Stellite turbine impellers have outstanding performance characteristics. They are usually made of Stellite alloy, which has excellent high-temperature strength, wear resistance and corrosion resistance.
Structurally, Stellite turbine impellers are carefully designed to optimize fluid dynamics and improve working efficiency. Its blade shape and distribution can effectively convert the energy of the fluid into mechanical energy.
Due to the characteristics of Stellite alloy, Stellite turbine impellers can maintain stable performance in high temperature, high pressure and harsh working environments, reduce wear and corrosion, and thus extend service life.
Stellite alloy has extremely high hardness and wear resistance due to the cobalt and other hard alloy elements (such as chromium, molybdenum, tungsten, etc.) it contains. This allows the manufactured turbine impeller to operate for a long time without damage in high-speed rotation and high-friction environments, greatly extending the service life of the equipment.
Stellite alloy still maintains stable mechanical properties and structural integrity at high temperatures. This allows Stellite turbine impellers to withstand working conditions in high-temperature environments, such as applications in aircraft engines and gas turbines, and provide reliable power output.
The corrosion-resistant elements such as chromium make Stellite alloy have excellent corrosion resistance and can resist the erosion of chemical media. This makes Stellite turbine impellers suitable for a variety of corrosive environments, such as applications in the chemical industry and marine engineering.
Stellite alloy has excellent strength and rigidity, and can maintain stable performance under high-speed rotation and high pressure. This property enables turbine impellers to withstand the challenges of fluid dynamics and mechanical loads without deformation or damage.
Investment casting: suitable for manufacturing impellers with complex shapes and internal channels. The precision and surface quality of the impeller are ensured through precise casting processes.
Machining: including processes such as milling, turning and grinding to ensure that the impeller meets the designed geometric requirements and surface roughness.
Heat treatment: Through heat treatment processes such as solid solution treatment and precipitation hardening, the grain structure of the alloy is adjusted and the hardness is increased to enhance the mechanical properties of the impeller.
Aerospace: used for impeller components in jet engines and turbochargers, which can provide reliable power output under high speed and high temperature environment.
Energy industry: especially gas turbines and turbochargers, used to provide efficient energy conversion and power output.
Chemical industry: used to manufacture impellers for pumps, valves and other liquid handling equipment to resist corrosive media and provide long-lasting wear resistance.
