1.2312 DIN EN ISO 4957 Tool And Die Steel DIN 40CrMnMoS8-6 Tool steel

1.2312 Tool Steel Manufacturer DIN 40CrMnMoS8-6

1.2312 Steel is a high quality plastic tool mold steel, 1.2312 is 1.2311 add about 0.08% Sulphur improve free cutting ability of 1.2311 tool steel . It belong to the high quality medium carbon, Pre-hardness(28~34HRc) plastic mould steel. It needn’t further Make heat treatment for make plasitc injection moulding. 1.2312 tool steel properties is very simliar with ASTM AISI P20S steel. At most work environment,40CrMnMoS8-6/1.2312 steel is equivalent with P20S tool steel.

Tool and die steel 1.2312 Equivalent and related speciation 

Tool and die steel 1.2312 forging 

Heat slowly, allowing sufficient time for the steel to become heated through. Begin forging at 1050°C. Do not forge below 930°C reheating if necessary. After forging, cool very slowly.

Tool and die steel 1.2312 property

DIN 1.2312 Tool steel is a plastic injection mould steel material, the steel by “super clean” produce process, pre-hardened, showing the height of micro pure and excellent homogeneous structure, excellent polishing and light etching engraving. After heat treatment, processing and polishing performance is very good, can be carried out, and can be processed, suitable for the surface treatment of chrome, material hardness, good toughness, good mechanical processing performance. Gold microstructure is martensite and bainite structure. Main be applied to in plastic steel mold.

Tool and die steel 1.2312 applications 

DIN 1.2312 is good for plastic injection moulds for thermoplastics, extrusion dies for thermoplastic, compression molds application. Tools for plastics processing and moulds for pressure die casting.

1.2312 tool steel is ideally suited for the production of moulds where improved machinability is required. Typical applications include die holders, zinc die casting dies, backers, bolsters and injection moulds. The versatility of this plastic mould tool steel with its high tensile characteristics enables uses for a variety of other applications such as shafts and wear strips,like car injection moulding, PVC, PP plastic injection molding etc.
