P20 1.2311Die SteelMold Steel Alloy Steel Material Engineered for Durable Mold Components and Tooling Solutions Providing Excellent Heat Treatment Capabilities

Product Description:

P20 mold steel is a commonly used pre-hardened plastic mold steel, designated P20 in the US and 3Cr2Mo in China. Here is a detailed description:

Performance Characteristics

Hardness and Wear Resistance: Pre-hardened, it possesses high hardness and wear resistance, capable of withstanding wear during mold use.

Toughness: It has high impact toughness and ductility, is not prone to brittle fracture, and can withstand a certain amount of impact force.

Machining Performance: Easy to cut, drill, and mill, meeting the complex machining requirements of mold manufacturing.

Polishing Performance: Smooth surface, easy to polish, resulting in high-quality mold surfaces, suitable for molds with specific appearance requirements.

Dimensional Stability: Minimal dimensional changes during heat treatment, ensuring mold precision and stability.

Steel Purity: Vacuum degassing and refining ensures high steel purity, suitable for plastic molds requiring polishing or texturing.

Supply Condition: P20 mold steel is typically supplied in a pre-hardened state, requiring no further heat treatment before use in mold processing. Its supply hardness is generally between HRC28-34, although some sources indicate HRC30-35 or 285-330HB (30-36HRC).

Heat treatment method: To improve mold life, pre-hardened steel can be hardened by quenching followed by low-temperature tempering. During quenching, preheat at 500-600℃ for 2-4 hours, then hold at 850-880℃ for at least 2 hours. Cool in oil to 50-100℃, then air-cool. The hardness after quenching can reach 50-52 HRC. To prevent cracking, immediate low-temperature tempering at 200℃ is necessary. After tempering, the hardness can remain above 48 HRC. Alternatively, nitriding can be performed, achieving a surface hardness of 650-700 HV (57-60 HRC), and increasing the mold life to over 1 million cycles.
