Npuab, soaking. Cov bolts yog nyob rau ntawm qhov kub no rau ib lub sijhawm, tso cai rau cov qauv sab hauv kom ruaj khov thiab ua kom zoo.
Thaum ntawd, quenching. Cov bolts tau txias sai, ua rau lawv lub hardness thiab lub zog. Ceev faj tswj yog qhov tseem ceeb los tiv thaiv kev deformation.
Kawg no, Kev tu, kom qhuav, thiab zoo kev tshuaj xyuas kom cov bolt cov qauv kev ua tau zoo, txhim kho lawv cov kev ua haujlwm ruaj khov thiab kev ntseeg tau hauv kev ua haujlwm hnyav.
