plastic mold steel

1.2311 steel, German mold steel, the steel is produced through "ultra-pure" process, pre-hardened, showing a high degree of microscopic purity and excellent homogeneous structure, excellent polishing and photo-etching characteristics. After heat treatment, the processing and polishing performance is good, it can be nitrided, suitable for surface treatment such as chrome plating, the material has uniform hardness (up to 400mm thick), good toughness, and good mechanical processing performance. The gold structure is martensite and bainite.
