Introduction:
High carbon alloy steel plate 1.2312 / P20+S plastic mould steel is
a widely used plastic die steel in the world, as well as its
comprehensive mechanical performance is good. It has high
hardenability, and can makes large section steel earn a relatively
uniform hardness, also it has good polishing performance.
Chemical Composition(%):
C | Si | Mn | Cr | P | S | Mo |
0.35-0.45 | 0.35-0.50 | 1.40-1.60 | 1.80-2.00 | ≤0.035 | ≤0.015 | 0.30-0.55 |
Feature:
Plastic mould steel with excellent machinability properties because
of the high S content, good toughness properties, good dimensional
stability, requiring no heat treatment, 280-325HB hardened and
tempered condition, suitable for nitriding to increase
wear-resistance, not suitable for chrome plating to increase
wear-resistance, not suitable for chrome plating and polishing.
Recommend heat treatment:

Heating temperature/℃ | Cooling way | Hardness (HRC) | Tempering temperature /ºC | Cooling way | Hardness (HRC) |
870-890 | Oil Cooling | 50-54 | 550-640 | Air Cooling | 28-36 |
Applications:
For the production of plastic molds and casting low melting metal
material. This steel has good machinability and mirror grinding
performance.
Delivery condition:
Hot rolled or forged, black surface.
Hardenss: pre-hardening or tempering to 28-33HRC.
