What is P20 High Hard Steel? [Plastic Mould Steel Explained]

P20 High Hard Steel is a premium alloy tool steel developed primarily for manufacturing plastic mold bases, injection molds, tool holders, die casting dies, and related precision tool applications. It belongs to the family of cold work/mould steels and is renowned for its:

• Consistent hardness throughout large and small cross sections

• Enhanced polishability, making it ideal for mirror-finish molds

• Good dimensional stability during machining and heat treatment

• Excellent machinability compared to higher-alloyed tool steels

• Reliable toughness, minimizing the risk of cracking or chipping during molding operations

P20 is typically supplied in the pre-hardened condition, saving time and cost on hardening heat treatments. High Hard grades—like 34 HRC to 38 HRC and 39 HRC to 44 HRC—offer superior wear resistance and durability, essential for long production runs and engineering safety.

P20 Steel Properties – Key Mechanical and Physical Features

Note: The above properties may slightly vary depending on heat treatment condition, cross-sectional thickness, and steel manufacturer.

P20 Steel Chemical Composition (% Typical, may vary by variant)

(The exact range may differ between manufacturers. Always refer to the test certificate for your supplied batch.)

Advantages of P20 High Hard Steel [Why is P20 the best plastic mould steel?]

• Supplied Pre-Hardened: Eliminates the need for additional hardening treatments, reducing lead times and risk of distortion.

• Easy to Machine: Uniform hardness allows for fast, accurate machining and polishing.

• Good Through-Hardening: Consistent properties, even for large mold blocks.

• High Toughness: Reduces the likelihood of cracking/chipping under shock loads during molding.

• Great Polishability: Achieve high-gloss, mirror finish on mold surfaces—vital for clear or glossy plastic parts.

• Dimensional Control: Excellent stability during machining and service.

• Universally Recognized: Supported by global standards, equivalent grades, and cross-industry compatibility.

• Versatile Use: Can be nitrided, flame/surface hardened, coated (PVD, CVD) for enhanced performance.

• Cost-Effective: Extended tool and mold life reduces maintenance and downtime, lowering operational cost per part.

Difference Between P20 High Hard Steel Grades [34 HRC – 38 HRC vs. 39 HRC – 44 HRC]

The main difference between P20 High Hard Steel Grade 34–38 HRC and Grade 39–44 HRC is surface hardness and thus the mold’s durability.

When to Choose Each Grade:

• Use 34–38 HRC for: Complex tooling requiring maximum machinability, repair jobs, prototyping, medium-to-large runs.

• Use 39–44 HRC for: Highly abrasive or glass-filled material molds, high-production environments, components with tight tolerances on wear, or where dimensional integrity over long service is paramount.

P20 Steel Equivalent Grades – Worldwide Standards and Alternatives

Many international standards cover P20 or equivalent plastic mold steels. Here is a quick comparison of global equivalents and alternative grades:

P20 vs. Alternative Steels

• NAK80, 718/S, and 1.2738 are popular alternatives with added nickel for deeper through-hardening, improved toughness, and better polishability.

• For even more complex surfaces, grades like H13, S136, and other high-hardened tool steels are recommended, but at the expense of machinability.

Always consult with our experts to select the right grade for your specific application, balancing hardness, polishability, and tool life.
