1.2312H

Description:

1.2312, also known as P20+S or 40CrMnMoS8-6, is a pre-hardened plastic die steel belonging to the chromium-nickel-molybdenum alloy steel. The material has been hardened and tempered before leaving the factory. 

 

Chemical composition content :

C:0.35-0.45 Si:0.30-0.50 Mn:1.40-1.60 S:0.05-0.10
P:≤0.030  Cr:1.80-2.00 Mo:0.15-0.25    

 

    1.2312H Characteristics

    1. Excellent mechanical properties and plasticity
    2. High hardness, uniform metallographic structure, good polishing, hardenability and toughness, as well as excellent processing properties, suitable for the manufacture of complex shapes. Its excellent hardness and wear resistance make it an ideal material for the manufacture of injection molds.
    3. It has high strength, high rigidity and good wear resistance. Its hardness is usually in the pre-hardness range of 28~34HRC, which makes it have excellent application performance in mold manufacturing.
