  • Mat.No. 1.2235/DIN 80CrV2/AISI L2

Designation by Standards

Mat. No.DINENAISI
1.223580CrV2-L2


Chemical Composition (in weight %)

CSiMnCrMoNiVWOthers
0.800.330.400.55--0.20--


Applications
Circular saws for timber, saws for non ferous, machine saws, measuring tools, tools for wood working (axes, knivesp, punches, guide rods, twist drills, reamers, ejector pins, dentist’s drills.


Physical properties (average values) at ambient temperature

Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.80
Thermal conductivity [W/m.K]: 33.5


Soft Annealing

Heat to 710-850oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 220.


Stress Relieving

Stress relieving to remove machining stresses should be carried out by heating to approx. 650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.


Hardening
Harden from a temperature of 810-840oC, 780-810oC followed by oil (up to diamter 15 mm) or water (for diameter higher then 15 mm) quenching Hardness after quenching is 64 HRC.

Forging
Hot forming temperature: 1050-850oC.


Machinability

No data.

Corrosion Resistance
This is an alloy steel and it is not corrosion resistant. It will rust unless protected.
