Mat.No. (Wr.Nr.) designation: ~1.2311
DIN designation: ~40CrMnNiMo8-6-4
AISI/SAE designation: ~P20
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
Steel group: Plastic mould steels
Properties: DIMO 2311 is a modified version of 1.2311 according to Stahl-Eisen-Liste, respectively 40CMD8 according to NF A 35590, 40CrMnNiMo8-6-4 according to DIN EN ISO 4957 and a modified version of P20 according to ASTM A681.
Applications: DIMO 2311 is a hardened CrMnMo-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.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 840 - 860 °C (1540 - 1580 °F)/oil; for low wall thicknesses air cooling or warm bath hardening at 200 - 230 °C (390 - 450 °F) are possible.
Tempering: In accordance with tempering diagram to required hardness.
Diagram note: The values in the diagram are mean values on samples, diameter 25 mm (1 in), length 50 mm (2 in), hardened at 850 °C (1560 °F) in oil.
