AISI 420C, W.-Nr. 1.4034 ( DIN X46Cr13 ) Martensitic stainless steel strips
Designation by Standards
Chemical Composition ( in weight % )
W.-Nr. 1.4034 ( 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 DIN X46Cr13 became such a popular grade.
DIN X46Cr13 has fair toughness and good corrosion resistance and can be hardened to RC 55.
ApplicationsAll kinds of cutting tools - knives, shears, surgical instruments, moulds for plastics production,
as well as for surgical instruments and measuring gauges.Physical properties (avarage values) at ambient temperatureModulus of elasticity [103 x N/mm2]: 220 Density [g/cm3]: 7.73Thermal conductivity [W/m.K]: 30.0
Electric resistivity [Ohm mm2/m]: 0.65Specific heat capacity[J/g.K]: 0.46
Coefficient of Linear Thermal Expansion 10-6 oC-1
Modulus of Elasticity [103 N/mm2]
Heat to 730-780°c, cool slowly in furnace or air. Structure is ferrite with spherical carbides.
Harden from a temperature of 980-1030°c followed by oilor air quenching.
Hardness after quenching is HRC 56.Tempering
Tempering temperature: 100-200°c.
Tempering Temperature (°c) vs. Hardness (HRC)
Hot forming temperature: 1100-800°c.
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/ER 420.
