  • Mat.No. 1.2515/DIN 100WV4

Designation by Standards

Mat. No.DINENAISI
1.2515100WV4--


Chemical Composition (in weight %)

CSiMnCrMoNiVWOthers
1.020.180.230.18--0.151.05-


Applications
Knives for wood working, tobacco cutting and knives for graphic industry.


Physical properties (average values) at ambient temperature

Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.90


Soft Annealing

Heat to 720-750oC, cool slowly in furnace. This will produce a maximum Brindle hardness of 230.


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 780-820oC, 820-860oC followed by water or oil quenching. Hardness after quenching is 64-65 HRC.


Tempering

Tempering temperature: 150-250oC. Hardness after tempering is 59-64 HRC.
