Description

S136 Mold Steel material by electroslag melting smelting with good cast optical activity (mirror processing) good wear resistance and toughness at high temperature with good plasticity because of its high chromium content (13.6%) so its corrosion resistance is excellent, pre-add hard corrosion-resistant mirror mold steel S136 is a mirror rust-proof mold steel.

S136 mold steel with excellent corrosion resistance has been widely applied in the mold industry. However, in order to meet the increasing demands of injection products with complex structure and high quality, selective laser melting (SLM) as a novel manufacturing method is chosen due to its rapid fabricating parts with complex geometric shapes. Further, it is essential to enhance their hardness and wear property to prolong the service life of the injection mold.
