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:How to distinguish cemented carbide grades?
- (3) titanium cobalt tungsten tantalum carbide (WC+TiC+TaC+Co)) (YW YS) "the main processing of heat resistant steel, high manganese steel, stainless steel and other hard materials processing" in addition to TaC YT hard alloy on (NbC), improve the bending strength, impact toughness, high hardness, wear-resistant and anti oxygen ability. Can be processed and can be made of steel, cast iron and non-ferrous metals. It is often called the universal hard alloy (also known as the universal hard alloy). The following is a variety of grades, density, bending strength, hardness and flexural strength hardness grade use density of use of YG3X 14.6-15.2 132092 is suitable for cast iron, nonferrous metals and alloy steel small alloy steel cutting section of high-speed machining. K01 YG3X YG6A 14.6-15.0 137091.5 for hard cast iron, non-ferrous metalsalloys, also suitable for high manganese steel, hardened steel, alloy steel and semi finishing K05 YG6A YG6X 14.6-15.0 finishing. 142091 it is proved that the alloy processing of chilled alloy cast iron and alloy steel can obtain good results, finishing is suitable for ordinary iron. K10 YG6X YK15 14.2-14.6 210091 for the whole processing of drilling, milling, reaming and alloy cutter. Have high wear resistance and toughness of K15. K20 YK15 YG6 14.5-14.9 138089 is suitable for cast iron, nonferrous metals and alloy non metallic materials at medium cutting speed precision. K20 YG6 YG6X-1 14.6-15.0 150090 is suitable for cast iron, nonferrous metals and alloy non metal material during continuous cutting finishing, discontinuous cutting the semi refined car, fine car, small car, coarse fine car section thread, continuous section semi finishing milling and finish milling, rough and fine hole expansion. K20 YG6X-1 YG8N 14.5-14.8 200090 is suitable for cast iron, cast iron, ductile iron and chromium, High speed machining of nickel stainless steel alloy.
- 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:Processing stainless steel 301 milling thickness of about 3 millimeters, with what blade good?
- Friends, according to your question, if change my words, I choose YS25Grade ISO grouping, code name, density, bending strength, hardness, useYS25 12.8 P25 13.2 = 1780 = 90.5 for carbon steel, cast steel, high manganese steel, high strengthRough turning, milling and planing of steel and alloy steelYou mainly milling the surface is not refined, there is no need to use that good, in one is YS25, cheap, well, that's it, if there is any good advice to my replies
- Q:What does WC refer to in cemented carbides?
- Tungsten, titanium and cobalt carbideThe main components are tungsten carbide, titanium carbide (TiC) and cobalt.The grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide.For example, YT15, which represents average TiC=15%, is tungsten carbide cobalt carbide with the remainder of tungsten carbide and cobalt content.Tungsten, titanium, tantalum (niobium) carbidesIs the main component of tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. This kind of hard alloy is also called universal cemented carbide or universal hard alloy.
- Q:It is hard alloy steel
- Tungsten steel and hard alloy: tungsten carbide is the difference is a. Tungsten is raw material for smelting ferrotungsten adding steelmaking process in molten steel for tungsten and also called high speed steel or tool steel, the tungsten content in 15-25%; and the hard alloy is used in powder metallurgy process of tungsten carbide and cobalt as the main body or other binding metal sintering, the tungsten content in general in more than 80%. Simply put, all the hardness go more than HRC65 things, as long as the alloy can be called carbide.
- Q:What is the base material of carbide saw blade?
- You can go to Zhuzhou tungsten alloy technology forum to see, detailed description of the carbide saw blade related knowledge, you can go to a lot of professionals with whom to communicate inside.
- Q:What materials are hard alloys used to process?
- YG hard alloy, impact resistance, high temperature resistant, processing pig iron.
- Q:I would like to ask, carbide processing, cutting what cutting fluid is better, useful trouble recommended, thank you!
- Therefore, the processing of cemented carbide selection of the correct cutting fluid can produce good results, the general cutting fluid is not good, the quality of processing is very poor.
- Q:Which prawns know of what is called red hard alloy.
- A large amount of microscopic motion of microscopic particles (molecules, atoms, etc), i.e., irregular motion of a large number of microscopic particles that make up macroscopic objects or systems.
- 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.
