SPV 450 puas tuaj yeem siv rau hauv cov tshuab hluav taws xob nuclear?
SPV 450 feem ntau tsis yog siv nyob rau hauv nuclear reactors, vim nws tsis yog optimized rau hluav taws xob-cov khoom tiv thaiv. Nuclear reactor cov ntaub ntawv xav tau cov hlau tshwj xeeb uas muaj zog tiv thaiv hluav taws xob ntau dua -induced embrittlement thiab corrosion. Cov ntaub ntawv zoo li SA-516 lossis lwm yam alloys tsim los rau kev siv nuclear yog qhov tsim nyog rau cov hlab ntsha siab dua.
SPV 450 ua haujlwm li cas hauv siab?
SPV 450 yog tsim los ua haujlwm zoo nyob rau hauv siab -xwm txheej. Nrog rau lub zog tensile ntawm 450 MPa, nws muaj peev xwm tuav cov kev ruaj siab nyob rau hauv cov kev siv tseem ceeb xws li cov hlab ntsha siab thiab cov khoom siv hluav taws xob. Nws zoo heev creep kuj ua kom ntev -lub sij hawm stability txawm nyob rau hauv lub siab heev.
