Physical Properties
Heat Treatment Process
Hardening: Heat the steel evenly to 1000~1040°C until the whole section reaches temperature. Then quench in oil to cool.
Annealing: Heat the steel to 780~820°C, hold it well at temperature, and then let it cool slowly inside the furnace.
Tempering: Heat the steel uniformly, hold it at the selected tempering temperature, and then allow it to cool in still air.

| Hardness (HRC) | 49 | 47 | 46 | 46.0 |
Application Fields
Molds for chemically aggressive plastics and plastics containing abrasive fillers, sliders, profiles, mold inserts, molds and extruding tools for corrosively acting plastics such as PVC and other plastics.
