Application

Chrome is always used to improve the antioxidation and corrosion resistance of steel to make the surface of steel after it is oxidized to form strong adhension oxide film. Then it stops being oxidized or decelerates being oxidized.Micro-Carbon ferro chorme is applied to making stainless, acid-resistant steel and heat resistant steel.

Low carbon Ferror chrome

Q: What are the cemented carbides?: Tungsten cobalt carbideWC cutterThe main ingredients are 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, a tungsten cobalt carbide represented by an average WCo=8% and the remainder of tungsten carbide.

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 are the main items of cemented carbide production process and finished products inspection, as well as the price of testing equipment, equipment and equipment?!! Please experts advice and answer, the younger brother will be grateful!!!!!!: Fluorescence detection: fluorescence detectorScanning electron microscope: SEM scanning electron microscopeXRD: XRD testElectron microscopy: TEM projection electron microscopyMy school student, brother, I speak not all, you should all do so, detection cost is not expensive, but the equipment to buy it, not tens of millions of nabuxialai, and equipment is not the same.

Q: What is the specific gravity of cemented carbide?: The carbon content of WC theory is 6.128% (atom 50%). When the carbon content of WC is greater than the theoretical carbon content, the free carbon (WC+C) appears in WC. The existence of free carbon leads to the growth of WC grain around it, resulting in uneven grain of cemented carbide. General requirements of tungsten carbide compound carbon high (more than 6.07%), free carbon (less than 0.05%), the total carbon depends on hard alloy production process and use scope.Under normal circumstances, the total WC carbon content in the vacuum sintering process of the paraffin process is mainly determined by the combined oxygen content in the block prior to sintering. An oxygen content should be increased by 0.75 parts of carbon, that is, WC total carbon, =6.13%+ oxygen content,% * 0.75 (assuming the sintering furnace is neutral atmosphere, in fact, most of the vacuum furnace is carburizing atmosphere, and the total carbon content of WC is less than the calculated value).At present, China's total carbon content of WC is roughly divided into three kinds: paraffin process, vacuum sintering, the total carbon content of WC is about 6.18 + 0.03% (free carbon will increase). The total carbon content of WC for hydrogen sintering of paraffin process is 6.13 + 0.03%. For rubber process, WC total carbon =5.90 + 0.03% is used for hydrogen sintering. The process is sometimes interleaved, so the determination of WC total carbon should be based on specific circumstances.

Q: Is there a material that is more wear-resistant than cemented carbide and has a relatively low cost?: If it is numerical control tool, it is more wearable than cemented carbide: ceramic, CBN, diamondAmong them, the lowest price of ceramics, diamond prices are highest

Q: Explain from the materialGeneral modelIf you buy itWhat parameters are provided?: Tungsten is on the hard alloy with tungsten carbide as the main (academic called tungsten based alloys), we called the daily hard alloy is usually tungsten based alloys, namely tungsten steel.There is another type of cemented carbide called titanium based cemented carbide, commonly known as "cermet"Buy it to shape (such as rods, blade), size and material (on behalf of the main chemical composition and particle size, but apart from a small number of national standard grade, most of them are the enterprise's own brand), and if you need special requirements (such as with cooling hole two 30 degrees within the spiral angle).

Q: What is steel bonded carbide? What are its characteristics?: Steel bonded carbide in steel bonding, with carbide (mainly titanium carbide, tungsten carbide) do hard phase composite material manufactured by powder metallurgy method. The microstructure is fine hard phase dispersed evenly distributed in the steel matrix (for steel bonded hard alloy mould substrate is mainly used chromium, molybdenum and vanadium in high carbon alloy tool steel or high speed steel).

Q: Carbide products which are used more?: Sealing rings in the sealing industry, mould industry, machine tools, milling cutters, drill bits in the mining industry, and armor piercing shells in the army, etc.

Q: What is the difference between the raw and recycled materials of cemented carbides? The more specific, the better: Raw raw materials are raw materials, recycled materials have been used, and then recycled and re produced, raw materials than recycled materials used, and more pure materials.

Q: 5 meters long hard alloy bars, where are they sold?: This should be hard to buy. You can call Zhuzhou diamond carbide group. If they don't, then there's no chance of it
