About Stellite 19 Product Italia

Stellite 19 Alloy

Nominal Composition (Mass %) and Physical Properties

Stellite cobalt-based alloys consist of complex carbides in the alloy matrix. They are resistant to abrasion, abrasion and corrosion and retain these properties at high temperatures. Its excellent wear resistance is mainly attributed to the unique inherent properties of the hard carbide phase dispersed in the CoCr alloy matrix.

One of the standout properties of Stellite 19 is its ability to stay strong under red heat. This represents a temperature range of 932 to 1562°F. Stellite 19's impact resistance is comparable to high-speed steel, but its red hardness is higher. Stellite 19 can be used at higher speeds than HSS. The alloy's excellent resistance to corrosion by many common chemicals and its wear-resistant properties allow it to be used economically when processing materials such as plastics and rubber, freeing up the corrosive agents used in the manufacturing process.

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.
