Stellite Alloy 6 (Stellite 6) Biref Information

The professional Stellite Alloy manufacturer - Shenyang Top New Material Co.,Ltd, since its inception in 2001, and after many years of development and growth, the company is now playing a leading role in stellite alloy manufacture industry in China. Stellite Alloy 6 is the most widely used cobalt base alloy and exhibits good all-round performance. It has excellent resistance to many forms of mechanical and chemical degradation over a wide temperature range, and retains a reasonable level of hardness. Particular attributes are its outstanding self-mated anti-galling properties (which result in its wide use as a valve seat material), its high temperature hardness, and a high resistance to impact and cavitation erosion. The alloy is ideally suited to a variety of hardfacing processes. It has less tendency to crack than Stellite 12 in multiple layers, but is more wear resistant in abrasion and metal-to-metal or galling conditions. It can be turned with carbide tooling.

Various Grades of Stellite Alloy

As a special engineering material, Stellite Alloy has been widely used. It has excellent performance in high temperature resistance, wear resistance, cavitation resistance and corrosion resistance, but the performance of alloys of different grades is also very different. Some grades of alloys are designed for a specific purpose. When used, the grades must be carefully selected to achieve superior performance. The main properties and uses of various types of stellite alloys are summarized as follows: 1. Stellite 7, 8, 21, 37, 208, 250 and 251 Reinforced with elements such as molybdenum, nickel and niobium, these seven alloys are all low carbon alloys. Although their room temperature hardness is low, it will be improved after cooling, and it has extremely high temperature corrosion resistance, thermal shock resistance, high temperature strength and best ductility. Commonly used in gas turbine blades, brass molds and extrusion dies, Stellite 208 is specifically designed f

Stellite Alloy Valve Seat (Advantages and Features)

Shenyang Top New Material Co.,Ltd is a professional Stellite Alloy and cobalt chrome alloy manufacturer, due to good fame and sales channel, perfect products and services, we served satisfied customers in over 50 countries. Advantages of Sytop Stelltie Alloy Valve Seat With uniform and Compace Structure No shrink, porosity ect defects with better properties stable quality from batch to batch What`s the Feasures of Sytop Stellite Alloy 6 ? 1. High temperature resistance The strength keeps stable up to 800℃ and it can even momentarily used at 1200℃. 2. Wear resistance Due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a CoCr alloy matrix, it has exceptional wear and galling resistance. 3. Corrosion resistance This exellent and lovely property allows this kind of material parts to be used in oil&gas, slurry, acid liquid and any other mediums. During the past developed, we have got the support and care from cust

Stellite Alloy Blade Is Widely Used in Textile Industry

As a matter of fact, the Viscose Staple Rayon Fiber Cutter Stellite Alloy Blade is one of the cobalt alloys. With special chemical composition, it is widely used in textile industry. We control the core technology to produce this kind of cutter blade through powder metallurgy. Corrosion resistance and wear resistance of this blade are better than other material. We have various specifications of stellite alloy blade which can be provided for customers according to their requirements. It is known to us that stellite alloy blades are produced by a range of different processes, including wrought or hot forging, hard-faced deposit, powder metal, and finally, casting. It’s more difficult to machine and grind than a steel blade. Therefore, high-performance processing equipment and specialized machining tools are required. As usual, it is machined by grinding instead of cutting. Sytop Stellite Alloy 3 applies to the production line which produces viscose staple fiber and w

Stellite Alloy 12 (Stellite 12)

Stellite Alloy consist of complex carbides in an alloy matrix. Their exceptional wear resistance is due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a CoCr alloy matrix. Stellite Alloy 12 Saw tips are made of Stellite alloy in grade Co12,so the following information is all about Co12. Stellite 12 can be considered as an intermediate alloy between Stellite 6 and Stellite 1. It contains a higher proportion of hard brittle carbides than Stellite6 and has enhanced resistance to low angle erosion, wear and severe sliding wear while maintaining reasonable impact and cavitation resistance. Stellite 12 is typically used to self-fit or run Stellite 6 or Stellite 1. Higher tungsten content provides better high temperature performance than Stellite 6, and can be used at temperatures up to about 700˚C. Stellite 12 is typically used in cutting tools that need to withstand wear, heat and corrosion. Examples include industrial knives for cu

The Difference Between Cobalt Alloy And Nickel Alloy

The Difference Between Cobalt Alloy And Nickel Alloy. 1.Thermal stability One of the important reasons why cobalt alloys are used as aviation material is its excellent thermal stability. Cobalt alloys have a high melting point and thermal conductivity and less thermal expansion after heating. It can be seen from this that cobalt alloys have advantages in thermal stability. Compared with cobalt alloys, nickel alloys have a higher strength but more brittle. It is easier to be broken on occasions of impact. When the temperature rises to 800℃ (the operating temperature of some engines), nickel alloys can’t be used, while cobalt alloys retain strong. 2.Stiffness The stiffness means the ability to resist deformation. Nickel alloys have a lower stiffness than cobalt alloys in various temperature. With the temperatures above 700℃, the properties of nickel alloys are completely destroyed. 3.Oxidation resistance Cobalt Chromium Alloy has superior resistance to high-tem
