The Efficacy of Carbon Component on WC-tic-co-cemented Carbide

WC Co cemented carbides are easy to oxidize and decompose in high temperature application, which have many problems, such as brittleness, brittle fracture, processing softening and edge breaking, etc. they are still not suitable for high speed cutting of steel, so they have great limitations. WC tic co cemented carbides are known to have wear resistance, oxidation resistance and crater wear resistance. However, due to the fact that tic and its solid solution are much more brittle than WC, this alloy also has relatively large defects, that is, the toughness and weldability of the alloy are poor. Moreover, when the … Read more

New Breakthrough of Tungsten Carbide with Superior Properties of the Beijing University

Due to its high hardness and wear resistance, tungsten carbide  is widely used as a variety of processing tool materials, known as “industrial teeth”. Among them, WC Co tungsten carbide  is the largest production and consumption of tungsten carbide  materials. After decades of development, in the engineering application of tungsten carbide , the hardness and wear resistance can basically meet the requirements of service performance, while the fracture strength and impact toughness are the bottleneck of expanding the application of tungsten carbide , especially the high-end application. For a long time, there is a lack of systematic understanding about the … Read more

Through the transfer of materials, the total volume shrinks, the density increases, and finally it becomes a dense polycrystalline sintering body with a certain microstructure. principle of sintering furnace Sintering principle of cemented carbide: the bonding phase, … Read more

Key Points for Stainless Steel Processing

In our daily life, no matter in small tableware or decoration, stainless steel processing is more and more widely used. So what should we pay attention to in the key points of stainless steel processing? Next, let’s have a brief introduction for you. There are many reasons why stainless steel processing is important in the application field of building stainless steel processing. Corrosion environment requires smooth surface because it is not easy to scale. The deposition of dirt can rust or even cause corrosion of stainless steel. In the spacious hall, stainless steel is the most commonly used material for … Read more

Do You Have the Basic Knowledge of Cemented Carbide Materials?

Cemented carbide is the most widely used high speed machining (HSM) tool material. This kind of material is produced by powder metallurgy process, which is composed of cemented carbide (usually tungsten carbide WC) particles and soft metal bond. At present, there are hundreds of different components of WC based cemented carbides, most of them use Cobalt (CO) as binder, nickel (Ni) and chromium (CR) are also commonly used binding elements, in addition, some other alloy elements can be added. Grades of simple cemented carbide These grades used in metal cutting usually contain 3% – 12% cobalt (weight ratio). The size … Read more

What is low alloy structural steel

Low alloy structural steel refers to the alloy structural steel with total alloy composition less than 5%. The carbon content of this kind of steel is similar to that of low carbon steel, and it is mainly strengthened by a small amount of alloy elements to improve toughness and weldability. Its strength is much higher than that of the same carbon steel. Widely used in pressure vessels, chemical equipment, boilers, bridges, vehicles, ships and large steel structures. Alloy elements such as manganese, silicon and molybdenum cause solution strengthening. Vanadium and niobium can refine grains and improve toughness. Molybdenum can improve … Read more
