Stellite 1 Alloy

SYTOP, a leader in cobalt alloy manufacturing, delves into the unique properties of Stellite 1 alloy. This cobalt-based alloy is distinguished by its complex carbides, offering unparalleled wear and corrosion resistance, even under extreme temperatures.

Composition and Characteristics

Stellite 1 alloy is composed of an alloy matrix featuring complex carbides, primarily of cobalt, chromium, tungsten, and carbon. This composition results in a material that is not only hard and wear-resistant but also maintains its integrity in high-temperature environments, exceeding 760°C (1400°F).

Exceptional Wear Resistance

The alloy's wear resistance is primarily due to the hard carbide phase dispersed in a CoCr alloy matrix. Stellite 1 contains a high proportion of these hard, wear-resistant primary carbides, making it ideal for situations involving extreme low-angle erosion and severe abrasion.

Specific Applications

Stellite 1 is particularly effective in applications such as pump sleeves, rotary seal rings, wear pads, expeller screws, and bearing sleeves. Its abrasion and corrosion resistance make it a preferred choice for components that require prolonged durability and reliability.

Handling and Machining

While Stellite 1 offers superior hardness and wear resistance, it is more crack-sensitive compared to other Stellite alloys. Care is taken during casting and hardfacing processes to minimize cooling stresses. Due to its high hardness, Stellite 1 is typically finished by grinding.
