We are professional X46Cr13(1.4034) Forged/Forging/Rolled Rings factory from china
DIN X46Cr13 Stainless steel is a grade that is commonly used in the commercial knife making industry.
X46Cr13 can be sharpened to a very fine cutting edge and a mirror finish.
It is becuase of these reasons that X46Cr13 became such a popular grade.
DIN X46Cr13 has fair toughness and good corrosion resistance and can be hardened to RC 55.
Applications
All kinds of cutting tools - knives, shears, surgical instruments, moulds for plastics production,
as well as for surgical instruments and measuring gauges.

Soft Annealing
Heat to 730-780°c, cool slowly in furnace or air. Structure is ferrite with spherical carbides.
Hardening
Harden from a temperature of 980-1030°c followed by oilor air quenching.
Hardness after quenching is 56 HRC.
Tempering
Tempering temperature: 100-200°c.

Forging
Hot forming temperature: 1100-800°c.
Machinability
Similar to machining some of the high carbon tool steel, this alloy has tough, stringy chip build-up.
Corrosion Resistance
420 is resistant to the atmosphere, fresh water, dilute acids and alkalis and fruit and vegetable juices.
Welding
Not commonly welded due to its air hardening characteristics.
Welding may be performed after preheating to 149-204°c with post weld tempering at temperature
for 2 hours. Filler metal should be AWS E/ER420.
