Lub Corrosion Resistance Ntawm Stainless Steel Feem ntau nyob ntawm

Qhov saum npoo ntawm stainless hlau phaj yog du thiab huv si, nrog high plasticity, toughness thiab mechanical zog, thiab nws yog resistant rau corrosion ntawm acids, alkaline gases, kev daws teeb meem thiab lwm yam xov xwm. Nws yog cov hlau alloy uas tsis xeb yooj yim, tab sis nws tsis yog xeb-dawb kiag li. Stainless hlau phaj hais txog lub phaj hlau uas tiv taus corrosion los ntawm cov xov xwm tsis muaj zog xws li cua, chav dej thiab dej, thaum acid-resistant steel phaj hais txog cov hlau phaj uas tiv taus corrosion los ntawm chemically corrosive media xws li kua qaub, alkali thiab ntsev. Stainless hlau phaj tau nyob ib ncig ntawm ntau tshaj ib puas xyoo txij li thaum nws tau tawm thaum pib ntawm lub xyoo pua 20th century. Stainless hlau phaj feem ntau yog ib lo lus dav dav rau stainless hlau phaj thiab acid-resistant steel phaj. Stainless hlau phaj hais txog lub phaj hlau uas tiv taus corrosion los ntawm cov xov xwm tsis muaj zog xws li cua, chav dej thiab dej, thaum acid-resistant steel phaj hais txog cov hlau phaj uas tiv taus corrosion los ntawm chemically corrosive media xws li kua qaub, alkali thiab ntsev. Txij li thaum lub advent ntawm stainless hlau phaj nyob rau hauv thaum pib ntawm lub xyoo pua no, txoj kev loj hlob ntawm stainless hlau phaj tau nteg ib tug tseem ceeb cov ntaub ntawv thiab technical foundation rau txoj kev loj hlob ntawm niaj hnub kev lag luam thiab scientific thiab technologies. Muaj ntau hom stainless hlau daim hlau, nrog rau cov khoom sib txawv, thiab nws tau maj mam tsim ntau pawg hauv txoj kev loj hlob. Raws li cov qauv tsim, nws tuaj yeem muab faib ua plaub pawg: austenitic stainless hlau phaj, martensis stainless hlau phaj (xws li nag lossis daus hardening stainless hlau phaj), ferritic stainless hlau phaj, thiab austenitic thiab ferritic duplex stainless hlau phaj. Raws li cov tshuaj muaj pes tsawg leeg hauv cov hlau phaj lossis qee cov yam ntxwv hauv cov phaj hlau, nws tau muab faib ua chromium stainless hlau phaj, chromium-nickel stainless hlau phaj, chromium-nickel-molybdenum stainless hlau phaj, qis carbon stainless hlau phaj. , high-molybdenum stainless hlau phaj, high-purity stainless hlau phaj, thiab lwm yam raws li cov yam ntxwv ntawm kev ua tau zoo thiab siv cov hlau daim hlau, lawv muab faib ua nitric acid resistant stainless hlau daim hlau, sulfuric acid resistant stainless hlau daim hlau, pitting corrosion resistant stainless hlau phaj. steel daim hlau, kev nyuaj siab corrosion resistant stainless hlau daim hlau, high-strength stainless hlau daim hlau, thiab lwm yam. steel daim hlau, superplastic stainless hlau daim hlau, thiab lwm yam. Tam sim no, feem ntau siv kev faib tawm yog cais raws li cov yam ntxwv ntawm microstructure ntawm cov hlau phaj, cov yam ntxwv ntawm cov tshuaj muaj pes tsawg leeg ntawm cov hlau phaj thiab kev sib xyaw ntawm ob. Feem ntau, nws tau muab faib ua martensitic stainless hlau phaj, ferritic stainless hlau phaj, austenitic stainless hlau phaj, duplex stainless hlau phaj thiab nag lossis daus hardening stainless hlau phaj, thiab lwm yam, los yog muab faib ua ob pawg: chromium stainless hlau phaj thiab nickel stainless hlau phaj. . Kev siv cov khoom siv: cov khoom siv pulp thiab ntawv, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv dyeing, cov khoom siv ua yeeb yaj kiab, cov kav dej, cov khoom siv sab nrauv rau cov tsev nyob hauv ntug hiav txwv dej, thiab lwm yam. Raws li txoj kev tsim khoom, nws muab faib ua ob hom kub dov thiab txias. dov, nrog rau nyias txias phaj nrog lub thickness ntawm 0.5.10-885 hli 72938 thiab nruab nrab thiab hnyav phaj nrog lub thickness ntawm 4.5-100 hli. Nws yuav tsum tau tiv thaiv corrosion ntawm ntau yam acids xws li oxalic acid, sulfuric acid-hlau sulfate, nitric acid, nitric acid-hydrofluoric acid, sulfuric acid-copper sulfate, phosphoric acid, formic acid, acetic acid, thiab lwm yam. dav siv nyob rau hauv tshuaj, khoom noj, tshuaj, papermaking, roj av, atomic zog thiab lwm yam industries, raws li zoo raws li ntau yam thiab Cheebtsam ntawm kev tsim kho, kitchenware, tableware, tsheb, thiab cov khoom siv hauv tsev. Txhawm rau kom ntseeg tau tias cov khoom siv hluav taws xob xws li lub zog tawm los, lub zog tensile, elongation thiab hardness ntawm ntau yam stainless hlau daim hlau ua tau raws li qhov yuav tsum tau ua, cov hlau phaj yuav tsum tau annealed, tshuaj kho, kev laus kho mob thiab lwm yam kev kho cua sov ua ntej xa 05.{{ 25}}.57.29.38 ib. Kev tiv thaiv corrosion ntawm stainless hlau yog nyob ntawm nws cov alloy muaj pes tsawg leeg (chromium, nickel, titanium, silicon, aluminium, manganese, thiab lwm yam) thiab nws cov qauv sab hauv. Raws li txoj kev tsim khoom, nws muab faib ua ob hom kub dov thiab txias dov.
