Thermal Stress Relaxation
Stress remaining after thermal relaxation as a function of Larson-Miller
parameter (F. R. Larson, J. Miller, Trans
ASME74 (1952) 765–775) given by:
P = (20 + log(t))*(T + 273)*0.001.
Time t in hours, temperature T in °C.
Example: P = 9 is equivalent to
1.000 h/118 °C.
Measured on rolled to temper specimens parallel to rolling direction. Total
stress relaxation depends on the
applied stress level. Furthermore, it
is increased to some extent by cold
deformation.

Fatigue Strength
The fatigue strength is defined as the maximum bending stress amplitude which a material withstands for 107 load cycles
under symmetrical alternate load without breaking. It is dependent on the temper tested and is about 1/3 of the tensile
strength Rm.
