1.2379 Steel

1.2379 Steel

Steel name: 1.2379
Diagram No.: 2225
Mat.No. (Wr.Nr.) designation: 1.2379
DIN designation: X153CrMoV12
AISI/SAE designation: ~D2
Chemical composition in weight %: 1.53% C, 0.30% Si, 0.35% Mn, 12.00 Cr, 0.80% Mo, 0.80% V
Steel group: Cold work tool steels
Properties: High-alloy steel for through-hardening with moderate machinability; extremely wear resistant and low warpage, good dimensional stability, toughness and through hardenability.
Applications: Mould plates and inserts as well as cutting punches, wear plates and cutting dies with high requirements for wear resistance.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: Curing temperature: see tempering chart, quenching in oil/air/hot bath, obtainable hardness: 63-65 HRC.
Tempering: Slow heating to tempering temperature (to avoid forming of cracks), immediately after hardening; triple tempering at max. secondary hardening temperature is recommended; rapid cooling following the tempering improves the dimensional stability; maximum hardness achievable after tempering: 60-62 HRC.
