Question 1: Looking for wear-resistant metal materials. Answer: According to your description, it is recommended that you use wear-resistant steel Mn13.
1. There are many types of wear-resistant steel, which can be roughly divided into high manganese steel, medium and low alloy wear-resistant steel, chromium-molybdenum silicon-manganese steel, cavitation-resistant steel, abrasion-resistant steel and special resistant steel. Grinding steel etc. Some general alloy steels such as stainless steel, bearing steel, alloy tool steel and alloy structural steel are also used as wear-resistant steel under specific conditions.
High manganese wear-resistant steel Mn13 is the best choice among wear-resistant materials that can withstand strong impact and high-stress material wear. There are two biggest characteristics of high manganese steel: first, the greater the external impact, the higher the wear resistance of its own surface layer; second, as the surface hardened layer gradually wears away, new work-hardened layers will be continuously formed. Mn13 has excellent wear resistance against strong impact wear and large stress wear, will not be broken during use, and has good machining performance.
2. Wear is a process that occurs on the surface of the workpiece. Therefore, in order to save costs, cheaper base materials can be used to make workpieces, and the wear resistance of steel parts under various types of wear conditions can be improved through surface strengthening, such as carburizing, carbonitriding, nitriding and other surface strengthening. Craftsmanship.
Question 2: What is the most wear-resistant metal material? The most wear-resistant metal materials are industrial materials used to solve complex wear problems. Take the nickel-tungsten alloy produced by Beijing Nemo Company as an example. Its hardness reaches above HRC70. It is mainly used in industrial valves and silicon powder transportation pipelines.
Question 3: What are the wear-resistant metal materials? Wear-resistant metal materials have the following categories:
1. Chromium carbide wear-resistant metal materials, such as: produced by Beijing Naimo Technology Co., Ltd. Chromium carbide wear-resistant steel plate.
2. High manganese steel wear-resistant materials, such as: knmn19cr2.
3. Tungsten carbide metal wear-resistant materials, such as: jp8000 spray tungsten carbide coating.
Question 4: What are the metal wear-resistant materials? According to the composition of metal wear-resistant materials, Beijing Naimo Company divides metal wear-resistant materials into the following five categories:
First, high manganese steel series: such as high manganese steel (ZGMn13), KNMn19Cr2 (patented) high manganese alloy (ZGMn13Cr2MoRe), ultra-high manganese alloy (ZGMn18Cr2MoRe), etc.;
The second is anti-wear chromium cast iron series: such as high, medium and low chromium alloy cast iron (Cr15MoZCu);
The third is Wear-resistant alloy steel series: such as medium, low and high carbon multi-component alloy steel (such as ZG49SiMnCrMo and ZG35Cr2MONIRe);
The fourth is ADI series
The fifth is each Composite-like or gradient materials and cemented carbide materials, KN ??nano-alloys (patented products): such as chromium carbide composite materials (Cr2C3=Q235), high-energy ion implantation tungsten carbide materials (WCSP), high-toughness cemented carbide (YK25. 6), KN999 nano alloy, etc.
Question 5: Are there any metal materials that are wear-resistant and high-temperature resistant? You didn’t say where the material is used or what the temperature is, so it’s not easy to choose.
The best metal that is resistant to high temperatures and wear is platinum (platinum), which is a commonly used material for torch heads.
If it is a common ordinary metal material, alloy steel containing molybdenum should be used for high temperature resistance, and alloy steel containing titanium should be used for wear resistance, such as 1Cr18Ni12Mo2Ti
Question 6: What Wear-resistant and impact-resistant metal materials are usually a mixture of iron and carbon. Manganese steel and Tungsten steel are divided according to the amount of carbon. Manganese steel is mainly used to withstand impact, extrusion, material wear, etc. Under harsh working conditions, the main form of damage is wear and tear, with partial fracture and deformation. Wear is divided into three types: friction and wear when the surfaces of metal components are in contact with each other and move; abrasive wear when other metal or non-metallic materials hit the metal surface; and erosion wear caused by the contact between flowing gas or liquid and metal. The wear resistance of wear-resistant steel depends on the material itself, and wear-resistant steel shows different wear resistance under different working conditions. Both the material itself and the working conditions determine its wear resistance.
Cast wear-resistant steel and wear-resistant steel are mainly austenitic manganese steel. Low-alloy steel that has been appropriately heat-treated under certain conditions also has good results. Graphite steel is used for lubrication and friction. Working conditions.
Wear-resistant high manganese steel is especially suitable for impact abrasive wear and high-stress grinding abrasive wear conditions. It is often used to manufacture ball mill liners, hammer crusher hammers, jaw crusher jaw plates, and cones. Impact-resistant and wear-resistant castings such as crusher rolling mortar walls and crushing walls, excavator bucket teeth and bucket walls, railway switches, track pads of tractors and tanks, etc. High manganese steel is also used in: bulletproof steel plates, safe steel plates, etc.
Question 7: What metal material is the most wear-resistant? Tungsten carbide is more wear-resistant
Question 8: What metal material is wear-resistant and compressive? Cheap metal materials include wear-resistant Hejia cast iron and GCr15 bearings Steel, etc.;
The more expensive ones include precipitation hardened stainless steel;
The best material is carbide.
Of course, non-metallic materials include ceramics and silicon carbide.
