Hot Tensile Test of ASTM A182 (F51)
Hot Tensile Test of ASTM A182 (F51)
(OP)
Hi all,
Does anyone know why there would be a dip in a high temperature (190 deg C) tensile test of an F51 stainless steel? The room temperature tensile test is as expected but the high temperature tensile test a lot is lower than expected.
Any ideas?

RT : 103 KSI (UTS)
Elevated temp: 54 KSI (.2% Yeild)
Elevated temp: 86 KSI (UTS)
Elevated temperature = 190 deg C

The F51 stainless steel is a Duplex 2205. From the literature I have seen for this duplex ss at room temperature and at 200 deg C, the following properties are published;
RT
UTS ~92-121 Ksi
0.2% YS 67 Ksi min
200 deg C
UTS ~ 80 Ksi
0.2% YS ~ 46 Ksi

Its good to know that my data is consistent with the literature.
The worry I have is the elevated temperature UTS. I would normally be expecting 88 Ksi.

On what basis ar you expecting 88 ksi? Is this for the base material or weld?
Thanks and regards
