Product Introduction

Stellite Valve Stem is a critical component used in valves, usually made of Stellite alloy. Stellite is a cobalt-based alloy that offers extremely high resistance to wear, corrosion and high temperatures, making it excellent in demanding working environments.

Main features and benefits

Stellite04
High wear resistance: Stellite alloy contains a large amount of hard phases (such as carbides), which gives it excellent wear resistance in high-wear environments.

Corrosion Resistance: This alloy is resistant to corrosion from a variety of chemicals, including acids, alkalis, and salt solutions.

High temperature resistance: Stellite alloy maintains its mechanical strength and hardness in high temperature environments and is not easily deformed or degraded.

Low coefficient of friction: In friction applications, Stellite alloys exhibit a low coefficient of friction, helping to reduce wear and increase service life.
Application areas

Oil and Gas Industry: Due to its excellent wear and corrosion resistance, Stellite valve stems are widely used in oil and gas drilling equipment.

Chemical Industry: In equipment handling corrosive chemicals, Stellite valve stems ensure long life and reliable operation of the equipment.

Power plants: Valves operating under high temperatures and pressures require the use of high-performance materials, and Stellite stems are ideal.
Aerospace: Some high-performance engines and other high-temperature components also use Stellite alloys.
