Stellite Alloy 12 Sytop

Stellite Alloy 12 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 12 Saw tips are made of Stellite alloy in grade Co12,so the following information is all about Co12.
(1). Stellite Alloy 12 could be considered an intermediate alloy .
(2). It contains a higher fraction of hard, brittle carbides than Stellite Alloy 6
(3).It has increased resistance to low angle erosion, abrasion, and severe sliding wear while stretaining reasonable impact and cavitation resistance.
(4). Stellite Alloy 12 is often used self-mated or running against.

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...

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...
