HPM38 die steel was 13CR MO Department of containing stainless steel, specially manufactured good solution corrosion resistance, therefore, best suited to the requirements of high hardness and high corrosion resistance requirements mirror the plastic mold, and, HPM38 thermal dimensional changes small, suitable for precision heat treatment. HPM38 Japan Hitachi metal plastic mold steel, super mirror stainless steel, excellent mirror-polished, corrosion resistance and wear resistance, heat deformation, corrosion mirror finish steel, with hardness 50-55HRC , made of specially melting.
Steel properties HPM38 13 chrome molybdenum stainless steel, specially manufactured dissolved, and therefore most suitable for high hardness and corrosion-resistant mirror requirements for high plastic mold. And it is a very small thermal deformation, it is also suitable for precision heat treatment. In addition, erosion is good, very favorable for mold maintenance. Mirror processing is very good, with more than SUS420J2 better abrasion resistance, no chrome. Smaller abnormal heat treatment is most suitable for precision mold. Delivery of pre-hardened state, it can be used immediately.
