In the precision manufacturing of vacuum chambers and critical components for semiconductor, display panel, and scientific research applications, material performance is paramount. Liquid nitrogen cryogenic treatment represents one of the most sophisticated metallurgical processes in Leiku Semiconductor's advanced manufacturing arsenal.
This specialized treatment involves cooling metal components to ultra-low temperatures (approximately -196°C) using liquid nitrogen in a carefully controlled environment. At these extreme temperatures, remarkable transformations occur within the metal's microstructure: retained austenite converts to martensite, microscopic carbides precipitate uniformly, and internal stresses are relieved.
The benefits for high-performance components are substantial:
- Enhanced hardness: Increases by 10-15% compared to conventional heat treatments
- Superior wear resistance: Up to 300% improvement in service life for critical components
- Dimensional stability: Minimizes warping and distortion during subsequent manufacturing processes
- Improved fatigue resistance: Enhanced ability to withstand cyclic loading
- Reduced micro-cracking: Critical for high-vacuum applications where integrity is essential
At Leiku Semiconductor, we implement cryogenic treatment as part of our integrated manufacturing approach for components requiring exceptional mechanical properties and vacuum performance. This process is particularly valuable for stainless steel chambers, precision fixtures, and components subject to mechanical
