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. Stellite 6 is used on valve seats and gates; pump shafts and bearings, erosion shields and rolling couples. It is often used self-mated.

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 for forging dies, Stellite 250 and 251 are used exclusively for various parts in the furnace.

2.Stellite Alloy 6 , 306, 506

These alloys have moderate carbon content (0.5%~1.6%) and are less ductile than stellite 7, 8 and 31. They are generally 1% at room temperature and have a slightly higher hardness (HRC 43), but they have good wear resistance and high temperature resistance. These alloys are used as castings and also have thermal shock resistance. Therefore, they can not only be used as sealing surfaces for steam valves and chemical valves but also parts for contact with hot steel and hot scissors. Stellite 306 is a cobalt-based tube wire commonly used to repair hard-faced coatings on parts subject to thermal shock and mechanical shock. Stellite 506 is also a cobalt-based tube filament with the same hardness as the stellite 6.

Cobalt Alloy Has Excellent Wear Resistance

Cobalt Alloy Has Excellent Wear Resistance. The cobalt alloys today are little changed from the early alloys of Elwood Haynes. The most important differences relate to the control of carbon and silicon (which were imparities in the early alloys). Carbon content influences hardness, ductility, and resistance to abrasive wear.

There are several distinct types of wear which generally fall into two main categories:

l Abrasive wear

l Sliding wear

The type of wear encountered in a particular application is an important factor that influences the selection of a wear-resistant material.

Abrasive wear is encountered when hard particles or hard projections (on a counter-face) are forced against and moved relative to a surface. The terms high and low stress abrasion relate to the condition of the abrasive medium (be hard particles or projections) after interaction with the surface. If the abrasive medium is crushed, then the high stress condition is said to prevail. If the abrasive medium remains intact, the process is described as low stress abrasion. Typically, high stress abrasion results from the entrapment of hard particles between metallic surfaces (in relative motion), while low-stress abrasion is encountered when moving surfaces come into contact with packed abrasives, such as soil and sand.

In alloys such as the cobalt-base wear alloys, which contain a hard phase, the abrasion resistance generally increases as the volume fraction of the hard phase increases. Abrasion resistance is, however, strongly influenced by the size and shape of the hard phase precipitates within the microstructure and the size and shape of the abrading species.

Sliding Wear. Of the two major types of wear, sliding is perhaps more complex, not in concept, but in the way different materials respond to sliding conditions. Sliding wear is a possibility whenever two surfaces are forced together and moved relative to one another. The chances of damage are increased markedly if the two surfaces are metallic in nature, and if there is little or no lubrication present.
