DIMO 2738 Steel

Steel name: DIMO 2738
Diagram No.: 2325
Mat.No. (Wr.Nr.) designation: ~1.2738
DIN designation: 40CrMnNiMo8-6-4
Chemical composition in weight %: 0.35-0.45% C, 0.20-0.40% Si, 1.30-1.60% Mn, <0.025% P, <0.002% S, 1.80-2.10% Cr, 0.15-0.25% Mo, 0.90-1.10% Ni
Steel group: Plastic mould steels
Properties: No data
Applications: DIMO 2738 is a prehardened CrMnNiMo-alloyed tool steel for the construction of plastic molds with superior surface requirements on molds. It is characterized by excellent polishability, photoetchability, spark erosion behaviour and dimensional stability as well as good machinability. DIMO 2738 shows a better through-hardening compared to DIMO 2311.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 840 - 860 °C (1540 - 1580 °F); air cooling or warm bath hardening at 200 - 230 °C (390 - 450 °F).
Tempering: In accordance with tempering diagram to required hardness (min. 1 h/25 mm (1 in) wall thickness).
Diagram note: The values in the diagram are mean values on samples, diameter 25 mm (1 in), length 50 mm (2 in), hardened at 840 °C (1540 °F) on air.
