Stellite Rod Using in Machinery Industry Widely

 

As is known to us, widely used in the machinery Industry, Stellite Alloy rod is 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.

Stellites of this rod of are Stellite Alloy 3 available in two main combinations: (a) a Tungsten(W) group with the composition of Co-Cr-W-C, and (b) a Molybdenum (Mo) group containing Co-Cr-Mo-C. Stellites possess outstanding corrosion resistance, oxidation resistance, wear resistance, heat resistance, and low magnetic permeability. Components made of stellites work well in highly corrosive environments and maintain these advantageous properties at elevated temperatures. Components made of stellites are widely used in oil and gas, automotive, nuclear power, paper and pulp, chemical and petrochemical, refineries, automobile, aerospace and aircraft industries.

By virtue of their nonmagnetic, anti-corrosive and non-reactivity to human body-fluid properties, stellites are used in medical surgery and in surgical tools, tooth and bone implants and replacements, heart valves, and in heart pacemakers. The hardness range of sellites is from 32 to 55 HRC, which makes stellites brittle materials but they have a low Young’s modulus.

Due to their high hardness, dense but non-homogeneous molecular structure and lower thermal conductivity, machining operations for parts made of stellites are extremely difficult, categorizing stellites as difficult-to-machine materials like Ti-alloys, inconels, composites and stainless steel. Usually, machine components made of stellites are produced by a deposited stellite are then finished by grinding, rather than some other economic machining process, which is costly and time-consuming, making stellite products very expensive.

Stellite Alloys Are A Group Of Cobalt-chromium ‘Super-Alloys’

 

Stellite Alloy are a range of cobalt-chromium alloys composed by complex carbides in an alloy matrix. They have high wear resistance, superior chemical and corrosion performance under harsh environment. Stellite is a trademarked name of Kennametal Inc. Prior to that, it was owned by Union Carbide, Stellite Division. Invented by Elwood Haynes in the early 1900s as a substitute for cutlery that stained (or that had to be constantly cleaned). Next, let me introduce about Stellite alloy to you.

Chemical Properties

There is a variety of types of stellite. All types contain the following elements in different quantities: titanium, Silicon, Sulfur, Phosphorus, Molybdenum, Manganese, Chromium, Carbon, Boron, Aluminum, Iron, Nickel, Cobalt

Most of these alloys contain four to six of those elements. Among all those elements, carbon and chromium are of greatest importance, playing the biggest roles in how the alloy performs.

Manufacturing Process

Stellite alloys are produced by a range of different processes or methods. These methods include wrought or hot forging, hard-faced deposit, powder metal, and finally, casting. It’s more difficult to machine and grind than steel. Therefore, high-performance processing equipment and specialized machining tools are required. As usual, it is machined by grinding instead of cutting.

Applications

Some of the major applications are as follows:

l Poppet valves, valve seats and exhaust valves of the internal combustion engine.

l Medical applications including manufacturing of artificial hip joints, other bone replacements and cast structure of dental prosthesis.

l Saw teeth, hardfacing, and acid-resistant machine parts.

l The manufacture of turning tools for lathes. With the introduction and improvements in tipped tools it is not used as often, but it was found to have superior cutting properties.
