Nitrided Ferro Chrome, LC FeCr

Q:Detailed comparison of cemented carbide with diamond properties: At present, the drill bit above the 981 offshore oil platform, which is being drilled in the South China Sea, is a typical diamond tool, which requires a high level of technology.At present, due to the rapid development of the diamond industry, a lot of new diamond tools are being developed at a very fast speed, some of which are far superior to the traditional cemented carbide tools in performance. With the development of the times, the depletion of metal resources, I believe that more than 80% of carbide applications will be replaced by diamond tools. As a green energy, diamond is showing great vitality.

Q:The difference between cemented carbide and tungsten.: Tungsten steel (hard alloy) with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.Also known as tungsten steel, hard alloy, refers to the sintering of the composite materials containing at least one metal carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, tantalum carbide is tungsten steel common components. The grain size of the carbide component (or phase) is usually between 0.2-10 microns, and the carbide grains are bonded together with metal binders. Binder usually refers to metal cobalt (Co), but for some special purposes, nickel (Ni), iron (Fe), or other metals and alloys can also be used. The composition of an undetermined carbide and bond phase is called "grade"".

Q:What are the types, codes, and range of application of cemented carbides?: I am also engaged in carbide industry, different grades (there are ISO brand, there are some domestic brands, and some even use the manufacturer's own brand) on behalf of the composition and use of the barrier.. Because of the wide variety of brand names, the average person will only involve one or several specific industries, and there is no need to know all the code names and their detailed performance... Therefore, we usually produce or recommend the brand (code name) according to the performance and use of the customer..Customers are generally in order before provide you with detailed performance parameters, although not in the factory name brand in different, but according to the performance parameters of the still commonly found in different plant in the corresponding or similar grades, but some brands of blade complex, and complex composition, tell you some properties can not be done with the original brand as like as two peas.. In the blade field, there is still a big gap between China and foreign countriesAlso, due to the development of hard alloy, grade ISO has lost his original meaning of..K20, K30, K40, K05.. And so on, people don't seem to know what they want, if my client told me that these ISO grades, I basically have to provide him with detailed performance parameters..Friends, you are in that industry, our company mainly engaged in geological and mining products (ball gear, drill chip, pick, engineering, knife, shovel snow tooth.Etc)

Q:There are three kinds of cemented carbides, of which tungsten, cobalt and titanium are brittle cemented carbides?: Cemented carbides are classified into tungsten, cobalt, tungsten, titanium, tungsten, titanium, tantalum and cobalt. Tungsten cobalt carbide knife with: YG6, YG8, YG8N and so on, such carbide cutting tools for processing non-ferrous metals, stainless steel, cast iron and other materials;Tungsten carbide hard alloy knife has: YT5, YT15, etc., this kind of carbide cutting tools for processing steel and other tough materials;Tungsten, titanium, tantalum, cobalt carbide knife with: YW1, YW2, YS25, WS30, etc., this kind of carbide cutting tools for processing heat-resistant steel, high manganese steel, stainless steel and other difficult materials.

Q:Where does Tianjin sell yt30 carbide tool?: Now there are the same, express, everything is not afraid. I am the agent of Zigong the Great Wall brand cemented carbide, quality assurance, definitely authentic.

Q:What is a hard alloy mixture?: Is used to suppress the material, after the formation of reference materials after. Use with a variety of molding materials

Q:Carbide cutting insert: These brand knives are usually Zhuzhou diamond brand and Zigong the Great Wall brand. Other brands are also located in these areas.

Q:Can hard alloy be made into barrel?: No, hard alloy too hard too fragile, not processed, there should be a rifle barrel, it is difficult to machining.

Q:What is the heat treatment process of cemented carbide?: To put it plainly, that is, hardening of cemented carbide, that is, heating to a certain temperature, insulation for a certain period of time, and then suddenly into the inert gas, so that it suddenly cooling.. The same as steel quenching. After quenching generally tempered, to eliminate the stress produced by quenching, it is mainly to change the bonding phase components, that is, the organizational structure, improve the strength of cemented carbide, hardness and comprehensive performance

Q:Chengdu which has carbide scrap acquisition point?: Bars of 75000 yuan / kg (Fu Xujian) Zhejiang Zhoushan self-employed waste tungsten 150-200 yuan / kg, Hebei Hengshui Gucheng County Sindh rare metals tungsten tailings 100-300 yuan / ton Guangzhou lechran gold bars 1200 yuan / kg, Zhengzhou Zhengzhou Hongsen tin small PCB tungsten steel drill 160-190 yuan / kg in Zhejiang Taizhou
