) while the UTS is 40 ksi (page 421). I didn't notice any listings for SA1011, perhaps I just didn't look enough.

structural steel is underSA36 , you may bereffering to the alloy number.
1018 and others.
you are in the 45000 range, but ...
