ASTM A312 yog cov qauv txheem kev tawm tsam los ntawm cov neeg Asmeskas haiv neeg rau kev sim thiab cov ntaub ntawv (SETM)
** Cov ntsiab lus tseem ceeb: **
- ** TSIS YOG qeb ** AVTM A312 nws tus kheej yog ** tsis yog qib ** tab sis tus qauv uas muaj ntau cov qauv hlau.
- ** Cov qib kawm hauv A312 **: Cov qib kawm uas muaj nyob hauv cov kev qhia tshwj xeeb no suav nrog:
- ** ** TPP04 ** (Txheem 304 stainless hlau)
- ** TPP04L ** (Tsawg-AVBO 304)
- ** Tp316 ** (Molybdenum-ua kom zoo rau corrosion tsis kam)
- ** Tp316L ** (Tsawg-Carbon 316)
- ** Tp321 ** (Titanium-stabilized)
- ** Tp347 ** (Niobium-stabilized)
- Thiab lwm tus (piv txwv li (309, 310, 317, 904L).
- ** Naming Countress **: Daim ntawv qhia txog cov khoom siv thiab qib A316l **, ** Qhov twg "Ntaus" lossis "Tube" lossis "Tube"
** Hom phiaj **: Cov kav dej no tau siv rau hauv cov ntawv thov ua kom xeb, ntsuas qhov hnyav, xws li siv tshuaj lom neeg siv tshuaj, roj thiab hluav taws xob.
Hauv cov ntsiab lus, ASTM A312 txhais cov cai rau cov kav hlau steel, thaum tus lej ** (piv txwv li, 304, 316) qhia txog cov muaj ntau yam thiab cov khoom.
