A prehardened mold steel (300 HB/32 HRC) for thick sections W1.2738 is a 300HB (32HRC) prehardened grade specially designed for plastic mold industry. Chromium, Molybdenum, Nickel and Manganese additions are optimized to have a fully martensite – bainite microstructure after quenching. The high nickel content (1%) is specially adapted to ensure a perfect homogeneity of structure and hardness through thickness even for thick blocks (up to 700 mm/28’’). The steel is melted in electrical furnace and refined with VOD or DH device. The cleanliness of the steel is guaranteed as well as the soundness. This makes the steel particularly well adapted for mold even when polishing or chemical etching are required for surface finish quality.
