Stainless Hlau Vuam Rods

Raws li cov khoom siv vuam tsis tseem ceeb hauv kev tsim khoom, stainless hlau vuam rods tau dhau los ua kev xaiv rau cov neeg yuav khoom vim lawv qhov kev ua tau zoo heev. Cov khoom no belongs rau qeb ntawm chromium-nickel stainless hlau vuam rods, nrog ib tug flux txheej siv titanium-calcium hom los yog alkaline formulation. Cov khoom tseem ceeb muaj 17.0–21.0% chromium thiab 7.5–11.0% npib tsib xee, nrog rau qee cov qauv ntxiv molybdenum los txhim kho corrosion, ua tau raws li cov qauv hauv tebchaws xws li GB / T 983 nrog rau cov qauv thoob ntiaj teb xws li AWS A5.4.

Nyob rau hauv cov nqe lus ntawm specifications, txoj kab uas hla ntawm stainless hlau vuam rods ranges ntawm Φ2.0 mus rau Φ5.0mm, haum rau vuam tam sim no ntawm 40-200A, thiab yuav siv tau nrog AC thiab DC (qee yam alkaline hom yuav tsum tau DC rov qab polarity). Cov hlau tso tawm muaj lub zog tensile ntawm Greater los yog sib npaug rau 550MPa, elongation ntawm ntau dua los yog sib npaug rau 30%, leej faj thiab phosphorus cov ntsiab lus tsawg dua los yog sib npaug rau 0.040%, thiab ib qho ultra- cov pa roj carbon tsawg (C Tsawg dua los yog sib npaug rau 0.08%) kom tiv thaiv kev cuam tshuam ntawm intergranular corrosion. Ntawm lawv, tus qauv A302 tau kuaj lub zog tensile ntawm 650MPa thiab qhov cuam tshuam lub zog ntawm 72J ntawm -30 degree, nrog kev ua tau zoo tshaj li cov qauv kev lag luam.

Cov yam ntxwv ntawm cov khoom yog txawv: ruaj khov arc, qis spatter (tsawg dua los yog sib npaug li 3%), zoo slag tshem tawm, aesthetically pleasing welds, muaj peev xwm vuam nyob rau hauv txhua txoj hauj lwm, thiab haum rau complex ua hauj lwm tej yam kev mob. Lub ntsiab kom zoo dua ntawm stainless hlau electrodes yog nyob rau hauv sib npaug siab zog thiab corrosion kuj, nrog ib tug pitting peev xwm ntau tshaj los yog sib npaug zos rau 350 mV nyob rau hauv 3.5% NaCl tov, ua rau lawv resistant rau acidic thiab alkaline xov xwm. Tsis tas li ntawd, ua ntej - vuam ci tsuas yog yuav tsum tau rau 1 teev ntawm 300 ~ 350 degree, ua kom pom cov txheej txheem muaj zog.

Functionally, cov khoom no tuaj yeem ua tiav cov vuam sib txawv ntawm cov hlau tsis sib xws (xws li stainless hlau thiab carbon hlau), cov phaj sib xyaw, thiab cov hlau quenched, nrog lub hardness nyob rau hauv qhov kev hloov chaw stabilized ntawm 220-240 HV thiab tus nqi dilution tswj ntawm 18-22%, zoo ua kom muaj kev sib koom ua ke ntawm cov txheej txheem.

Nws muaj ntau yam kev siv, npog cov khoom siv tshuaj (tank, pipelines), cov khoom siv ua khoom noj, lub nkoj hull cov qauv, lub tsev railings, cov cuab yeej kho mob, thiab cov khoom siv metallurgical. Nws yog qhov tshwj xeeb tshaj yog tsim rau corrosion-cov qauv vuam ntawm qhov ua haujlwm kub hauv qab 300℃thiab tau raug pov thawj ntau xyoo ntawm kev pabcuam hauv siab -kawg ib puag ncig xws li nuclear fais fab thiab petrochemicals. Kev yuav khoom stainless hlau vuam pas nrig tuaj yeem ua tau raws li cov kev xav tau vuam thoob plaws ntau qhov kev lag luam thaum txo cov nqi txij nkawm tom qab los ntawm kev tswj xyuas kom zoo, ua rau tus nqi - xaiv zoo rau cov khoom siv.
