Understanding P20 Tool Steel: What Makes It an Industry Staple?
P20 tool steel is a versatile, low-carbon mold steel that belongs to the chromium-molybdenum tool steel family. Standardized by the American Iron and Steel Institute (AISI), the P-type group of steels is renowned for its exceptional balance of properties. The “P” in its name stands for “Plastic Mold,” which is its primary application, but its utility extends far beyond.
The most significant advantage of P20 steel is that it is typically supplied in a pre-hardened condition, usually around 28-32 HRC (Hardness Rockwell C). This pre-hardening eliminates the need for risky and time-consuming heat treatment after machining the final mold or die, saving significant time and cost for manufacturers. This unique characteristic makes it the go-to choice for applications requiring high toughness, good machinability, and excellent polishability.
Key Characteristics at a Glance:
-
Excellent Machinability: Even in its pre-hardened state, P20 can be easily machined.
-
High Polishability: Capable of achieving a super-fine, high-gloss finish, essential for high gloss plastic components and products.
-
Uniform Hardness: Possesses consistent hardness throughout the cross-section, even in large blocks.
-
Good Toughness: Offers superior resistance to chipping and cracking under operational stress.
-
Weldability: Can be effectively welded, allowing for easy repair and modification of molds.
At Milano Special Steel, we offer P20 and its equivalent steel grades, ensuring you receive a product with a perfect chemical composition tailored for superior performance in aluminum die casting, pressure die casting, and plastic mold steel applications.

Mechanical Properties of P20 Steel
The following table details the typical mechanical properties of P20 tool steel in its pre-hardened state (approx. 300 HB / 32 HRC).
Property | Typical Value | Significance for Applications |
---|---|---|
Hardness (Supplied) | 28-34 HRC (270-320 BHN) | Ideal balance for good machinability and wear resistance. Eliminates post-machining heat treatment. |
Tensile Strength | 965 – 1030 MPa | Indicates the material’s ability to resist being pulled apart, crucial for withstanding clamping forces in molds. |
Yield Strength | 825 – 930 MPa | The point at which the steel begins to deform permanently. A high value ensures the mold retains its shape. |
Toughness (Charpy Impact) | ~20 J | Demonstrates excellent resistance to fracture from sudden impacts, preventing chipping of mold edges. |
Modulus of Elasticity | 205 GPa | Measures the material’s stiffness, ensuring minimal deflection under high injection pressures. |
Machinability | Excellent (~80% of W1 steel) | Allows for complex mold cavities to be created efficiently and with a superior surface finish. |
Physical Properties

---|---|
Density | 7.85 g/cm³ |
Thermal Conductivity | 29.0 W/m.K |
Coefficient of Thermal Expansion | 12.8 µm/m°C (at 20-425°C) |
Heat Treatment Specifications
While P20 Steel is used in its pre-hardened state, it can be further heat-treated for specific applications requiring higher hardness.
-
Hardening: Heat to 830-870°C, followed by oil quenching. This can achieve a hardness of up to 52 HRC.
-
Tempering: After hardening, tempering at appropriate temperatures (e.g., 500-600°C) is crucial to relieve stress and achieve the desired final hardness and toughness.
-
Nitriding: For extreme surface wear resistance, P20 can be gas or liquid nitrided. The nitriding process creates a very hard surface case (650-700 HV) without distorting the core of the tool.
P20 Material Chemical Composition: The Foundation of Performance
The precise balance of alloying elements in the P20 material composition is what defines its unique properties. Milano Special Steel guarantees a perfect chemical composition in every product, verified through rigorous testing, to ensure consistent and reliable performance.
