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.

Heat Treatment

The following is material 1.4034 stainless steel heat treatment, such as hot forming, annealing, quenching, tempering.

Standard Designation (Steel number) Hot forming Heat treatment Annealing Quenching Tempering Temperature, °C
Temperature, °C Type of cooling Temperature, °C Type of cooling Temperature, °C Type of cooling
DIN EN 10088-2 X46Cr13 (1.4034) 1100 to 800 slow cooling Annealed 730 to 790
+QT850 1000 to 1100 oil, air 200 to 350
DIN EN 10088-3 Annealed 750 to 850 furnace, air
+QT850 950 to 1050 oil, air 650 to 700

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.
