ASTM A179 yog cov yeeb nkab steel qauv tsim los ntawm American Society for Testing and Materials (ASTM) thiab feem ntau yog siv rau hauv kev tsim cov khoom siv siab xws li chav turbines. Cov yeeb nkab steel no yog ua los ntawm cov pa roj carbon zoo lossis hlau alloy thiab yog tsim los ntawm cov txheej txheem kub dov lossis txias txheej txheem. Nws muaj qhov zoo ntawm lub zog siab, siab ua haujlwm siab, thiab corrosion kuj.
ASTM A179 seamless steel yeeb nkab muaj ntau yam specifications. Raws li kev siv ntau zaus thiab cov cuab yeej siv, cov kav hlau uas muaj cov kab sib txawv thiab cov phab ntsa tuab tuaj yeem xaiv tau. Piv txwv li, "19.05 * 2.11" nyob rau hauv qhov piv txwv no txhais tau hais tias sab nraud txoj kab uas hla ntawm seamless steel yeeb nkab yog 19.05 nti thiab phab ntsa thickness yog 2.11 nti.
ASTM A179 seamless steel kav yuav tsum tau mus los ntawm ntau yam txheej txheem thaum lub sij hawm tsim cov txheej txheem, xws li billet npaj, dov, straightening, tshav kub kev kho mob, pickling, soj ntsuam, thiab lwm yam. Vim nws lub zog siab, siab kub kuj thiab corrosion kuj, kev nyab xeeb thiab ruaj khov ntawm cov cuab yeej tuaj yeem ua kom ntseeg tau. Piv txwv li, nyob rau hauv chav turbines, hom steel yeeb nkab no tuaj yeem tiv taus qhov yaig thiab cuam tshuam ntawm qhov kub thiab txias siab, ua kom cov khoom siv ua haujlwm ib txwm muaj.
