High Heat Resistance Silicon Nitride Ceramic Positioning Pin with SS304 Base
1 . Material Introduction:
Silicon Nitride is a chemical compound of silicon and nitrogen. It is a hard ceramic and is mostly used in high-endurance and high-temperature applications.
Silicon nitride welding pin is made of a high-melting-point ceramic material that is extremely hard and relatively chemically inert. Due to the even performance in high temperature, Si3N4 is a commonly used ceramic material in the metallurgical industry. It has excellent thermal shock resistance due to the microstructure. The creep and oxidation resistance of Si3N4 is also superior, its low thermal conductivity and high wear resistance also make it an outstanding material that can withstand conditions of most industrial applications.
The silicon nitride nozzles and covers have the characteristics of oxidation resistance, high temperature strength and less sputter adhesion, which can prolong the service life of the welding parts.
There are 5 different methods to produce silicon nitride Si3n4 ceramic, including SRBSN, GPSN, HPSN, HIP-SN and RBSN, make the application and working material different slightly. In these 5 methods of production, GPSN is most commonly used to produce Si3N4 components.
2 . Silicon Nitride Welding Pin Application
Silicon nitride welding pin is ideal for applications with high dynamic stresses, thermal rigor, and demanding reliability requirements.
