Laser cladding offers distinct advantages including low dilution, low heat input,less distortion, increased mechanical and corrosion properties excellent repeatability and control of process
parameters. Solidification of laser cladded martensitic stainless steel is primarily austenitic. Microstructures consisting of martensite and retained austenite was obtained for 0.4C-13Cr (420) and
16Cr-2Ni (431). Almost fully austenitic microstructures were obtained for 0.4C-15Cr-5Ni (400 series) alloy. Materials expected to consist of a fully martensitic structure is proposed for laser cladding applications
