1. Dab tsi yog cov ntawv thov tseem ceeb ntawm cov ntawv hlau tsis muaj steel thiab npib tsib xee alloy?
Teb:
Cov ntawv no yog siv dav hauv:
Cov khoom siv hauv chav ua noj, kev ua zaub mov, thiab khoom siv
Cov khoom siv tshuaj thiab tshuaj
Marine thiab offshore structures
Architectural thiab hniav panels
Thaum tshav kub kub exchangers thiab siab hlab ntsha
Nickel alloy thiab siab -qib stainless hlau zoo li 904L thiab Inconel yog qhov nyiam rau corrosive lossis siab - qhov kub thiab txias.
2. Dab tsi yog qhov txawv ntawm cov ntawv txias - dov thiab kub - cov ntawv dov?
Teb:
Txias-rolled: Smooth nto, nruj tolerances, zoo mechanical zog, zoo tagnrho rau cov ntaub ntawv meej thiab nyias nyias zoo li 0.3mm.
Kub-rolled: Rougher nto, ntau saj zawg zog thiab ductile, nqi-zoo rau loj-scale structural los yog industrial daim ntaub ntawv.
Nto tiav zoo li 2B (matte) thiab BA (ci annealed) cuam tshuam cov tsos thiab kev xav.
3. Yuav ua li cas corrosion kuj sib txawv ntawm 201, 304, 316, 347, 904L, thiab Inconel nplooj ntawv?
Teb:
201: Economical, nruab nrab corrosion kuj, haum rau sab hauv tsev siv.
304: Zoo heev corrosion kuj; dav siv.
316: Superior corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv marine ib puag ncig.
347: Stabilized stainless hlau; resists intergranular corrosion ntawm qhov kub thiab txias.
904L: High corrosion kuj tiv thaiv acids thiab chlorides.
Inconel: Extreme corrosion thiab kub tsis kam, haum rau tshuaj lom neeg thiab siab -kub muaj kev siv.
4. Puas yog 0.3mm nyias stainless hlau los xij tuaj yeem tsim los yog tsim tau yooj yim?
Teb:
Yog, 0.3mm nplooj ntawv yog hloov tau thiab tuaj yeem ua tau:
Txiav, laser - txiav, los yog xuas nrig ntaus
Khoov, stamped, lossis sib sib zog nqus- kos
Welded nrog TIG lossis laser vuam (nyob ntawm cov hlau)
Txawm li cas los xij, qib siab -nickel lossis qib ruaj khov yuav xav tau cov cuab yeej tshwj xeeb los tiv thaiv kev tawg lossis ua haujlwm nyuaj.
5. Dab tsi yog qhov khaws cia thiab tuav cov lus pom zoo rau cov ntawv hlau stainless thiab npib tsib xee alloy?
Teb:
Khaws rau hauv qhov chaw qhuav, qhov cua kom tsis txhob xeb los yog oxidation.
Khaws cov ntawv sib cais nrog cov ntawv tiv thaiv lossis yas kom tsis txhob khawb.
Tsis txhob sib cuag nrog cov pa roj carbon steel, uas tuaj yeem ua rau muaj kab mob thiab xeb.
Rau qhov ntev - khaws cia ntev, tshawb xyuas ib ntus kom ntseeg tau tias muaj kev ncaj ncees ntawm qhov chaw ua ntej siv.
