P20 High Hard Plastic Mould Steel Plate – HRC 40 Grade

P20 Steel material composition (DIN 1.2311 grade) and P20 material hardness in HRC given below.

P20 Steel material is a commonly used tool steel.

P20 Steel material (DIN 1.2311) Primarily known for its high toughness, good machinability, and ability to be heat treated to a high hardness.

DIN 1.2311 Steel is often used for making plastic molds, dies, and other tooling applications.

DIN 1.2311 Grade P20 tool steel is a low-carbon, low-alloy steel with the following chemical composition.

P20 High Hard Steel Plate is a premium-grade plastic mould steel known for its excellent toughness, hardness, and machinability. With a hardness rating of HRC 40, this steel is pre-hardened and ready for immediate use in mold-making and tooling applications. The uniform hardness throughout the plate ensures consistent performance and extended tool life.

Widely used in plastic injection molds, die-casting dies, and precision components, P20 High Hard Plastic Mould Steel offers a fine balance between wear resistance and toughness. It can be polished to a high finish, making it ideal for molds that require a smooth surface.

This steel plate delivers high performance in demanding environments, reducing the need for post-heat treatment and saving both time and cost in production.

The typical Chemical composition of P20 Steel material | P20 High Hard (DIN 1.2311 steel) includes:-

• Carbon (C): 0.28% – 0.40%
• Manganese (Mn): 1.30% – 1.60%
• Chromium (Cr): 1.90% – 2.60%
• Molybdenum (Mo): 0.30% – 0.50%
• Nickel (Ni): 0.80% – 1.20%
• Vanadium (V): 0.05% – 0.25%
• Silicon (Si): 0.80% – 1.00%
• Phosphorus (P): ≤ 0.030%
• Sulfur (S): ≤ 0.030%

P20 Steel (DIN 1.2311 steel grade) is an alloyed steel designed for use in a variety of tooling applications where toughness and dimensional stability are required.

Manufactured using high-grade alloy steel, P20 offers excellent toughness, good polishability, and dimensional stability during machining and mould making. It is particularly suited for plastic injection moulds, die casting mould bases, precision dies, and engineering components where high hardness and resistance to wear are critical.

Its high hard characteristics make it ideal for producing molds that handle abrasive plastics or high-volume production, while still maintaining a fine surface finish. The steel’s fine microstructure allows for easy machining, EDM processing, and a smooth polish—important for applications where surface finish and accuracy matter.

This steel is also commonly used in:

• Automotive mold parts

• Consumer product molds

• Compression molds

• Blow molds

• Die holders

Each plate undergoes strict quality checks for hardness, flatness, and uniformity, ensuring consistent performance across all applications.

DIN 1.2311 grade/P20 High Hard Steel is often supplied in a pre-hardened state (around 28–32 HRC) and can be further hardened through heat treatment if necessary.
