1.2083 Hot Rolled Plastic Mould Steel Round Bar With Corrosion-resistant
Introduction:
Grade1.2083 / 420 mold steel has good optical properties and mirror finishing properties after smeling by electroslag heavy soluble cast.
It has good abrasion resistance and good toughness high temperature plastic because of the high chromium content, so its excellent corrosion resistance, pre hardened corrosion mirror mould steel grade1.2083 / 420 is mirror steel against corrosion.

Applications:
1,Used as a high hardness and high abrasion resistance of hot oil pumps, valves, valves, bearings, medical equipment, springs and other parts.
2, production of PVC molds
3, abrasion resistance and filling mold, including hot and hard plastic mold, long-life mold, such as: disposable tableware mold
4, production of optical products, such as cameras and sunglasses, medical containers, laser discs and other products.
Advantage:
1, It is a kind of plastic mould steel that has excellent corrosion resistance and excellent production characterisitc.
2, It can be operated or stored in a wet environment without special protection.
3, This mould steel is not corrorded by cooling water, because there is a certain cooling cycle and also increase the service life.
