| SUPERPLAST® 400 is an injection plastic mold steel pre-hardened to a high level of hardness. It is delivered at a typical hardness of 125 kg/mm2. This steel is specially adapted for heavy-duty molds used for production of long series, for compression molds or when an improved wear resistance is expected. SUPERPLAST® 400 will be ideal where a high resistance of the mating plan surface is required and when the conventional 300 HB or even conventional high hard material cannot ensure adapted properties. SUPERPLAST® 400 exhibits processing aptitudes strongly improved compared to conventional steel W1.2711 or equivalent, heat treated to same hardness. This improvement mainly results from a new chemical balance. SUPERPLAST® 400, delivered at 350 to 380 HB, has excellent weldability, a better micro structural homogeneity and a much better machinability than conventional grades heat treated to the same level or even lower hardness. All injection molds demanding high mechanical properties: long series; high injection series; injection of reinforced plastics (glass fibers); wear problems; compression molds |
