Modulus of Elasticity according to EN ISO 6892-1 Method A, Range 1 (0.00007 1/s)
EOS NickelAlloy IN625 can be used for many applications in the stress relieved condition, which is typically performed at 870 °C (1 600 °F). Note that this heat treatment does not solutionise the alloy.
Step 1:
Stress relieve at 870 °C (1 600 °F) for 1 hour followed by rapid cooling.
