High Carbon Martensitic EN 1.4034 DIN X46Cr13 Stainless Steel Round Bar
High Carbon Martensitic EN 1.4034 DIN X46Cr13 Stainless Steel Round Bar
W.-nr. 1.4034, DIN X46Cr13 Stainless steel is a grade that is commonly used in the commercial
knife making industry. X46Cr13 stainless can be sharpened to a very fine cutting edge and a mirror finish.
It is becuase of these reasons that 420C became such a popular grade.
X46Cr13 stainless has fair toughness and good corrosion resistance and can be hardened to RC 56 - 59.
Chemical Composition ( weight % )
| Grade | C | Si | Mn | Cr | Ni |
| X46Cr13 | 0.43 - 0.50 | 1.00 max | 1.00 max | 12.50 - 14.50 | 0.50 max |
Applications
- Cutlery
- Custom knives
- Scissors
- Surgical tools
- Mechanical engineering parts
Corrosion Resistance
EN 1.4034, DIN X46Cr13 stainless steel is characterised by good corrosion resistance in mild
dometic and industrial environments, including fresh water, organic materials, mild acids, various
petroleum products. X46Cr13 also provides extreme high strength, hardness and wear resistance
when in the hardened and tempered condition.
Thermal Treatments
Preheat : Optional preheat stage for unbalanced geometries or complex designs - 1100/1250°F (590/675°c),
equalize, standard preheat stage - 1400/1500°F (760/815°c), equalize.
Austenize : 1850/1900°F (1010/1020°c), equalize, 30/45 minutes at temperature.
Quench : Air, positive pressure vacuum to below 125°F (50°c)(2 bar minimum).
Interrupted oil to below 1000°F (540°c). Air cool to 150°F (65°c). Temper immediately.
Temper : 400/800°F (205/425°c), hold 2 hours at temperature, air cool. Temper twice.
Avoid tempering between 800 and 1100°F, due to a decrease in toughness and corrosion resistance.
Cryogenic Treating : Refrigeration treatments may improve long term dimensional stability by
transforming retained austenite.
Refrigeration treatments should generally be performed after the first temper, and must be followed by a temper.
Surface Treatments
Nitriding decreases the corrosion resistance of stainless steels and is generally not recommended for stainless steels.
