Cov hlau tsis xeb duplex, uas paub zoo txog lawv cov kev sib xyaw ua ke ntawm austenitic thiab ferritic cov yam ntxwv, sawv cev rau qhov kev hloov pauv ntawm metallurgy, muab kev sib koom ua ke ntawm cov txiaj ntsig thaum txo cov teeb meem uas muaj nyob hauv, feem ntau ntawm tus nqi sib tw.
Nkag Siab Txog Duplex Stainless Steel:
Lub hauv paus tseem ceeb ntawm cov hlau duplex stainless hlau yog nws cov qauv microstructure dual-phase, feem ntau muaj kev sib xyaw ua ke ntawm austenite thiab ferrite, tsim kom muaj kev sib koom ua ke ntawm cov yam ntxwv zoo thaum txo qhov tsis muaj zog. Cov khoom sib xyaw ua ke ntawm cov hlau, txawm hais tias nyob ntawm qib tshwj xeeb, feem ntau suav nrog carbon, manganese, silicon, chromium, nickel, phosphorus, thiab sulfur, nrog rau cov khoom ntxiv xws li molybdenum, nitrogen, thiab tooj liab ntxiv txhim kho cov khoom siv.
Keeb Kwm ntawm Duplex Stainless Steel:
Lub hauv paus chiv keeb ntawm cov hlau duplex stainless hlau tau pib los ntawm kev xav txog kev xav hauv xyoo 1920, thiab xaus rau hauv kev tsim khoom lag luam thaum xyoo 1930. Thaum pib tsuas yog siv rau kev tsim khoom cam khwb cia thiab cov ntawv thov tshwj xeeb vim muaj cov pa roj carbon ntau, kev nce qib hauv kev decarburization thaum xyoo 1960s tau tshaj tawm lub sijhawm tshiab, pab txhawb kev tsim cov hlau qis-carbon nrog cov ntsiab lus chromium thiab nickel zoo tshaj plaws, yog li ua kom zoo dua qhov sib npaug ntawm ferrite thiab austenite. Lub cim ntawm txoj kev hloov pauv no yog Duplex 2205, ib qho hlau ua ntej los ntawm nruab nrab xyoo 1970s uas tseem muaj txiaj ntsig vim nws qhov kev tiv thaiv corrosion zoo dua piv rau cov qib austenitic ib txwm muaj.
Cov txiaj ntsig ntawm Duplex Stainless Steel:
Txawm hais tias yog ib feem me me ntawm kev lag luam stainless hlau, duplex alloys muab ntau yam zoo dua li cov austenitic thiab ferritic ib txwm muaj. Qhov tseem ceeb ntawm cov txiaj ntsig no yog lub zog siab dua, kev tawv dua, thiab kev yoog tau, nrog rau kev tiv thaiv corrosion tshwm sim ua lub cim tseem ceeb, sib tw, yog tias tsis dhau, ntawm cov qib austenitic. Ntxiv mus, qhov pheej yig hauv duplex steel, vim yog kev siv cov khoom sib xyaw ua ke zoo, ua rau nws yog qhov kev xaiv zoo thoob plaws ntau yam kev siv.
Cov ntawv thov ntawm Duplex Stainless Steel:
Qhov ua tau ntau yam ntawm cov hlau duplex stainless hlau pom tau zoo thoob plaws ntau yam lag luam thiab thaj chaw, vim nws tiv taus xeb zoo heev, muaj zog dua, thiab tus nqi tsim nyog. Feem ntau, kev ua haujlwm hauv hiav txwv thiab ze ntug dej hiav txwv, suav nrog kev khawb roj, kev lim dej ntsev, thiab kev kho dej, sawv cev rau cov neeg tau txais txiaj ntsig zoo ntawm cov hlau duplex lub peev xwm. Ib yam li ntawd, nws cov txiaj ntsig txuas mus rau kev ua tshuaj lom neeg, kev siv hauv dej hiav txwv, cov khoom siv tswj kev ua qias tuaj, thiab kev siv zog tsim kho, qhia txog nws qhov muaj nyob txhua qhov chaw hauv cov toj roob hauv pes niaj hnub no.
