Q: Carbon steel valves in Baidu LibraryThe temperature can reach 425 degrees, is not without welding carbide seal, who has no detailed material ah?,: This 425 DEG C is the limit temperature of ASTM A216: -30 DEG C - +425 DEG CBut if the sealing surface of rice now is PTFE, it can be as high as +80 degrees centigrade. If the PTFE material is good, it can reach +150 centigradeTherefore, the body material is carbon steel, only that the valve body of the temperature range of this materialLook at the inside of the valve,For example, cryogenic carbon steel in LCB, ASTM, A325 can reach -46 degrees --+340 degrees centigradeHowever, if the sealing surface of your body is the sealing surface of plain carbon steel, the temperature range of this carbon steel valve is only the temperature range of the ordinary carbon steelIf you say that now is the carbon steel valves used in the sealing surface of the safety valve, you must need welding hard alloy (STL or D series, etc.) should have strong hardness of hard alloy after treatment, impact resistance.Depends on your flow channel medium, if it is high temperature, it is best to use 316, and so onThe use of valves is a combination of considerations

Q: Detailed comparison of cemented carbide with diamond properties: Hard alloy is a metal, usually refers to the number of tungsten carbide hard alloy components, there are many brands, such as YT YG series, this is found, it is mainly used as the traditional machining industry, a cutter head, tools, etc., our common lathe tool tip is above the hard alloy. The largest hard alloy base China in Hunan Zhuzhou tungsten group, a few years ago by Minmetals acquisition. Diamond is a non-metal is allotrope of carbon, he is by far the highest hardness of substances found in nature. Synthetic diamond, also known as industrial diamond, has developed rapidly in China in the past ten years. Its total output has accounted for more than 90% of the total amount of the world. With diamond related diamond tools, mainly used in the field of drilling, cutting, grinding, polishing, grinding, geological, stone, construction, industrial processing, precision instruments, aerospace, electronics, also known as super abrasive, and he (ordinary abrasive corundum and silicon carbide) called industrial teeth "plays a vital role in the economic development of Chinese.

Q: What materials are ZK20 cemented carbides processed?: ZK20 belongs to the K hard alloy blades can car many materials, such as: wrought iron steel low alloy cast iron high alloy cast iron ductile cast iron Aluminum Alloy hard plastic

Q: What is hard alloy grinding?: Its scope of application and the artificial diamond plays a complementary role. Cubic boron nitride wheel grinding of steel parts the efficiency ratio of corundum wheel to nearly a hundred times, five times higher than the diamond grinding wheel, but less than the diamond grinding of brittle materials.The diamond grinding wheel than boron carbide, silicon carbide, corundum and other general grinding blade grain made of sharp corner, small abrasion, long service life, high productivity, good processing quality, but the price is expensive, is suitable for the grinding of hard alloy, ceramic, semiconductor and other high hardness brittle hard processing material

Q: What are the meanings of cemented carbide codes, such as YW, YS30, YN10?Which company made its own brand? What is the composition?: Hard alloy is one of the people familiar with the tools and materials, it is very difficult to weld by hard metal carbides (we, Tie) of powder metallurgy with CO, MO and NI as sintering binder. Its mechanical, physical and mechanical properties depend mainly on the kinds of metal carbides, properties, quantities, grain sizes, types and components of binders.In cemented carbides, the proper addition of Tie increases the content of hard Tic, and the higher the hardness of the alloy. The more the content of cobalt in the bonding phase, the lower the hardness of the alloy. Therefore, the hardness of We-Tie-eo alloy is higher than that of We-eo alloy. The hardness of We-eo alloy can be increased by adding Tae or Nbc. The higher the hardness of the cemented carbide, the better the wear resistance, but the lower the strength (bending), and the addition of Tac will improve the blade strength, while strengthening the blade resistance to fragmentation and breakage, fatigue strength also increased. Generally, the higher the hardness, the lower the toughness. In China's Cemented Carbide standard YB850-75, most carbide grades are We-Co (YG) and We-Tie-Co (YT) two.Domestic hardness alloy grade control: GB, brand ISO, P10, P20, M10, M20, K01, K10, K20, K30, domestic uniform brand YT15, YT14, YT5, YW1, YW2, YG3, P30, YG6x, YG6, YG8

Q: What are the advantages of carbide V-CUT knives and diamond V-CUT knives?: Hard alloy cutter V-CUT V-CUT also known as tungsten steel knife, V-CUT knife is a highly cost-effective high quality, the overall use of hard alloy is refined, the hard alloy is a kind of tungsten cobalt powder by formula + mixture by pressing sintering of cemented carbide wafer using high quality carbide hard alloy, and then by the advanced precision grinding machining the tool made.Diamond cutting tools are relatively hard and have a hardness of 8000HV.

Q: Material properties of Cemented Carbides: Hard alloy with high hardness of refractory metal carbides (WC, TiC) micron powder as the main ingredient, with cobalt or nickel (Co) (Ni), molybdenum (Mo) as the binder, powder metallurgy products in vacuum furnace or hydrogen reduction sintering furnace. IV, B, V, B, VI, B group of metal carbides, nitrides, boride, etc., because of hardness and melting point is particularly high, collectively referred to as cemented carbide. The structure, characteristics and application of hard gold content are described with carbide as the key point. IV, B, V, B, VI, B group metals and carbon formed in the metal type carbide, because the carbon atom radius is small, can be filled in the gaps of the metal lattice, and retain the original lattice form of metal, forming interstitial solid solution. Under appropriate conditions, such solid solution can continue to dissolve its constituent elements until it reaches saturation. Therefore, their composition can change in a certain range (such as the composition of titanium carbide in TiC0.5 ~ TiC changes), chemical formula does not conform to the rules of valence. When the dissolved carbon content exceeds a certain limit (such as titanium carbide in Ti: C=1: 1), the lattice type will be changed, the original metal lattice metal lattice into another form, then the interstitial solid solution called interstitial compounds.

Q: What are the common kinds of cemented carbides?: Cemented carbide is a hard particle of refractory metals (tungsten, tantalum, titanium, molybdenum, etc.) that is mixed with one or more iron elements (cobalt, nickel, or iron), pressed and molded, and then sintered. Types and properties of cemented carbides: (1) classification and grade of cemented carbides. Tungsten carbide cobalt carbide is mainly composed of tungsten carbide (WC) and binder cobalt (Co). The brand is from "YG" ("hard cobalt" Pinyin prefix) composition and percentage of average amount of cobalt. For example, YG8 is a tungsten cobalt carbide that represents an average WCo = 8% and the remainder is tungsten carbide. Tungsten carbide cobalt carbide is mainly composed of tungsten carbide, titanium carbide (TiC) and cobalt. The grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide. For example, YT15 represents an average WTi = 15%, while the others are tungsten titanium cobalt carbide with tungsten carbide and cobalt content. The tungsten titanium tantalum (NB) hard alloy is the main component of tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. This kind of hard alloy is also called universal cemented carbide or universal hard alloy.

Q: What is the difference between hard alloy steel and high speed steel?: 3, hardness is not the same: cemented carbide hardness, especially at high temperature hardness, but high-speed steel toughness better4, can withstand the cutting speed is not the same: due to the red hard high, can withstand higher cutting speed, and high-speed steel is now not high speed
