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.

Q:One can write on the hard alloy on the pencil, what's the name ah, who knows.
You need it. It's all there. You're over there
Q:What material is that ultrafine cemented carbide?
The main component of cemented carbide is tungsten carbide, so also known as tungsten steel, tungsten steel belongs to hard alloy, also called tungsten titanium alloy. The hardness can reach HRB89 to 95Tungsten steel production process is as follows: the powder is pressed into a blank, and then into the furnace heated to a certain temperature (sintering temperature), and keep a certain time (time), and then cooled down to obtain the required properties of tungsten materials.The characteristics of ultrafine cemented carbide is the main component of WC, compared to the hard phase and general hard alloy, the hard phase particles are very fine (average grain size less than 1um), so you can get a higher than the general hard alloy of the same hardness strength (toughness), edge grinding can be sharper and better wear resistance.
Q:What about cemented carbide produced in Zhuzhou? What brand is good?
Is good at home, as for the brand well of course is diamond, refined into a brand is also good, there are fine into hard alloy sales company, previously entered a large red facade, product is very much, the Diamond Road No. 24-5, hope to help to you.
Q:What kinds of carbide knives do you have? Write out its main functions and uses.
The commonly used cemented carbides are mainly based on WC, and are classified into the following categories whether or not they are added to other carbides:(1) tungsten cobalt (WC+Co) cemented carbide (YG);It consists of WC and Co, has high flexural strength toughness, good thermal conductivity, but poor heat resistance and wear resistance, mainly for the processing of cast iron and non-ferrous metals. YG hard alloy fine grain (such as YG3X, YG6X), in the same amount of cobalt, its hardness wear resistance than YG3, YG6 high strength and toughness is poor, suitable for machining hard cast iron, austenitic stainless steel, heat-resistant alloy, hard bronze.
Q:Machining center 8 mm carbide cutter processing 45 steel, how to set the speed, feed, and moving speed?
if the speed in the three thousand, each Z axis 0.3 wire feed, can be a little faster, must spiral knife Oh, this is not a knife eat 5 mm. I found a 55 degree flat cutting parameters of tungsten steel milling table
Q:Can ceramic tools process cemented carbides?
No, ceramic cutters are usually used to process cast iron (high speed machining) and high hardness steel (Cui Huogang).Generally, the hardness of ceramic tools reaches HRA91-95, while the hard alloy can reach HRA93.The main components of ceramic tool materials are Al2O3 with high hardness and melting point. Si3N4 and other oxides and nitrides, and then added a small amount of metal carbide, oxide or pure metal additives, formed by pressing, sintering, and then a tool material. Its hardness can reach HRA91 ~ 95, and the hardness of HRA80 can still be kept at the cutting temperature of 1200 DEG C. In addition, the chemical inertia is large, the friction coefficient is small, and the wear resistance is good, and the service life of the processed steel pieces is 10~12 times of that of the hard alloy.Its major disadvantages are brittleness, low bending strength and low impact toughness. Therefore, it is mainly used for semi finishing and finishing, high hardness, high strength steel and chilled cast iron and other materials. Commonly used ceramic cutting tools are alumina ceramics, composite alumina ceramics and composite silica ceramics.Taiwan is hard gold metal carbide with high heat resistance and high wear resistance (WC tungsten carbide, titanium carbide, tantalum niobium carbide TiC TaC, NbC etc.) and metal binder (cobalt, nickel and molybdenum) powder metallurgy products under high temperature sintering. The hardness of HRA8 9 ~ 93, 850 ~ 1000 DEG C high temperature resistant, has good abrasion resistance, allowing the use of the cutting speed can reach 100 ~ 300m / min, can be a variety of materials including machining hardened steel, therefore it is widely available.
Q:Can hard alloy be used in food?
Used for processing food should not be possible, the composition of tungsten carbide.
Q:How are carbide cutters made? 20
CNC carbide cutter is used to hard alloy powder and powder metallurgy mould after sintering, the hard alloy blade (blank, can not be directly used), then after grinding the surface and edge (this can be installed on the cutter head, and also can be used) in coating the surface to improve its wear resistance, have finished milling blade.The blade is machined with a special blade grinder.
Q:Where can I use cemented carbide?
Modern ultra hard alloys are produced by sintering of carbides of tungsten carbide and some other elements. It is the hard metal (tungsten, tantalum, titanium, molybdenum, etc.) carbide carbide particles, with one or several iron elements (cobalt, nickel or iron) powder mixed, pressed molding, and then made by sintering.Cemented carbide is the most powerful alloy in the world at present. Hard alloy widely used now has two main categories: the first is to do the cobalt WC alloy binder; the second is to make titanium carbide alloy tool steel binder.Cemented carbide is used as a tool, and its hardness will not decrease even at high temperatures of 1000 degrees. Therefore, for high speed cutting, cutting speed up to 2000 meters per minute, 100 times higher than the ordinary carbon steel cutter, tungsten steel cutter is 15 times higher than. The mold made of it can be punched about 3000000 times, which is 60 times longer than the ordinary alloy steel die.
Q:What are the well-known brands of cemented carbide materials at home and abroad?
Foreign - Sweden Sandvik, Germany - Luxemburg, American Kenna, Israel - Domestic - hard line iscar; diamond, Zigong the Great Wall, Xiamen gol-egret etc..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.
