Effects of Filler Wire Composition and Post-Weld Heat Treatment on the Mechanical Properties of 4Cr13 Steel Welded Joints

4Cr13 martensitic stainless steel is widely used for plastic molds, but welding repair can produce heterogeneous weld/HAZ microstructures and a strength–toughness trade-off. This study evaluates how filler-wire composition and post-weld heat treatment affect the mechanical performance of repaired 4Cr13 steel. TIG weldi...
