2. Kev Ua Haujlwm Kub Kub: Nrog kev sib ntxiv ntawm cov khoom xws li molybdenum thiab titanium,SB 424 cov ntaub ntawvmuab kev tiv thaiv zoo heev rau oxidation thiab nkag mus ntawm qhov kub siab, ua kom ntseeg tau kev ua tau zoo hauv siab -kub siv.
3. Mechanical Properties: SB 424 alloys muaj cov khoom siv zoo, nrog rau lub zog tensile siab, yield zog, thiab elongation, ua rau lawv tiv taus txhua yam kev ntxhov siab thiab deformation hauv kev xav tau kev ua haujlwm.
4. Weldability: Cov ntaub ntawv no feem ntau yog weldable siv cov txheej txheem vuam, tso cai rau kev tsim cov txheej txheem nyuaj thiab cov khoom yooj yim.
5. Formability: SB 424 cov ntaub ntawv muaj nyob rau hauv daim ntawv ntawm daim hlau thiab coils, muab versatility nyob rau hauv fabrication txheej txheem xws li txiav, dabtsi yog khoov, thiab tsim kom tau raws li cov kev cai tsim.
6. Chemical Compatibility: SB 424 alloys tau sib xws nrog ntau hom kev lag luam tshuaj thiab cov kua dej, kom ntseeg tau ntev -lub sij hawm kev ntseeg siab thiab kev ua tau zoo nyob rau hauv ib puag ncig corrosive.
Hauv kev xaus,ASTM B424 / ASME SB 424Cov txheej txheem txhais cov kev qhia tshwj xeeb rau npib tsib xee- hlau-chromium- molybdenum- tooj liab alloys, suav nrog qib zoo li Alloy 825, Alloy 825HT, thiab Alloy 825LCF. Cov ntaub ntawv no nthuav tawm qhov tshwj xeeb corrosion tsis kam, kev ua haujlwm siab kub, thiab cov khoom siv kho kom zoo, ua rau lawv tsis tuaj yeem nyob hauv ntau qhov kev lag luam uas muaj kev ntseeg siab thiab kav ntev yog qhov tseem ceeb.
