Martensitic stainless steel plates W.-Nr. 1.4116 ( DIN X50CrMoV15 )
This is a high carbon martensitic stainless steel with moderate corrosion resistance good strength and the ability to obtain
and keep excellent hardness (Rc 56) and wear resistance.
After heat treament the grade is characterized by
* Very high hardness
* Good corrosion resistance
* Very high wear resistance
* also wrote as 5Cr13MoV
* X55CrMoV15 is a variation of 1.4116 steel
Chemical Composition ( in weight % )
With hardness HRC 55 - 57 after heat treatment, it is superior to make high end kitchen knives and out door knives like
Buck M9 Black Oxide Field knife etc.
And W.-Nr. 1.4116 ( DIN X50CrMoV15 ) stainless steel is widely used for ice skate blades.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 220
Density [g/cm3]: 7.7Thermal conductivity [W/m.K]: 30.0 Electric resistivity [Ohm mm2/m]: 0.65Specific heat capacity[J/g.K]: 0.46Magnetisable: YesCoefficient of Linear Thermal Expansion 10-6 oC-1
Heat to 730 - 780°c, cool slowly.
Harden from a temperature of 980 - 1030°c followed by oil or air quenching.
Hot forming temperature: 1100 - 800°c.
Best machined in the annealed condition.
Tough, stringy chips can be best handled by the use of chip breakers.
Carbide or ceramic tooling is recommended.
Resistant to a wide variety of media including fresh water, steam, petroleum products and alcohol.
This steel is not commonly welded due to its tendency to air harden.
If it must be welded, preheat to 260°c and post weld treat at 732 - 760°c for 6 hours followed by a slow furnace cooling to
This alloy is considered only slightly cold workable by common practices.
We are looking forward to your enquiries.
