Piv nrogzoo tib yam hlau, Tshwj xeeb hlau muaj lub zog siab dua thiab kev muaj zog, cov khoom siv lub cev, tshuaj lom neeg, biocompatibility thiab cov txheej txheem kev ua tau zoo. Tab sis tshwj xeeb hlau muaj qee cov yam ntxwv sib txawv los ntawm cov hlau dog dig. Rauzoo tib yam hlauCoob tus neeg muaj kev nkag siab ntau dua, tab sis rau cov yam ntxwv ntawmTshwj Xeeb Hlau, Coob leej ntau tus neeg tau hais tsis meej pem. Yog li, tshooj lus hauv qab no tsom rau cov yam ntxwv tshwj xeeb.
Nta ntawm cov hlau tshwj xeeb:
Piv nrogzoo tib yam hlau, Tshwj xeeb hlau muaj cov yam ntxwv ntawm kev siab siab, kev sib dhos siab, ultra-nplua qauv thiab siab precision:
(1) kev coj dawb huv.Cov ntsiab lus ntawm cov roj thiab suav nrog (suav nrog cov hlau tso nrog nrog cov khoom me me qis) hauv cov hlau tuaj yeem txo. Thaum lub purity ntawm cov hlau yog nce rau qee qhov kev txwv, tsis yog tsuas yog txhim kho cov hlau tuaj yeem txhim kho, tab sis kuj yog cov khoom tshiab ntawm cov hlau tuaj yeem ua tau zoo. Piv txwv li, cov pa cov pa hauv cov kabmob hlau raug txo los ntawm kev txo los ntawm 30 × 10-6 mus rau 5 × 10-6, thiab cov kev coj lub neej nce 30 zaug. Universal Austenitic stainless hlau yog lub cev tsis ntxhov corrosion thaum cov ntsiab lus phosphorus yog txo rau 3 × 10-6. Qhov kawg ntawm lub xyoo pua 20, kev ua kom tiav qib (10) ntawm cov hlau uas tuaj yeem ua tiav los ntawm pawg ntau lawm yog: ourrogen ≤ [15, phosphorus ≤25.

(2) cov khaub ncaws loj.Cov neeg sib cav sib ceg ntawm cov qauv hlau ua rau cov qauv tsis sib xws thiab cov khoom ntawm cov laj thawj tseem ceeb rau thaum pib tsis ua haujlwm ntawm cov khoom muaj peev xwm ntawm cov hlau. Niaj hnub nim ntau lawm tshuab yuav tsum ua kom cov uniformity ntawm cov hlau ncav cuag: iav hlau steel nyuaj kev hloov pauv yog ± 3HRC; Cov ntsiab lus ntawm cov carbon, npib tsib xee, molybdenum ≤ ≤ ≤ ≤ ± ≤ ± ≤ ± 0.01% thiab chromium ≤ ± ≤ ≤ ≤ AN ≤ ≤. 0.02% tau tswj hwm ncaj qha. Cov noob nplej loj ntawm kev coj tus kabmob hlau tom qab quenching yog spherical thiab qhov loj hloov yog 0.8 ± 0.2 μm. Cov khoom siv tshuab ntawm laminated ntawm lub kua muag resistant hlau (Z-kev taw qhia steel
(3) ultra-nplua qauv.Ultra-nplua microstructure ntau zog yog qhov tsuas yog dag zog siv hluav taws xob uas tuaj yeem ua kom lub zog ntawm cov hlau tsis muaj zuj zus lossis me ntsis nce qib. Piv txwv li, thaum lub noob uas muaj zog ntawm lub zog ntawm 60μm rau 2.3 μm, qhov kev nyuaj siab tau nce los ntawm 100 mus rau 220mpa · m. Lub irradiated embrittlement kub ntawm cov coarse-grashed steel phaj nyob rau hauv nuclear reactor siab ntsha yog 150 ~ 250 ℃ Thaum twg ntawm cov hlau nplua yog 50 ~ 70 ℃. Thaum lub carbide loj hauv bear steel yog nplua rau ≤0.5μm, lub neej ris tsho yuav tau zoo heev.
(4) qhov ntsuas siab.Cov hlau tshwj xeeb yuav tsum muaj qhov chaw zoo nto thiab nqaim sab hauv. Qhov tseeb ntawm kub dov steel qws yog li cas rau ± 0.1mm, cov tuab tuab siv ntawm cov kab colled txias coil yog li ± 0.003mm.
