Aluminum Long Lasting And Durable P20 Mold Steel Plate For Automobile Industry

P20 Mold steel plate has many excellent properties. In the pre-hardened status, the mold can be processed without any heat treatment. Which cut down the running period and improves efficiency. After it has been processed through the forged, 1.2311 steel becomes dense. Then it can pass the 100% ultrasonic test. And after the test, there will be no pores left and no defect. And it also is called din 1.2311 and scm4 steel. P20 tool steel chemical composition and more information as below

P20 steel application:
P20 steel is used to make thermoplastic molds, extrusion dies, injection molds and die casting dies. And can also be used to make main components of heavy-duty mold. In addition, it also be used to produce cold structural parts, tv cases, washing machines, inner casings of refrigerator and buckets. Of course, 1.2311 steel can also be used to make bumper dies for automobiles or structural components of cars. 1.2311 steel has very good hardness and plasticity. So it can be used to make a variety of molds.

The method of use:
1.2311 steel has been pre-hardened to 285-330 hb(30-36 hrc), which can be used directly for mold making and process. It also has the characteristics of good dimensional stability. Just pre-hardened steel can meet the needs of the industry. The die life can reach 50 w mode times.
