ASTM A312 TP304 Stainless Hlau Yeeb Nkab Khoom thiab Cwj Pwm
304 Stainless Hlau yog tus qauv "18/8" stainless hlau. Nws yog cov khoom siv ntau yam thiab feem ntau siv stainless hlau, muaj nyob rau hauv ntau yam ntawm cov khoom, cov ntaub ntawv thiab tiav dua li lwm yam. Nws muaj kev sib sau zoo heev thiab vuam yam ntxwv. Qhov sib npaug austenitic qauv ntawm Qib 304 ua rau nws sib sib zog nqus nqus heev yam tsis muaj qhov nruab nrab annealing, uas tau ua rau qib no tseem ceeb hauv kev tsim cov khoom siv hlau tsis zoo xws li dab dej, hollow-ware thiab saucepan. Rau cov ntawv thov no nws yog ib txwm siv tshwj xeeb "304DDQ" (Drawing Zoo) ntau yam.
Qib 304 Yeeb Nkab yog yooj yim nres lossis yob tsim rau hauv ntau yam khoom siv rau kev siv hauv kev lag luam, vaj tsev, thiab kev thauj mus los. Qib 304 kuj muaj cov yam ntxwv vuam zoo heev. Post-weld annealing tsis tas yuav tsum tau thaum vuam nyias ntu.
Qib 304L, qis carbon version ntawm 304, tsis xav tau tom qab vuam annealing thiab yog li feem ntau siv hauv cov ntsuas hnyav (dhau li 6 hli). Qib 304H nrog nws cov ntsiab lus carbon siab dua pom daim ntawv thov ntawm qhov kub siab. Cov qauv austenitic kuj muab cov qhab nia zoo heev, txawm tias mus rau qhov kub thiab txias.
ASME SA213 TP304 Stainless Hlau Daim Ntawv Thov
TP304 Stainless Hlau yog siv rau ntau yam kev lag luam.
Daim ntawv thov yog: kub exchangers, condensers, pipelines, txias thiab cua sov coils nyob rau hauv cov tshuaj, petrochemical, chiv, pulp thiab ntawv thiab nuclear fais fab kev lag luam, raws li zoo raws li nyob rau hauv zus tau tej cov tshuaj, zaub mov thiab dej haus.
