Heat input plays an important role in the microstructural development of 12%Cr martensitic stainless steel. The microstructure of low-C 12%Cr martensitic stainless steel resulting from laser cladding was investigated. For 410L a ferritic microstructure is predicted according to the modified Schaeffler diagram for laser welding. Experiments were performed which included the addition of Ni and Mo to in order to obtain a fully martensitic microstructure. Electrolytic etching with oxalic acid indicated that sensitisation occurred at the ferrite grain boundaries for the 410L but no sensitisation occurred with the fully martensitic microstructure of the modified 410L
