Cov kav dej thiab cov raj muaj nyob rau hauv interchangeably siv nyob rau hauv industrial daim ntaub ntawv. Txoj kev zoo tshaj plaws uas cov kev lag luam tau faib cov kua dej ntawm cov ntawv thov yog nrog kev pab ntawm cov tubular seem ntawm cov kav dej. Qhov no yog qhov zoo tshaj plaws los muab tag nrho cov roj thiab cov kua dej uas muaj. Cov yeeb nkab yog cov hollow seem uas yog siv rau hauv daim ntawv thov nrog lub voj voog hla ntu uas xa cov khoom yooj yim. Qhov ntev thiab txoj kab uas hla ntawm cov yeeb nkab tau sau tseg raws li daim ntawv thov uas nws siv.
SS 304 alloy steel yog siv rau hauv kev tsim cov yeeb nkab thiab cov raj. Txawm li cas los xij, cov hlau yog tsim los ntawm chromium thiab nickel cov ntsiab lus uas muab cov kav dej thiab cov kav dej ntau yam khoom. Ntxiv rau qhov no, SS 304L yog cov ntsiab lus carbon tsawg dua li 304 alloy hlau. Qhov no yog txoj hauv kev uas nws yog qhov zoo ntawm kev muaj peev xwm ntawm intergranular corrosion kuj. Nyob rau hauv tib txoj kev, SS 304H yog daim ntawv thov kub-kub siv alloy uas nyob ntawd nrog lub zog kub thiab muaj peev xwm ua haujlwm hauv qhov kub siab.
Lub alloy yog vim li casSS 304 / 304L / 304H Tubes & Tubesmuaj cov khoom sib txawv. Qee cov khoom uas cov kav dej thiab cov kav dej muaj cov khoom tiv thaiv corrosion, zoo ductility, durability, stability nyob rau hauv siab kub, thiab zoo toughness.
