GS-2311 use: GS-2311 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 needs of general purpose, die life die times of up to 50W
2311 2311 Pre-hardened plastic mold steel, mold steel, after heat treatment, machining and polishing performance is good, more suitable for EDM. Can be used for general manufacturing large plastic mold plastic mold and mold used.
Pre-GS2311 hard to 980-1080N/mm2 (30-34HRC) steel Features: This is P20 steel with 1.1% nickel, the steel surface to the center of uniform hardness, good cutting, EDM and polishing excellent performance, suitable for gasification hard chrome plating and titanium.
GS2311 uses: high demand for plastic molds, especially over 400MM thick of the molds.
:720-740 ℃ annealing and heat through insulation sufficient time, then cooling with the furnace to 600 ℃, then cooling in air, from hardness of approximately 240HB (highest).
Stress relief: heated to 600 ℃ in the protective gas furnace heat about 2 hours, then slowly cooled with the furnace.
Thermal quenching :840-860 ℃ after quenching oil, or 860-880 ℃ heat slightly higher than room temperature air-cooled immediately after tempering, the hardness from approximately 54HRC.
Tempering: Temper immediately after quenching, not less than 2-2.5 hours, cooled and then baked.
Forging :1050-850 ℃ furnace cooling
Annealing :850-900 ℃ air-cooled
