Products Description
Centrifugally cast compound steel back -up rolls have a shell of cast steel with alloying elements such as Ni,Cr,Mo.After heat-treatment the roll shell get a fine temper structure, which exhibits good strength and ductility combined with high fatigue properties. When used, the roll shows a high wear and spalling resistance all the time.

- Q: What type of carbide for punching dies? Better. Where can I buy it?
- Stamping die is divided into cold stamping and hot stamping, need more different uses to choose different characteristics of carbide brand, you can understandZhuzhou same cemented carbide.
- Q: Compare the advantages and disadvantages of high speed steel and cemented carbide
- High speed steel, high carbon steel, can be divided according to chemical composition of tungsten and molybdenum in steel, cutting performance is divided into high performance of ordinary high speed steel, high speed steel. Through strengthening heat treatment of high speed steel.
- Q: What kind of cemented carbide is the most wearable?
- Carbide wear is due to the grain size and the cobalt content determines the finer granularity of cobalt content is lower, the higher hardness and lower hardness should be mentioned is the selection of wear-resistant hard alloy not only the hardness to see the use of general cutting hard alloy material with YW2 a relatively high hardness but if the working conditions impact operations more frequently if it should take into account its toughness but the toughness and hardness is conflicting under such circumstances can choose the class YG fine grain alloy
- Q: What are the parameters of the wear resistance of cemented carbides in addition to their hardness?
- Even the best knives in the world, if not1, reasonable processing parameters;2 、 proper installation and use;3 、 timely maintenanceAnd so on, it will turn into a scrap of iron in a short time.
- Q: What cemented carbide does 2gr13 use?
- 2Cr13 martensitic stainless steel can be processed by hard alloy YW2, carbide YW2 suitable for heat-resistant steel, high manganese steel, stainless steel and advanced alloy steel and other special difficult to processing steel finishing, semi finishing.
- Q: What kind of grinding wheel is the most suitable for carbide tools?. My existing grinder, 2800 rpm, /s wheel diameter, can hold 250mm. Please help answer.
- Commonly used in 200*25*32 or 250*25*32 green carbide grinding wheel, hardness K or L, particle size 60.Cemented carbide: an alloy material made from powder metallurgy by hard metals and bonded metals of refractory metals. 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. Now, the cutting speed of new carbide tools is several times that of carbon steel. 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.
- Q: Fuzhou where to buy steel tungsten carbide
- How will you buy the blade right I can express to you
- Q: I would like to ask, carbide processing, cutting what cutting fluid is better, useful trouble recommended, thank you!
- An alloy material made from powder metallurgy by hard metals and bonded metals of refractory metals. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance.
- Q: What materials are hard alloys used to process?
- YW hard alloy, high temperature resistant, wear-resistant, high hardness steel, stainless steel and so on.
- Q: YW2 carbide blade type
- YW2 general cylindrical turning tool head type: A325 20pcsCemented 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.
