4CR13 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.

Heat treatment


In a protected state, heat up to 780 ℃ and then cool to 650 ℃ in the furnace at 10 ℃ per hour and then cool in the air.

2.Stress elimination

After roughing, must be heated to 650 ℃, both hot 2 hours, slowly cooling to 500 ℃, and then cooling in the air.


Preheating Temperature: 600-850 ℃

Quenching temperature: 980-1050 ℃


High degree of polishing and high requirements of the internal mold, corrosion-resistant plastic molds, production, medical, food industry, and other products. S136 can be used with all molds, due to their special nature, more suited to the needs of special environments.
