Abstract

Hollow bodies or holes in steel components are subjected to thermomechanical treatments above 450 deg.C with reactive gases, partic. ammonia with 5-95 vol.% N or a C-generating gas, pref. methane at 870-1000 deg.C, at gas pressures above 0.2 MPa. Pref. the treatment is carried out at constant pressure, between 0.2 MPa and 10 MPa, depending on furnace capability.
