Summary

Stellite 6 is a cobalt base superally consisting of a matrix containing dispersed carbides. It is a wear resistance alloys, with excellent corrosion and mechanical properties up to 500 deg C. Becuase of its properties it used in valves seats and gates, pump shafts and bearings, erosion shields and rolling couples, but also aero engines, gas turbines and nuclear industry.

Highlights

This material can be printed in combination of a wide variety of steel grades, AISI 316 and 316L

General explanation
Printing strategies
Straight lines strategy: several welding beads overlapped next to each other
Oscillation: continuous zig-zag bead that fills the entire layer

Heat treatement
Stress relief: due to the high residual stresses build up in the WAAM product, this heat treatment is necessary to minize residual stresses.
