DIN EN 1.4034 Stainless Steel X46Cr13 Material Datasheet Equivalent Properties Composition
DIN EN 1.4034 Stainless Steel X46Cr13 Material
X46Cr13 material (DIN EN 1.4034 stainless steel) is a European EN standard martensitic stainless steel. It has good polishing and mechanical properties, but poor 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 non-chloride media and weak organic acids and bases.

Welding
Due to the high carbon content, 1.4034 is not suitable for welding. If welding cannot be avoided, preheat to 350 °C-400 °C and post heat treatment temperature is about 650 °C.
Corrosion Resistance
(PREN = 12,5-14,5)
DIN EN 1.4034 is not resistant to intergranular corrosion upon delivery. It has good corrosion resistance in non-chloride and acid-base environments; polished surface under tempered condition have good corrosion resistance; in order to maintain good corrosion resistance, it is not recommended to be used in annealed or high temperature conditions.
Use & Application
Hardened steel for cutting tools, table knives, machine knives, razors, scissors and measuring tools, ball bearings, skates, etc.
