Cov Ntawv Thov
Qeb A:Cov qib no feem ntau yog siv rau hauv cov hom phiaj dav dav uasYuav tsum muaj lub zog nruab nrabCov. Nws yog qhov tsim nyog rau cov qauv tsis yog qhov ua tau zoo uas uaTsis tas yuav tsum muaj cov ris nra hnyavMuaj peev xwm.
Qib B:Qib B yog dav siv hauv kev tsim kho choj, bolted qauv kev tsim, thiab riveted qauv vim nwsSiab zog thiab cov khoom siv zooCov. Nws yog qhov zoo tagnrho rau kev tsim cov ntas rau cov tshuab loj thiab cov qauv zoo nkauj ntawm lub dav hlau, qhov twg muaj zog yog tsim nyog los tiv thaiv lub siab thiab hnyav.
Qib C:Qib C yog paub los siv rau hauv cov ntawv thov uasyuav tsum muaj lub zog loj dua qib bCov. Cov qib qib no feem ntau tau teev rau cov txheej txheem txheej txheem hnyav uas muaj peev xwm loj tshaj plaws yog qhov tseem ceeb.
Qhov Zoo
Qeb A:MuajSib npaug ntawm lub zog thiab ductility, ua rau nws versatile ntau yam ntawm cov ntawv thov. Nws kuj tseem siv tau ntau dua li siv tau ntau dua rau cov qhab nia siab dua vim nws cov kev yuav tsum tau muaj zog.
Qib B:Nwssiab lub zog, zoo weldability, thiab corrosion tsis kamUa rau nws muaj cov khoom siv tsis tseem ceeb hauv kev tsim kho choj thiab lwm cov ntawv thov hnyav. Muaj kev muaj ntawm ntau cov duab thiab kev tsim cov txheej txheem ua kom paub meej lub zog thiab ua tau zoo.
Qib C:Tej zaum, qib C muabLub zog tshaj plaws ntawm peb qib, muab cov khoom siv zoo dua-cov kabmob kev siv peev rau cov ntawv thov tseem ceeb.
Hauv cov ntsiab lus, Astm A501 Qib A, B, thiab C sib txawv rau lawv cov ntawv thov, qhov zoo thiab qhov tseem ceeb.Qib A yog ntau yam rau kev siv dav dav, qib B yog qhov tseem ceeb rau cov qauv coj ua hnyav, thiab qib C yog qhov tseem ceeb rau cov ntawv thov feem ntau. Txhua qib ua lub luag haujlwm tshwj xeeb hauv kev tsim kho thiab kev lag luam engineering, yog li txhim kho kev nyab xeeb, ua haujlwm tau zoo, thiab cov qauv txheej txheem kev ntseeg.
