A36 vs Temperature Strength Chart

[Rabbit12]

I'm looking for a strength vs. temperature graph or table for A36 steel. I'm not having much luck finding that information. Anyone have a reference they can point me to?

ASME B&PV Code, Section II, Part D should have that information (A36=SA36).

 

[TGS4]

From ASME Section II, Part D, Table Y-1 (Yield Strength Values):

Temperature     Yield Strength (Short-term - in ksi)
100°F              36.0
150°F              33.8
200°F              33.0
250°F              32.4
300°F              31.8
400°F              30.8
500°F              29.3
600°F              27.6
650°F              26.7
700°F              25.8
750°F              24.9
800°F              24.1
850°F              23.4
900°F              22.8
950°F              22.1
1000°F             21.4

TGS4 has some good info. AISC doesn't give a chart (that I've seen), but they do say steel loses 23% of it's yield strength at 800 F [426 C], 37% at 1000 F [537 C], and 63% of its strength at 1200 F [648 C].

Thanks guys. That's what I was looking for.

Creep becomes non-negligible at 650°F (reference - Table 4.1 in API 579-1/ASME FFS-1 (2016)).
