Similar Steel Grade-DIN/W.Nr. 1.2312, GB 40CrMnMoS86

Chemical Composition (%)

AISI P20+S Pre-hardened Plastic Mould Steel is a high tensile alloy tool steel grade supplied in the hardened and tempered condition. Similar to P20 (1.2311) but with a higher sulpher content which provides much improved machinability.

Toughness properties,

Good wear resistance,

Uniform hardness in all dimensions,

Dimensional stability, requiring no heat treatment.

Not suitable for chrome plating, polishing and etch graining.


suited for the production of moulds where improved machinability is required, include bolsters and injection moulds, die holders and zinc die casting dies. It is a high tensile characteristics suitable for many other applications such as shafts and wear strips.
