About Stellite 700 Alloys Product

Stellite 700 alloy is a cobalt-based alloy with chromium and molybdenum as the primary alloying elements. The unique combination of wear and corrosion properties results from the high volume fraction of carbide particles and the high degree of solid solution strengthening brought about by the addition of molybdenum. STELLITE 700 alloy has been particularly successful in petrochemical and refinery applications such as delayed coker heater return lines, catalyst recovery lines and transfers, and FCC feed and regenerator air and grid nozzles. It is also a good choice for valve seats, slides and general flow control applications where corrosion and wear are key considerations. 700 Series alloys have a wide range of applications where high levels of wear and corrosion are present.

Stellite 700 Alloy

Stellite 700 alloy raises the bar for wear- and corrosion-resistant alloys. They offer a unique combination of outstanding wear resistance and superior corrosion resistance in reducing or complex environments.

Stellite 720 coating uses a proprietary UltraFlex™ process to apply this extremely wear- and corrosion-resistant alloy to the surfaces of complex and non-line-of-sight components. Stellite 720 can also be used as an additive manufacturing component.

Stellite 700 alloy is based on the traditional Stellite grades 6, 12, 3 and 20, but the tungsten has been replaced by molybdenum. This allows them to maintain hardness and wear resistance while significantly improving corrosion resistance in reducing environments. 700 series alloys are more brittle than equivalent conventional Stellite alloys.

Available product forms:

Stellite 700 series alloys are available as powder metallurgy components, welding rods, wires and powders.

Stellite 706, 712 and 703 are available as castings.

Stellite 720 is available as an UltraFlex coating and additive manufacturing component.

According to drawings or samples

Stellite alloys are a group of cobalt-chromium alloys known for their exceptional wear resistance, high temperature performance and corrosion resistance. Here's an overview of Stellite:

Composition:

Stellite alloys are primarily composed of cobalt (about 50-65%) and chromium (about 25-30%), with varying proportions of tungsten, carbon and other elements depending on the grade. These alloying elements give Stellite alloys a unique combination of properties.

Wear Resistance:

Stellite alloys are known for their excellent wear resistance, making them suitable for applications where components are subject to abrasive wear, erosion and sliding contact. They are typically used in high-wear environments such as cutting tools, saw teeth, valve seats, and pump components.

High Temperature Performance:

Stellite retains its mechanical properties at high temperatures, allowing it to withstand high temperatures without significant loss of strength or hardness. This makes Stellite alloys suitable for high-temperature applications such as gas turbine components, furnace components and exhaust valves.

Corrosion Resistance:

Stellite alloys exhibit good corrosion resistance in a variety of environments, including acidic and alkaline solutions, as well as high-temperature gases and molten salts. This corrosion resistance makes Stellite alloys suitable for use in chemical processing, marine engineering, and oil and gas production.

Versatility:

Stellite alloys are available in a variety of grades and forms, including powders for thermal spray coatings, castings and forgings such as rods and plates. This versatility allows the selection of the most appropriate grade and form of Stellite alloy for a specific application.

Applications:

Stellite alloys are widely used in aerospace, automotive, oil and gas, power generation and manufacturing industries. They are widely used in components requiring wear resistance, high temperature performance and corrosion resistance.
