304/304L Stainless Hlau Tube
Kev piav qhia
ASTM A312 ASTM A269 ASME SA 213 / ASTM A213 TP304, EN 10216-5 1.4301 stainless hlau yog variation ntawm 18% chromium - 8% nickel austeniticstainless steel raj, feem ntau paub thiab nquag siv tsev neeg hlau.Qhov no stainless hlau raug txiav txim siab rau ntau yam ntawm daim ntawv thov zoo corrosion kuj, yooj yim fabrication, zoo heev formability, thiab siab zog nrog tsawg yuag.
304 Stainless Hlau yog tus qauv "18/8" stainless hlau;nws yog ntau yam thiab feem ntau siv stainless hlau, muaj nyob rau hauv ib tug ntau yam ntawm cov khoom, cov ntaub ntawv thiab finishes tshaj 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 yog yooj yim nres lossis yob tsim rau hauv ntau yam khoom siv rau kev siv hauv kev lag luam, kev tsim vaj tsev, thiab kev thauj mus los.Qib 304 kuj muaj cov yam ntxwv zoo heev ntawm vuam.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 siv dav hauv cov khoom 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 cryogenictemperature.
