1. Nantong Hanrui Industrial Co., Ltd. was founded in 2007 with total area of 25000 m².

2. Our company possess large volume of natural vanadium resources .

3. Now our company has 40 sets of the advanced alloy production equipment.

4. The annual output of VNis 2400MT and 2000MT high purity vanadium.

Advantage for vanadium nitride

advantage	reason
Grain refinement and strengthening	Compared with VC, VN is better for the separation of V(C,N).
Reduce vanadium and lower cost	V(C,N)will cost fewer vanadium than that of VC, and this could reduce 40%, compared with Ferro-Vanadium.
Improve weldability, notch ductility and forgeability.	Use less carbon and less alloy addictive agent could reach the same strength level.
Effectively strengthening various carbon steel.	When temperature reach 1050 degrees Celsius, V(C,N) will have high solubility in austenite. Vanadium nitride work effectively in high, medium and low carbon steel.
Stain aging and shaping loss	Through choose Nitrovan 7 or Nitrovan 12, the proportion of V and N could be selected, avoiding nomadic nitrogen.

Fine Quality Fecr Alloy For Steelmaking

Q: MIG and TIG welding of cobalt base carbide and medium low carbon steel, respectively, using copper wire and stainless steel wire. What kind of corrosive liquid should be used in the welding seam to be metallographic?MIG+ copper welding wire, MIG+ stainless steel wire, TIG+ stainless steel wire: Cobalt based alloys are cobalt, which contains a considerable amount of nickel, chromium, tungsten, and a small amount of alloying elements such as molybdenum, niobium, tantalum, titanium and lanthanum, and occasionally contains an alloy of iron. According to the alloy composition is different, they can be made of wire for hardfacing powder, thermal spraying, spray welding process, can also be made of casting and forging and powder metallurgy.

Q: What brand of carbide is used in woodworking tools?: Carbide YS2T: is used for low speed roughing and milling of heat resistant alloys and semi finishing of titanium alloys, stainless steels, and low alloy steels. Carbide YL10.2: has high flexural strength and good wear resistance, used in low speed rough car and milling heat-resistant alloy, titanium alloy, also can be processed glass fiber reinforced plastic, making PCB micro drilling and so on. YG3/YG6: is suitable for hard alloy cast iron, nonferrous metals and their alloys and non metallic materials during continuous cutting fine cars, semi refined car, suitable for small section iron fine car, and can be used for the coarse thread, steel, nonferrous metals, wet lubrication tensile alloy wire and non metal wire drilling etc..

Q: Can CBN wheels grind cemented carbide? Why?: Cubic boron nitride grinding should not hard alloy and non-metallic hard materials in grinding, high temperature, CBN in alkaline aqueous solution will produce a chemical reaction, CBN wheel can be decomposed in 300 DEG C in alkaline solution, can trace decomposition in boiling water, the crystal grains were damaged, so the grinding, can only use oily the cooling liquid, and can not use water-based coolant.CBN wheel grinding for mild steel, heat-resistant steel, high hardness alloy steel precision grinding and finish grinding. The special steel products such as tungsten, molybdenum and cobalt high speed steel, alloy steel, high-speed steel with special grinding, super finishing machining of heat-resistant parts, and other steel quenching workpiece grinding line.

Q: How many models are there? 10Because we want to purchase carbide milling cutters, we would like to know the classification methods and the characteristics of various types of carbide at home.Some people say that Zhuzhou is best, Nanchang, Fujian, Longyan in turn. But there are many factories in a region. How can you say which is good and that is not good?Do you have a YL model?: Overall, Zhuzhou cemented carbide works, Shanghai alloy materials factory, Zigong cemented carbide plant, new carbide knives are good. But the single pair of milling cutters is not clear! There is no YL!

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: Have seen many of the whole alloy cutting tool brand, I would like to ask, the global overall alloy cutting tool brand, which have quality and price advantage, I want to be a cheap brand regional agent!: Brands have Swedish shandeweike, Israeli American Kenna; in accordance with Scafa, second tier brands are MITSUBISHI, Chinese Zhuzhou diamond brand, German Walter, three line brand in Taiwan, South Korea and China's Zigong Great Wall, Zhuzhou Jingcheng diamond card card, Qinghe etc. many, this is not the only one. In short, hard alloy cutter is very complex do you want to say, the light is not enough to know the brand, but also need to learn a lot of tools and machining knowledge of it. Finally, I wish you success!

Q: We'll drill on the stainless steel column. Which bit is better?: High cutting force and high cutting temperatureThis kind of material has high strength, large tangential stress and large plastic deformation during cutting, so it has great cutting force. In addition, the material has a poor thermal conductivity, which results in the increase of cutting temperature, and the high temperature often concentrates in the long and narrow area near the cutting edge of the tool, thus speeding up the tool wear.Serious work hardeningAustenitic stainless steel and some high alloy stainless steel is austenite, high work hardening tendency when cutting, usually plain carbon steel several times, the tool in hardening region cutting, shortening tool life.Easy to stick the knifeBoth austenitic stainless steel and martensitic stainless steel exist in the process of chip toughness, cutting temperature is very high. When the tough chip flows through the rake face, the bonding, welding and other sticking phenomena will occur, which will affect the surface roughness of the machined parts. ??Tool wear acceleratedThe materials generally contain high melting point elements, large plasticity, high cutting temperature, so that the tool wear faster, sharpening and changing knives frequently, thus affecting the production efficiency and improving the tool cost.Mainly to reduce the cutting line speed, feed. With special processing stainless steel or high temperature alloy cutting tools, drilling, tapping the best internal cooling

Q: What kind of industry can use carbide?: Blade material used in mechanical processing

Q: How can I buy carbide die on the Internet? Who can help?!: The mould made from the same carbide alloy made from Zhuzhou will not be sold.

Q: I want to process more hard stainless steel, with YC45 this type of carbide knife can do? Where can I buy authentic, know the friend told me, thank you: YC45 hard alloy cutter is made of tungsten alloy tool. The main alloy components are tungsten and cobalt, which have better wear resistance, good weldability, and good effect in processing solid wood, redwood and so on. Is a widely used, stable quality alloy, can also be used for cutting tools of various metals. Tungsten alloy containing tungsten 18%, hardness of Vivtorinox 10K, second only to diamond. The product has the characteristics of tungsten steel is not easy to wear. Commonly used in lathe tool, drill bit, glass knife head, tile cutter, hard but brittle annealing.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal. 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. Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials. High hardness (86-93HRA, equivalent to 69-81HRC); good thermal hardness (up to 900-1000 DEG C, 60HRC); good wear resistance.Carbide cutting tools than high speed steel cutting speed 4-7 times, 5-80 times higher tool life. Manufacturing dies and measuring tools, life expectancy is 20-150 times higher than alloy tool steel. Hard material that can be cut around 50HRC. But the hard alloy brittleness, cutting can not difficult to make the whole cutter with complicated shape, usually made of different shapes of blade, mounted on the body or use a knife die body by welding, bonding and mechanical clamping method.
