Mat.No. 1.2747/DIN X210Cr12/AISI D3

Designation by Standards

Chemical Composition (in weight %)

Applications
Pilger mandrels up to diameter 140-200mm.

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [10³ x N/mm²]: 210
Density [g/cm³]: 7.85

Soft Annealing
Heat to 620-680^oC, cool slowly.

Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to 600-650^oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

Hardening
Harden from a temperature of 840-870^oC followed by oil or air quenching.

Tempering
Tempering temperature: 620-670^oC.

Forging
Hot forming temperature: 1050-850^oC.

Forms manufactured
Please see the  Dimensional Sales Program.
