WEAR RESISTANT WHITE CAST IRON CR26
Anti-wear white mouth cast iron pipe is mainly used for the conveying of abrasive materials such as pneumatic and pumping slurry
Anti-wear white mouth cast iron pipe is a kind of wear-resistant pipe, mainly including wear-resistant straight pipe, elbow, tee, size head, square section, variable diameter pipe and other structural parts. This pipeline is especially suitable for conveying media with high hardness, fast flow rate and large flow rate, which will have impact, wear and corrosion on the pipe wall in the transmission process. Anti-wear white cast iron is the preferred material for manufacturing wear-resistant parts because of its high hardness, good wear resistance, impact resistance and toughness. In addition, anti-wear white cast iron also has good corrosion resistance and heat resistance, its surface dense oxide film covered by the erosion can effectively resist a variety of acid, alkali and salt and other chemical media, and can maintain stable performance in high temperature environment, suitable for the manufacture of wear-resistant parts under various high temperature conditions. Therefore, anti-wear white cast iron pipes play an important role in the industrial field, especially in environments required to resist strong wear and corrosion, and their applications are particularly widespread 12.
Chemical composition of ground-resistant white-mouth cast iron
The chemical composition of ground-resistant white cast iron usually includes a higher carbon content (about 2.8% to 3.6%) and a moderate amount of silicon (0.5% to 1.3%). In addition, in order to enhance its wear resistance and other properties, some alloy elements such as chromium, molybdenum, nickel, vanadium, boron and rare earth are often added. For example, the chemical composition of high chromium cast iron can reach high levels of chromium, while nickel hard white cast iron contains 4% to 6% nickel and about 3% carbon, while about 2% chromium is added to prevent graphitization. These ingredients make white cast iron with excellent hardness and wear resistance, suitable for high wear-resistant applications, such as manufacturing abrasive tools, cutting tools, etc.
Advantages of anti-grinding white mouth cast iron pipe
The advantages of anti-wear white mouth cast iron pipe are mainly reflected in its high hardness, good wear resistance, impact resistance, corrosion resistance, heat resistance and low production cost.
Because to its special chemical composition and process, anti-grinding white cast iron has the following remarkable characteristics:
High hardness and wear resistance: white wear resistant cast iron hardness up to HRC 58-62, its high hardness and good wear resistance make it the first choice material for manufacturing wear resistant parts. This property benefits from the special distribution of carbon in the matrix, which forms a high hardness.
Impact resistance and toughness: anti-wear white cast iron can withstand large impact load and stress, the carbide in its internal tissue can effectively absorb the shock energy, improve the toughness of the material, even under the condition of high strength impact can still maintain good wear resistance and durability.
Corrosion resistance and heat resistance: The surface of resistant white cast iron is covered with a dense oxide film, which can effectively resist the erosion of various chemical media such as acids, bases and salts. At the same time, in the high temperature environment, the anti-wear white cast iron can still maintain a stable performance, suitable for a variety of wear-resistant parts under high temperature conditions.
Lower production cost: compared with stainless duplex stainless steel, the production cost of anti-wear white cast iron is relatively low, which makes it has certain economic advantages, especially in the case of high requirements for wear resistance and limited budget.
In conclusion, anti-wear white cast iron due to its excellent physical and chemical properties as well
