| Annealed hardness |
after Q+T, hardness 38-42HRC |
| Characteristics |
super clean, ESR manufacturing process age-hardened for uniformity of hardness throughout, even in heavy section
when welded, leaves no witness lines after re-aging
uniform grain structure with no pin holes, inclusions or hard spots
machines up to 20% faster than 30HRC P20 mold steels
never needs stress relieving, even after heavy maching
super polishability, even over welded areas |
| Applications |
clear lens molds |
| extremely critical diamond finish applications |
| molds requiring special EDM finish |
