EN/DIN
X46Cr13
EN 1.4034 stainless steel is a martensitic stainless steel formulated for primary forming in forged products. 1.4034 is the EN numerical designation for this material. X46Cr13 is the EN chemical designation.
It has a moderately low structured energy among forged martensitic stainless steels. In addition, it has a moderately high electrical conductivity and can have a moderately low ductility.
The properties of 420 (EN 1.4034) stainless steel include two common variations. This page shows the summary ranges of both. For more specific values, just follow the links below. The graphic bars on the following material properties cards compare EN 1.4034 stainless steel with: forged martensitic stainless steels (top), all ferrous alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the respective set. The half filled bar means 50% of the highest value, and so on.

Weldability
Due to its high carbon content, 1.4034 is not suitable for welding. If welding cannot be avoided, preheat to 350 ° C-400 ° C, and the temperature after heat treatment is about 650 ° C.
Corrosion Resistance
DIN EN 1.4034 is not resistant to intergranular corrosion at delivery. It has good corrosion resistance in chlorine-free and acid-based environments; the polished surface in the annealed state has good corrosion resistance; It is not recommended to be used in annealed or high temperature conditions to maintain corrosion resistance.
