Hot tensile strength of duplex stainless steel

Hot tensile strength of duplex stainless steel

Hot tensile strength of duplex stainless steel

Does anybody have, or know where I can get hold of, information about the elevated temperature tensile strength of duplex stainless steels, particularly ASTM A890 grade 4A. This is the cast version od UNS S31803. I am looking for information at temperatures above ambient up to around 300 deg C.


RE: Hot tensile strength of duplex stainless steel

According to ASME 2D Tensile values for S31803 are as follows: -

Degrees F        Tensile Strength KSI
-20 to 200        90
300            86.8
400            83.5
500            81.6
600            80.7
650            80.5

All the specification listed have the same values, but your specific grade is not listed.

RE: Hot tensile strength of duplex stainless steel

Thanks, Welding1.

Does ASME 2D also list proof/yield strength requirements for the same material?  If so, what are they?
