1.Impact of carbon It can be seen from Fig. 1 and Fig. 2 that the toughness of steel decreases with the increase of carbon content, and the hardness increases. This is mainly because carbon not only strengthens the matrix in steel, but also increases the hardenability of steel. Although...

Chemical composition of cast low alloy bainite wear resistant steel shovel teeth of excavator
Carbon is the main element in steel and plays a decisive role in the matrix structure of steel. A small amount of carbon is dissolved in ferrite, and the rest exists in the form of cementite. Carbon is the main element of strengthening, but in order to reduce the...

Cast low alloy bainite wear resistant steel excavator shovel teeth
Most of the shovel teeth of roadheader work in the environment of high impact, high wear and high hardness, so the materials must have high impact toughness and high hardness. Bainitic steel has good comprehensive mechanical properties and relatively low cost, which has attracted much attention in recent years....

Advantages of wear-resistant parts of sand casting crusher
The wear-resistant parts of sand casting crusher are still very common in China, such as jaw plate, high chromium plate hammer, crushing wall, rolling mortar wall, etc., because in the crusher equipment, as a relatively large wear-resistant casting, the accuracy is not very high, especially for jaw plate, the...

Dual liquid pouring / mold transformation technology for wear-resistant castings
The bimetallic jaw wear-resistant castings were successfully wound by using the bimetallic liquid winding injection / transformation molding technology of wear-resistant castings. The composite casting method includes two process steps of “changing the upper mold” and “bimetallic liquid sparing injection”. The process adopts the winding injection mode of high...

Research status of wear resistant cast iron
1. Ordinary white cast iron Ordinary white cast iron can only be used in as cast state, and carbon atoms mainly exist in the form of Fe3C. The matrix structure of as cast ordinary white cast iron is pearlite or ferrite, i.e. ledeburite structure, and the hardness is about...

Effect of heat treatment process on bainitic Martian multiphase wear resistant cast steel
There are two traditional methods to obtain bainitic steel: (1) Isothermal quenching method: heat the steel to a certain temperature above AC1 or AC3 for austenitizing to obtain austenite structure, and then quench it to the medium temperature zone at a cooling rate greater than the critical speed. Heat...

Effect of microstructure of bainite martensite composite wear resistant cast steel
As shown in Figure 1, the types of bainite structure include upper bainite, lower bainite, carbide free bainite, granular bainite, quasi bainite, etc. The upper bainite is feathery and has obvious crystal trend. The carbides in the upper bainite are rod-shaped and distributed in parallel between the ferrite laths....

Effect of composition of bainitic Martian multiphase wear resistant cast steel
The chemical composition has a great influence on the mechanical properties and microstructure of bainitic Martian multiphase wear-resistant cast steel. The depressing effect of alloying elements on bainite phase transition temperature (BS) point and martensite phase transition temperature (MS) point directly affects the morphology and properties of bainite structure....

Four dimensional wear of wear resistant cast steel for lining plate of cone crusher
The photos of the conical crusher liner before and after use taken at the workshop site are shown in Figure 1. Figure 1A shows that the liner surface is clean and the polished part is flat and bright before assembly. From figure 1b, it can be seen that the...
