DIN EN 1.4034 Stainless steel material X46Cr13
The material X46Cr13 (DIN EN 1.4034 stainless steel) is a European EN standard martensitic stainless steel. It has good mechanical and polishing properties, but low weldability. Due to its higher carbon content than 1.4031 (X39Cr13), the steel is harder than 1.4031. 1.4034 steel has good corrosion resistance in chloride-free media and weak organic acids and bases.
