Calibration of leaving factory: Pre-harden until it is 1000-1100N/ mm2(31-35HRC).
Characteristic: This steel can reach to31-35HRC after heat treatment. It is easy to process and polish. The content of chrome reaches 16%. With the excellent performance of being anticorrosive, it is more effective to PVC products, much easier to reach the cleanness of mirror surface.
Use: It is adapted for any plastic mould that contacts with chemical matters, transparent plastic product or any mould for corrosive products.
Forging: Forge it from 1050℃ to 850℃ and then back to furnace to cool it slowly.
Anneal: Cool to 800-850℃ in air or cool to 600℃ in furnace. The hardness can reach to 285HB.
Quenching: Cool to 1000-1050℃ in oil or in air.
Backfire: Back fire immediately in 600-700℃ or 170-210℃ after quenching. The time can not be less than 2-2.5h.
Welding: It is allowed to weld but as less as possible.
