2312 special steel

  Product Description  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. 1.Toughness properties, 2.Good wear resistance, 3. Uniform hardness in all dimensions, 4.Dimensional stability, requiring no heat treatment. 5.Not suitable for chrome plating, polishing and etch graining.

Heat Treatment:
Forge: at 850°C-1050°C Cool slowly and anneal immediatedly
Anneal: at 740°C-760°C Cool slowly in furnace
Stress Relieve: at to 600°C-650°C Cool in still air
Harden: Preheat at 580°C-680°C raise to 850°C-880°C Cool in air, iol or into salt bath held at 50°C-100°C and then air cool
APPLICATIONS:  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.    Chemical Composition (%)
