Daido Steel - PAT868S
Daido multi-purpose plastic mould steel with High toughness, Good anti-corrosion and Excellent polishability

Delivered Hardness:
Annealed to HB229(max), surface hardness of HRC46-52 can be attained with proper heat treatment

Chemical Content(%):
Cr-Mo type

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.

Major Application:
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.
