About Stellite 25 Product

Stellite 25 Alloy

Nominal Composition (Mass %) and Physical Properties

Stellite 25 is a tungsten-reinforced cobalt-chromium alloy that is a cast version of the forged alloy L605 and is also available in hard-faced wire, rod, and powder. This special low-carbon alloy was found to have excellent resistance to thermal fatigue and could be used in tools for machining hot steel. The alloy also resists hot metal-on-metal wear.

 Stellite 25 is typically used in metalworking tools such as piercing points, forming tools, extrusion dies and furnace hardware where a combination of metal-to-metal wear, thermal fatigue and hot corrosion resistance is required.

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.
