Kev xa khoom

Lub npe Cim Kev piav qhia
Txias tiav (nyuaj) BK (+C) Cov raj tsis tau txais kev kho cua sov tom qab qhov kawg txias txias thiab, yog li, muaj kev tiv thaiv siab heev rau deformation.
Cold tiav (Soft) BKW Kev kho cua sov zaum kawg yog ua raws li kev kos duab txias uas muaj kev txwv tsis pub deformation.Kev tsim nyog ntxiv tso cai rau qee qhov kev ua kom txias (xws li khoov, nthuav dav)
(+ LC)
Txias tiav thiab kev ntxhov siab BKS(+SR) Kev kho cua sov yog siv tom qab lub caij txias kawg.Raws li cov txheej txheem ua haujlwm tsim nyog, qhov nce ntxiv ntawm cov kev ntxhov siab uas cuam tshuam cuam tshuam ua rau ob qho tib si tsim thiab machining mus rau ib qib twg.
Annealed GBK (+A) Cov txheej txheem txias txias kawg yog ua raws li kev sib tsoo hauv qhov chaw tswj tau.
Li qub NBK (+ N) Cov txheej txheem txias txias kawg yog ua raws li los ntawm annealing saum toj kawg nkaus transformation point nyob rau hauv ib qho chaw tswj.
