Structural steel Yield Strenght in Hot Ambient Temperature

[StructMB]

Hi,
I am using structural steel sections (ASTM- A572- Gr. 50) in an industrial environment where temperature gets relatively high around specific equipment. More precisely the steel will be at around 150 degree Celsius (300 degree Fahrenheit). I was wondering if the steel yield strength will be reduced at these operating temperatures?

regards,

Check out appendix 4 "Structural Design for Fire Conditions" in the AISC 14th Edition. This appeared in previous editions as well. I just do not have them in front of me right now.

Thank you "Tolchijb", Appendix 4 has exactly the information I was looking for.
