| Introduction | 2312 pre hardened large plastic mold steel, 2312 steel material hardness is uniform, good polishing performance, good machining performance, pre hardened state, can be processed directly, cutting ability is increased than 2311, wear resistance is increased than 2311, supply state: pre hardened state. |
The preheating temperature is 500 ~ 600 ° C, the quenching temperature is 840 ~ 880 ° C, and the holding time is 30min (the mold must be quenched in protective atmosphere to avoid oxidation and decarbonization). Oil cooling, cooling to 50 ~ 70 ° C, tempering immediately.
The tempering holding time is determined by the thickness of the workpiece every 25 mm for 1 h, at least 2 h. Tempering temperature 180 ° C / 200 ° C/
300 ° C / 400 ° C / 500 ° C / 600 ° C, hardness 52hrc / 51hrc / 48 HRC / 46hrc / 42hrc / 34hrc.
Induction hardening
The surface hardness of the steel can be increased to 50HRC by flame or induction hardening, and then air-cooled after hardening. General quenching medium can be used for small module, and tempering should be carried out immediately after hardening at 180 ~ 200 ° C.
3.Application1.Large long life plastic injection mold, such as home appliances, computer shell mold.
2·Extrusion die for thermoplastic
3·Blow mold
4·Molding tools
5·Structural parts4.Our ServiceA. Steel plates: Cutting by bandsaw machine, milling, heat treatment, etc
B. Round bars: Cutting by bandsaw machine, peeling, grinding and turned, heat treatment, etc
C. Ultrasonic testing and hardness testing 5.Feature1.Vacuum degassing refining processing steel purity, suitable for polishing or etch processing plastic mold.
2. In pre-harden state delivery, no need for heat treatment can be directly used for mold processing, shorten the construction.
3. After heat treatment machining and polishing performance is good, the nitriding treatment, can be suitable for chrome plating surface treatment, such as material is the qualitative hardness is uniform (400mm thick), good toughness and good machining performance.
4.Good hardness uniformity and polishing property, good machining properties.
5.Good integral mechanical performance under high temperatures.
6.Good heat-resistance and fatigue-resistance.
7. Pre-hardened to HRC30-36 can be directly used for mold processing, shorten the construction period. 6.
