HS 2738 Plastic Die Steel


HS 2738 is modified pre-hardened mirror plastic mold steel. Key technologies of alloy composition optimization and organization control ensure that the module has high hardness uniformity, excellent polishing performance and processing performance at the largest cross-sectional size. It is a new generation of super-large cross-section pre-hardened plastic mold steel.
