Stress relieving & solution annealing heat treatment relaxes residual stresses, provides anisotropy and increases ductility of the material.
Steps:
Load parts in the cold furnace with Ar-atmosphere.
Heat up with heating rate of 10°C/min.
Soaking time: in temperature of 1150°C ± 15°C (2102°F) for 6h (± 15min).
Quench immediately after soaking to room temperature water.
Modulus of elasticity testing according to EN ISO 6892-1 Method A, Range 1 (0.00007 1/s).
