heat treatment jis nak80 alloy steel material

A brief introduction of mold steel LKALLOY

May 13, 2019 · The steel material for first and second class mold that can be heat treatment and hardness can be up to HRC50 or so, otherwise the mold are easy to wear and injection molding product qualification rate is poor, so the choice of steel not only have better heat treatment performance but also have good cutting performance in the state of high hardness, that depends other problem should to be AISI 4130 Steel - 25CrMo4 - JIS SCM430 - GB 30CrMo If the temperature is 300-350 on the heat treatment processing, get the flake is a tendency. It is medium-Carbon alloy steel which can be oil quenched to attain a maximum as-quenched hardness of approximately 48HRC. Its hardenability is significantly higher than that of the carbon-molybdenum(40xx) grades. 4130 Alloy Steel Applications

Compared with the conventional steel materials of other companies, the machining time for our new Because of special alloy elements in our HP series plastic mold steels, one can obtain better etching workability, polishing workability and weldability than in many other products. HEAT TREATMENT NAK80 Plastic Mold Steel Plate Ningshing Special-SteelLow alloyed Presipitation hardening steel, with good comprehensive mechanical properties, high hardenability, convenient heat treatment, small deformation after heat treatment, good polishability. This material also has good nitriding, electrical machining, welding, and pattern marking performation. Properties and Applications of NAK80 plastic mould Steel Jun 24, 2020 · NAK80 plastic mould steel, a Ni Al Cu precipitation age-hardening steel, is characterized by high polishability. NAK80 plastic mould steel is sulphurized to give the steel good machinability, mirror finish and electrical discharge machinability, with good The weldability of the welded part of the hardness first decreases, and after the aging treatment and air cooling at 500°C × 5 hours after
