S136 Mold Steel Advantages

S136, a plastic mold steel, stands out for its superb corrosion resistance and remarkable production attributes. Even after extensive use, the cavity surface retains its pristine smoothness. Furthermore, molds made from S136 require no special protection when operated or stored in humid environments.
1. Pure & Precision mirror polishing
2. Competitive pricing in the market
3. Exceptional corrosion resistance quality
4. Convenient heat treatment for quenched & tempered steel without deformation
5. Effortless welding process

Heat Treatment

1. Annealing
In a controlled environment, heat to 780 ºC then gradually cool to 650 ºC inside the furnace at a rate of 10 ºC per hour, followed by air cooling.
2. Stress Elimination
Following rough machining, heat to 650 ºC, maintain for 2 hours, then slowly cool to 500 ºC, and finally cool in air.
3. Hardening
Preheating Temperature: 600-850 ºC
Quenching Temperature: 980-1050 ºC

Application

Designed for applications demanding high levels of polishing and stringent internal mold requirements, S136 is perfect for corrosion-resistant plastic molds used in production, medical, and food industry sectors. Its versatility makes it suitable for all molds, particularly those in specialized environments.
