HEAT TREATMENT MICROSTRUCTURE

Perform heat treatment under an argon atmosphere. Heat up to 1150°C. Maintain temperature for 1 hour. Allow the components to cool down to 300°C in the oven.

Components made from the cobalt-chromium alloy remanium star CL display a homogeneous, pore-free structure after they are constructed by means of the metal laser melting process LaserCUSING.
