① Improve the mechanical properties of metal materials or parts. For example: improve the hardness and wear resistance of tools, bearings, etc., improve the elastic limit of springs, and improve the comprehensive mechanical properties of shaft parts.

② Txhim kho cov khoom siv lossis tshuaj lom neeg ntawm qee cov hlau tshwj xeeb. Xws li kev txhim kho corrosion kuj ntawm stainless hlau thiab ua kom cov hlau nplaum ruaj khov ntawm cov hlau nplaum hlau.
