EOS NickelAlloy IN625 for EOS M 400-4 | 40 µm HiPro

EOS M 400-4 - 40 µm - TRL 5

Process Information Metal

This process parameter includes two variations of the exposure set: the first one provides better productivity while the second one enables low angle buildability down to 20°. The low angle buildability can be optimized further through the part geometry and the length of overhang.

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.
