Exhibiting impressive wear resistance, even at elevated temperatures, the martensitic welding deposit offers excellent durability against water, steam, and diluted organic acids. Maintaining scale resistance up to 900°C, it is well-suited for premium buildups and weld overlays on non- and low-alloyed base steels, as well as tool steels. Applications range from sealing faces on fittings, plungers, and claddings on rotors to continuous caster rolls and molds in ceramic industries. Selected based on carbon content, martensitic stainless steels find utility for their corrosion resistance and high strength in diverse applications like pumps, valves, and boat shafts. They are also valued for their wear resistance in cutlery, medical tools (scalpels, razors, and internal clamps), ball bearings, razor blades, injection molds for polymers, and brake disks for bicycles and motorbikes. To achieve a metallic bright finish, maintaining a clean welding area is essential. Preheating temperature ranges from 150 to 400°C, depending on the workpiece size and base material. Slow cooling and, if necessary, tempering should be applied.
