Temperature Derating fcator
Temperature Derating fcator
(OP)
Hi
I am trying ot find the temperature derating factor of the below materials
1. AISI 4140 (YTS 80K PSI)
2. MONEL K500 (YTS 95K PSI)
3. AISI 630 (YTS : 105K PSI)
The specified yeild strength are for ambient temperature. But i am trying to find the yeild strength at 120 degree and i believe it is going to change. Is there a formula or a data sheet or any method for determining the derated yeild strength.
