Detailed Description
Principal Design Features
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.never needs stress relieving, even after heavy maching, super polishability, even over welded areas .Very good workability and mirror polishing property, suitable for thermoset molding of general resin.
Pre-hardened to HRC36-43, ,heat treatment and deformation could off.
Solution treatment and heat treatment to HRC36-43.
Applications
Used for high precision mirror plastic mould, high appearance home electronic plastic mould, clear lens molds.
extremely critical diamond finish applications, molds requiring special EDM finish
