Roj Quenching thiab Tempering zoo li tus caij nplooj ntoos hlav Steel hlau 65mn 60SI2MNA 55CRSI SAE9254V 50CRVA
Zoo li tus tshwj xeeb steel hlau (hexagonal hlau)
siv
Cov khoom no yog muaj feem xyuam rau qhov yam ntxwv thiab bolts, ceev thiab lwm cov hlau hexagonal

Deg zoo:
Ntawm cov hlau steel yuav tsum du thiab tsis txhob tsis xws luag xws li tej kab nrib pleb, xeb, folds, pob, lwm yam uas yuav adversely rau txoj kev siv, tab sis yuav tsum tso cai muaj ntawm ib teev anisotropic thiab cov neeg khawb thiab qho to tsis tshaj ib tug ib nrab ntawm qhov seem kam rau ua.
Txheej decarburization:
(Ferrite + txoj kev hloov txheej) qhov tob ntawm hlau tsis tshaj hexagonal nominal nrug 1.0% ntawm sab,
Txoj kev siv:
Tus hlau written li ib kauj
Nrog kev dav thiab kev txawj ntse, phooj ywg hlau yog nrog tus tsim, manufacturing thiab ua li cov roj quenching thiab tempering zoo li tus caij nplooj ntoos hlav hlau hlau 65mn 60si2mna 55crsi sae9254v 50crva ASTM-A230-99, ASTM-A401, EN10270-2, JIS G3561. Ua ib tug neeg chaw tsim tshuaj paus, peb tam sim no theem koj zoo ntau yam steel nyob ntawm tej hauv Suav teb uas tawm hauv siab zog, toughness zoo thiab zoo hnav ua hauj. Los peb txais tos koj txog customized.
Cim npe nrov: roj quenching thiab tempering zoo li tus caij nplooj ntoos hlav ntxaij hlau 65mn 60SI2MNA 55CRSI SAE9254V 50CRVA Tuam Tshoj, chaw tsim tshuaj paus, Mekas, ua rau Suav teb
