The analysis of the reparation procedure of the damaged turbine diaphragm from the ironworks plant, which was subjected to wear during the long-term exploitation process, is presented in this paper. The two-thirds of the bearing volume of the turbine diaphragm, made of grey cast iron EN-GJL-150, were damaged, and its functional properties were lost. The reparation was executed by the multi-layer hard-facing process. The procedure included verification of the material’s chemical composition, mechanical properties and metallographic structure, necessary for definition of the appropriate methodology for the part’s rehabilitation. The hard-facing was executed with preheating, as well as the post-welding heat treatment, with specifically selected filler materials and all the adequate welding process parameters. The executed hard-facing procedure turned out to be the cost efficient since, as a rule, the costs of reparation did not exceed 20 % of the price of that would be paid for acquiring the new part.
