P20/1.2311/ 3Cr3Mo Steel

P20/1.2311/ 3Cr3Mo Steel


P20 is an American grade of pre-hardened plastic mold steel.

(This steel corresponds to Chinese grade: 3Cr2Mo ; German DIN standard material number 1.2311 )

Chemical composition content:

C:0.28-0.40 Si:0.20-0.80 Mn:0.60-1.00 S:≤0.030

P:≤0.030 Cr:1.40-2.00 Mo:0.30-0.55

    P20 mold steel characteristics

    1.P20 mold steel has excellent hardenability and thermal stability. It can maintain its excellent properties at high temperatures and is not prone to brittle fracture. Its high hardness and good wear resistance make it ideal for manufacturing high-quality molds.
    2.P20 mold steel has excellent processing performance and mechanical properties. It is easy to process into complex shapes and sizes, and is convenient for cutting, drilling and processing operations, and can meet the requirements of various mold manufacturing.
    3.P20 mold steel has good hardening properties and can achieve the required hardness and toughness through heat treatment.
    4.P20 mold steel’s low fracture tendency and high toughness make it easy to shape and process. It can be used to manufacture large and complex molds to meet various special needs and provides mold manufacturers with greater design freedom.
    5.P20 mold steel has good weather resistance and can resist corrosion from long-term use and harsh environments, extending the service life of the mold.
    6.P20 mold steel has excellent anti-wear and corrosion resistance,can maintain a stable service life in various harsh environments, and improve the stability and durability of the mold.
    In short, P20 mold steel is a high-quality mold material. After pre-hardening, the hardness is evenly distributed in the material cross-section. It has good EDM performance, polishing performance and machinability, and has excellent mechanical properties and durability.
