Duplex stainless hlau, muaj npe nrov rau lawv cov kev sib xyaw ua ke ntawm austenitic thiab ferritic zoo, sawv ua ib qho pov thawj rau kev hloov pauv ntawm cov hlau, muab kev sib koom ua ke ntawm qhov zoo thaum txo qis qhov tsis zoo, feem ntau ntawm tus nqi sib tw.
Nkag siab Duplex Stainless Hlau:
Lub hauv paus rau lub ntsiab lus ntawm duplex stainless hlau yog nws ob-theem microstructure, feem ntau muaj qhov sib npaug ntawm austenite thiab ferrite, ua rau muaj kev sib koom ua ke ntawm cov yam ntxwv zoo thaum txo qis qhov tsis zoo. Lub metallurgical muaj pes tsawg leeg, txawm hais tias muaj nyob rau hauv cov qib tshwj xeeb, feem ntau suav nrog carbon, manganese, silicon, chromium, npib tsib xee, phosphorus, thiab sulfur, nrog rau kev xaiv ntxiv xws li molybdenum, nitrogen, thiab tooj liab ntxiv refining cov khoom siv.
Cov ntsiab lus keeb kwm ntawm Duplex Stainless Hlau:
Lub hauv paus ntsiab lus ntawm duplex stainless alloys taug qab mus rau theoretical musings nyob rau hauv 1920s, culminating nyob rau hauv tangible ntau lawm ventures nyob rau hauv lub 1930s. Thaum xub thawj raug txwv rau kev tsim cov cam khwb cia thiab cov ntawv tshwj xeeb vim cov ntsiab lus siab carbon, kev nce qib hauv decarburization los ntawm lub xyoo 1960s tau tshaj tawm lub sijhawm tshiab, txhawb kev sib xyaw ntawm cov pa roj carbon tsawg nrog cov ntsiab lus chromium thiab nickel optimized, yog li refining qhov sib npaug ntawm ferrite thiab austenite. Emblematic ntawm no evolutionary trajectory yog Duplex 2205, ib tug pioneering alloy los ntawm nruab nrab-1970s uas txuas ntxiv hais kom ua qhov tseem ceeb vim nws superior corrosion kuj vis-à-vis pa austenitic qib.
Qhov zoo ntawm Duplex Stainless Hlau:
Txawm hais tias tsim ib feem me me ntawm kev ua lag luam stainless hlau, duplex alloys muaj qhov zoo ntawm qhov zoo vis-à-vis tsoos austenitic thiab ferritic counterparts. Qhov tseem ceeb ntawm cov txiaj ntsig no yog qhov ua kom muaj zog, ua kom muaj zog, thiab ductility, nrog corrosion kuj tshwm sim raws li ib tug feature, kev sib tw, yog tias tsis tshaj, ntawm qib austenitic. Ntxiv mus, tus nqi-kev ua tau zoo muaj nyob rau hauv duplex steel, vim yog kev txiav txim siab ua haujlwm ntawm cov ntsiab lus alloying, ua rau nws muaj kev xaiv txaus los ntawm ntau hom kev siv.
Daim ntawv thov ntawm Duplex Stainless Hlau:
Lub versatility ntawm duplex stainless hlau pom resonance nyob rau hauv ib tug array ntawm industries thiab domains, vim nws stellar corrosion kuj, txhim khu lub zog, thiab nqi-npaum cwj pwm. Feem ntau, kev ua haujlwm ntawm ntug dej hiav txwv thiab ze ntug dej hiav txwv, suav nrog cov roj drilling, desalination, thiab kev kho dej, sawv ua cov neeg tau txais txiaj ntsig zoo ntawm duplex steel qhov muaj txiaj ntsig. Ib yam li ntawd, nws cov nqi hluav taws xob txuas ntxiv mus rau kev ua tshuaj lom neeg, kev siv tub rog, cov cuab yeej tswj kev ua qias tuaj, thiab kev tsim kho kev tsim kho, qhia txog nws qhov kev ua tiav nyob rau hauv cov chaw ua haujlwm niaj hnub no.
