Daido multi-purpose plastic mould steel with High toughness, Good anti-corrosion and Excellent polishability
Annealed to HB229(max), surface hardness of HRC46-52 can be attained with proper heat treatment
High Toughness – almost the same impact value of that of SKD61 or 2-3 times of that of original SUS 420J2.
Excellent polishability – PAT868S could attain to mirror polishing level, which is similar to SUS420J2 ESR material.
Good Anti-corrosion – under acidic environment, PAT868S shows comparable corrosion resistance with SUS420J2 and much better than SKD61 after all are tempered at high temperature.
Suitable for making the special plastic moulds with the adoption of rapid heat and cool technology.
Good for the through-hardened plastic mould insert and sliders with the complicated structure and fine surface finish.
