High carbon stainless steel round bars AISI 420C - W.Nr.- 1.4034 - DIN X46Cr13
DIN X46Cr13 Stainless steel is a grade that is commonly used in the commercial knife making industry.
DIN X46Cr13 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.
DIN X46Cr13 has fair toughness and good corrosion resistance and can be hardened to RC 56 - 59.

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.
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.
Nitriding decreases the corrosion resistance of stainless steels and is generally not recommended for
