Applications:
The 1.2311 tool steel is ideally suited for the production of plastic moulds. Typical applications include die holders, zinc die casting dies, backers, bolsters and injection moulds. The versatility of 1.2311 tool steel with its high tensile characteristics enables uses for a variety of other applications such as shafts, rails and wear strips
Heat Treatment:
| 1.Quench: 950-980`C cold oil(need re-preheat~500`C-850`C)HRC≥60 |
| 2.Eliminate stress, stabilize framework tempering, (180-200`C)≥2 hours HRC60-62 |
| 3.If it is necessary, it could be changed into 320-350`C≥2 hours backfire HRC≥60-62 |
| 4.Annealing: 780-800`C slow cooling |
Description:
1.2311 tool steel . As an alloy tool steel grade 1.2311 is commonly supplied in the hardened and tempered condition with a supply hardness of approximately 300HB. The 1.2311 tool 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. And 1.2311 tool steel 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.
