3Cr2Mo
Standard: GB / T 1299-1985
Hot work tool steel, is the introduction of P20 in the United States Department of the carbon Cr-Mo steel, plastic mold. For the production of plastic mold and die casting low melting point metal mold material. This steel has good cutting and mirror polishing performance.
How to use:
P20 pre-hardened to 285-330HB (30-36HRC), and Sweden 618 German GS-2311 status rather, can be directly used for molding processing, and has good dimensional stability characteristics, pre-hardened steel can meet the general purpose demand, die life die times of up to 50W
Features:
● pure steel vacuum degassing refining process for polishing or etch processing requirements of the plastic mold.
● Pre-hard state supply without heat treatment can be used directly in the mold, shorten the construction period.
● by forging rolling processing, compact structure, 100% ultrasonic inspection, non-porous, needle defects.
Uses:
● thermoplastic injection molding, extrusion die.
● thermoplastic blow molding.
● Overloading the main components of the mold.
● Cold structural parts.
● commonly used in the manufacture of television chassis, washing machine, refrigerator shells, buckets and so on.
