Phosphorus iron honeycomb appearance, phosphorus is 20-26%, 0.1 6% of intergrowth compounds containing silicon. Phosphorus in the steel industry as an alloying agent, iron alloy additives for use in the metallurgical and deoxidizer.

In general steel products, phosphorus is harmful ingredients, but in some special products, the addition of phosphorus, can improve the performance of certain aspects of steel. Phosphorus iron is widely used in roll, auto cylinder liner, engine roller and large castings in order to increase mechanical parts corrosion resistance and abrasion resistance

Q: Tungsten carbide cutter white steel cutter carbide cutter is what is the difference?: Xing bautec supply Foxconn tungsten steel milling cutter, should also be rightWhite steel milling cutter used for low speed turning, workpiece roughness is better than carbide blade! Hard alloy is harder than high speed steel, but hard alloy is more brittle than white steel and easy to break.Hard alloy milling cutters are mainly composed of rare metals.

Q: Carbide blade domestic that tricky point?: China's carbide cutting tools must be the best cemented carbide in Zhuzhou.

Q: What kind of material is the alloy drill bit?: the hardness is relatively high, generally above HRC90 degrees, and it is suitable for batch processing and hard processing!

Q: Carbide according to the structure of the words, what can be divided into?: Hard alloy is by grade, can be made into all kinds of special-shaped parts

Q: Carbide grades, properties and applicable ranges: (2) tungsten titanium cobalt (WC+TiC+Co) cemented carbide (YT);Because of the hardness and melting point of TiC was higher than WC, so compared with YG, the hardness, wear resistance, hardness increases, bond high temperature, strong antioxidant capacity, and will generate TiO 2 at high temperature can reduce the adhesion. But poor thermal conductivity, low flexural strength, so it is suitable for processing steel etc. the toughness of materials.

Q: How much does carbide WC contain?: For example, YG8, tungsten carbide cobalt alloy that represents an average WCo=8% and the rest of tungsten carbideTungsten, titanium and cobalt carbideThe main components are tungsten carbide, titanium carbide (TiC) and cobaltThe grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide.

Q: What kinds of carbides are there? How should we choose in production?: Tungsten cobalt carbide (YG): suitable for brittle materials such as cast iron;Tungsten cobalt titanium carbide (YT): it is suitable for processing plastic materials, such as steel;General purpose cemented carbide (YW): commonly used for processing stainless steel, heat-resistant steel, high manganese steel and other difficult to process materials.

Q: Is nickel base alloy hard alloy?: 2, YT--- tungsten cobalt titanium alloy products, applicable to coarse, carbon steel and alloy steel uneven section in interrupted cutting when the YT5 rough planing, semi finishing, discontinuous surface rough milling and drilling.

Q: The welding welding hard alloy cutter, should use what type of flame why: With the fire on it. Put the knife and put some red hot and then put up with borax alloy outer flame burning red and then placed in a good point copper alloy and borax on the use of knife gap flow with upper and lower outer flame burnt gap can be

Q: Printing requirements for cemented carbide: Its disadvantages are: there are a small amount of pores and defects in the product, and the carbon content of the sinter will decrease.Hot isostatic pressing sintering in sintering with inert gas, liquid metal or solid particles as pressure transfer medium in each direction of the sintered body exert equal pressure, not even this can overcome ordinary hot pressing pressure is not uniform and the resulting product performance. The hot isostatic pressing of cemented carbide can eliminate the pores in the alloy and the drilling pool after sintering, and restrain the growth of WC grain. The Kennametal Inc installed the first heating chamber for 277mm * 1270mm in 1967. The temperature is up to 1500oC and the pressure can reach140MPa's hot isostatic pressing machine has taken the lead in successfully applying the technology of hot isostatic pressing to the production of cemented carbide. Since then, hot isostatic pressing technology has developed rapidly in foreign countries (especially in the United States).
