K600 Steel

K600 Steel

Steel name: K600
Diagram No.: 2254
Mat.No. (Wr.Nr.) designation: ~1.2767
DIN designation: 45NiCrMo16
UNI designation: ~42NiCrMo15 7
AFNOR designation: ~Y35NCD16
Chemical composition in weight %: 0.48% C, 0.23% Si, 0.40% Mn, 1.30% Cr, 0.25% Mo, 4.00% Ni
Steel group: Cold work tool steels
Properties: Cold work tool steel with high toughness and full hardenability, also large dimensions. High impact strength and compressive strength. For oil and air hardening. Good polishability.
Applications: Highly stressed coining tools, cutlery dies, hobbing tools, cold shear blades for heavy - gauge material, plastic moulds.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 840 to 870°C (1544 to 1598°F), oil, salt bath (300 to 400°C / 572 to 752°F), air. Holding time after temperature equalization: 15 to 30 minutes. Obtainable hardness: 53 - 57 HRC in air, 54 - 58 HRC in oil or salt bath.
Tempering: Slow heating to tempering temperature immediately after hardening/time in furnace 1 hour for each 20 mm of workpiece thickness but at least 2 hours/cooling in air. For average hardness figures to be obtained please refer to the tempering chart. For certain cases we recommend to reduce tempering temperature and increase holding time.
Diagram note: Tempering chart: Hardening temperature: 850°C (1562°F). Specimen size: square 20 mm.
