Classification Of Alloy Steel Castings

In order to meet our different process requirements, alloy steel castings have different classifications. In fact, they are classified according to different classification methods. This article will introduce you to the total amount of alloying elements, which can be divided into several categories.

1. Low alloy steel castings are mainly used in manganese series, manganese silicon series and chromium series. Such as ZG40Mn, ZG30MnSi1, ZG30Cr1MnSi1 and so on. It is used to manufacture parts such as gears, hydraulic press working cylinders and hydraulic turbine rotors, while ZG40Cr1 is often used to manufacture important stress parts such as high-strength gears and high-strength shafts.

2. High alloy steel castings have special properties such as wear resistance, heat resistance or corrosion resistance. Such as high manganese steel ZGMn13, is a kind of anti-wear steel, mainly used to manufacture parts used under dry friction working conditions, such as the front wall of the grab bucket and the bucket teeth of the excavator, the crawler of the tractor and the tank, etc.; chrome-nickel stainless steel ZG1Cr18Ni9 and chromium stainless steel ZG1Cr13 and ZGCr28 have high corrosion resistance to nitric acid, and are mainly used in the manufacture of chemical, petroleum, chemical fiber and food equipment parts.

To sum up, alloy steel castings can be divided into the above two types according to the total amount of alloy elements. Here, users are reminded to choose according to the working environment in actual use.
