Lub saum npoo tawv ntawm Q345NH ya ya cua hlau phaj yog raws li hauv qab no:
(1) Kev kub siab heev Quenching: Tso Qenching: Tso Q345Nhub Nrog Hlau Hlau Rau Hauv Kev Loj Hlai Loj Hlob thiab Qhib Cov Loj Ntiav Tam Sim No. Nyob rau lub sijhawm no, ntxias tam sim no yuav tsim tawm hauv qhov chaw ua haujlwm. Qhov loj zaus tam sim no tsuas yog muaj feem ntau ntawm cov npoo ntawm Q345Nhre weater steel phaj, yog li ntev li ntev li ntev li ntev li ntawm q345nhow wighching steel phaj yog rhuab. Qhov qauv cua sov thiab quenching yog hu ua kev loj heev induction hardening.
(2) Nplaim Quenching: Qhov no yog kev siv cov pa thiab lwm yam nplaim roj kom nres cua sov quenching.
(3) carburizing thiab quenching: txhawm rau kom nce cov pa roj carbon monoxide q345Nhdow Kua carburizing cov neeg sawv cev xws li cov neeg sawv cev carburizing xws li cov pa hluav ncaig thiab roj coke thiab roj carburizing. Thaum cov cua sov nres nyob rau hauv tus neeg sawv cev carburizing, cov carbon lub caij penetrates mus rau saum npoo ntawm q345Nhre weater steel phaj ua cov pa roj carbon monoxent steel q345Nhhture wights steel phaj. Lub carburizing thiab quenching txheej yuav mus txog ntawm qhov tob hauv millimeter.
