Kev tsis

904L stainless hlau ntawv yog cov pa roj carbon tsawg, high-nickel, molybdenum austenitic stainless hlau ntawv nrog 14.0-18.0% chromium, 24.0-26. 0% nickel thiab 4.5% molybdenum. Qhov sib ntxiv ntawm cov ntsiab lus tooj liab muab nws lub zog acid tsis kam.

Thaum soaked nyob rau hauv diluted tov ntawm sulfuric acid, SS 904L daim ntawv sawv cev zoo heev corrosion kuj. Nws muaj qib siab ntawm kev tiv thaiv tshwj xeeb rau chloride interstitial corrosion thiab kev ntxhov siab corrosion chipping. Etching me ntsis thiab cov kab nrib pleb tsis tshwm sim yooj yim, thiab nws cov kev tiv thaiv rau pitting corrosion yog me ntsis ntau dua li lwm qib steel. Vim tias 904L stainless hlau ntawv muaj cov pa roj carbon tsawg dua, yuav tsis muaj carbide nag lossis daus thaum lub sijhawm kho cua sov thiab vuam. Qhov no txo qhov muaj peev xwm rau intergranular corrosion thaum kev kho cua sov thiab vuam.

904L stainless hlau ntawv muaj cov qauv austenitic kiag li; Tsis zoo li lwm cov austenitic stainless hlau uas muaj cov ntsiab lus molybdenum siab, hom ntawv hlau no tsis raug rau ferrite thiab alpha theem nag lossis daus. Cov ntawv hlau no muaj peev xwm ua kom zoo-passivation transformation, machinability thiab weldability, kub workability xws li stamping thiab dabtsi yog khoov. Yuav tsis muaj kev kho cua sov hardening phenomena. SS 904L daim ntawv yog dav siv nyob rau hauv cov tshuaj, kev tsim kho, khoom noj khoom haus, marine thiab kev kho mob industries, thiab lwm yam.

TS muaj cov khoom siv hlau tshwj xeeb thiab cov khoom tshwj xeeb steel, suav nrog cov ntawv hlau tsis muaj steel hlau ua los ntawm 201, 202, 304, 304L, 316, 316L, 403, 430, 904L, thiab lwm cov ntawv ntawm tib hom. Peb cov ntawv SS 904L tuaj yeem tsim kho, txiav, thiab ua tiav kom tau raws li qhov xav tau ntawm peb cov neeg siv khoom. Cov nplooj ntawv no yog tsim los ntawm cov khoom zoo stainless hlau raw khoom. Thov so kom paub tseeb tias cov khoom yuav ua tau raws li qhov xav tau ntau lawm, qhov zoo ntawm cov khoom yuav raug kuaj, lub peev xwm yuav loj, thiab pab pawg muag khoom yuav saib xyuas tag nrho cov txheej txheem rau koj!

Weldability ntawm 904L stainless hlau ntawv

904L stainless hlau ntawv, zoo li zoo tib yam stainless hlau, tuaj yeem welded siv ntau yam txheej txheem vuam. Rau phau ntawv arc vuam lossis inert gas shielded vuam, vuam pas nrig lossis hlau hlau yog xaiv raws li cov khoom siv hauv paus muaj pes tsawg leeg nrog rau qhov siab dua purity thiab molybdenum cov ntsiab lus xav tau. Preheating feem ntau tsis tsim nyog ua ntej vuam. Tab sis nyob rau hauv cov huab cua txias, kom tsis txhob condensation ntawm dej vapor, lub sib koom cheeb tsam los yog nyob ze cheeb tsam yuav tsum uniformly rhuab.

Nws yuav tsum tau muab sau tseg tias, nyob rau hauv kev sib tw kom tsis txhob carbon aggregation thiab intergranular corrosion, qhov kub yuav tsum tsis txhob ntau tshaj 100 degree. Vuam yuav tsum tau ua hauj lwm thaum muaj ib qho kev xav tau rau ib tug tsawg linear zog nrog rau kev nruam thiab ceev vuam tus nqi. Kev kho cua sov feem ntau tsis tas yuav tsum tau tom qab vuam; Txawm li cas los xij, yog tias xav tau kev kho cua sov, nws yuav tsum tau muab rhaub rau 1100-1150 degree tom qab txias ceev.

Machinability ntawm 904L stainless hlau ntawv

904L stainless hlau daim ntawv lub zog machining zoo ib yam li lwm yam austenitic stainless hlau, nrog ib tug nyiam lo rau lub cutter thiab ua hardened thaum lub sij hawm txiav. Txhawm rau zam cov xwm txheej no, peb yuav tsum siv cov cuab yeej zoo hauv pem hauv ntej-lub kaum sab xis carbide, ntxiv nrog cov khoom siv txias ua los ntawm cov roj sulfur lossis cov roj chlorinated.
