YS and UTS for A516 Gr 70 Material for temp up to 1400 degF

[SooCS]

Will appreciate if you material expects can advise where I can find the yield and ultimate tensile strengths of steel material like A516 Gr 70 for temperature ranges from 600 deg F to 1400 deg F.

Thanks in advance

Carbon steel at 1400 deg. F? I don't have actual numbers right here now, but the YS will be VERY low-a few ksi if that! Plus it will oxidize rapidly if it's in air. What application do you have?

Metalguy,

Thanks for your response.

There is no specific application. I just want to prove to myself that the API RP 521 suggested the blowdown duration of 15 min when a pressure vessel is under a fire is too long. I suspect the vessel will bleve before it is blown down to atm pressure.

Hope to hear from you again.
