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.
Our company have introduced large-sized vertical saw machines, horizontal saw machines, milling machines, grinding machines and other advance equipments, we can export our products by wholesales and retail sales, whole plate or strip is available.
So we can provide below service:
A. Steel plates: Cutting by bandsaw machine, milling, heat
treatment, etc
B. Round bars: Cutting by bandsaw machine, peeling, grinding and
turned, heat treatment, etc
