DIMO P20 Steel

DIMO P20 Steel

Steel name: DIMO P20
Diagram No.: 2329
AISI/SAE designation: P20
Chemical composition in weight %: 0.20-0.40% C, <0.40% Si, 0.80-1.40% Mn, <0.025% P, <0.002% S, 1.00-2.00% Cr, 0.20-0.50% Mo
Steel group: Plastic mould steels
Properties: DIMO P20 is a modified version of AISI P20 according to ASTM A681. Compared to DIMO 2311 and DIMO 2738, DIMO P20 has, as a result of its adjusted analysis resulting in a lower carbon equivalent, advantages at repair welding and at thermal-chemical surface layser treatment, as e.g. nitriding.
Applications: DIMO P20 is a prehardened 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. DIMO P20 is a typical toolsteel for the mold construction in North America and South East Asia.

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 (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 850 °C (1560 °F) in oil.
