Plastic Mould Steel P20 1.2311 Alloy Steel Round Bar Tool And Die Steel

Plastic Mould Steel P20 1.2311 Alloy Steel Round Bar tool and die steel


1.2311 Tool steel is a type die steel which has been pre-hardened by the "super clean" production process, showing a high degree of purity and excellent uniform structure, excellent polishing and light etching engraving.1.2311 is commonly supplied in the hardened and tempered condition with a supply hardness of approximately 300HB.

This steel gives an excellent polished finish and is one of the most widely accepted specifications for machine cut plastic moulds and zinc die casting dies. This grade gives excellent wear resistance but if maximum surface hardness is required for compression moulding plastic dies or similar tools, the steel can be case hardened or nitrided.
