Peb Duplex Steel Coil ua raws li ASTM A240/A240M qauv nruj me ntsis, nrog cov microstructure kwv yees li 50% austenite thiab 50% ferrite. Qhov sib npaug no ua rau nws muaj lub zog siab thiab kev tiv thaiv corrosion zoo - tensile strength ncav 620-800 MPa, siab dua 304 stainless steel, thaum nws qhov pitting resistance equivalent (PREN) yog tshaj 30, tuaj yeem tiv thaiv chloride environments xws li coastal areas los yog chemical tanks yooj yim.
Hauv kev kuaj dej hiav txwv (raws li ASTM G48), nws tsis muaj corrosion tom qab 12 lub hlis, kav ntev 5 npaug ntau dua li cov austenitic stainless steel li qub hauv qhov chaw hnyav. Nws yog qhov zoo rau cov kav dej roj thiab roj, desalination plants, thiab offshore structures qhov chaws uas kev ruaj khov nyob rau hauv siab siab tseem ceeb tshaj.
Hauv kev ua nto, peb tuaj yeem ua pickling thiab passivation. Qhov nto tom qab pickling ua raws li ASTM A380 qauv, nrog roughness Ra qis dua 1.6μm, thiab cov scale thiab oxide raug kho kom huv. Passivation treatment yuav tsim ib txheej 4-6μm protective film - qhov no tau kuaj los ntawm X-ray fluorescence, tuaj yeem nce corrosion resistance 35%.
Peb kuj tswj hwm kev slitting thiab cutting nruj: qhov dav yuam kev tswj hauv ±0.15mm, thiab straightness ntawm steel coil ib meter tsis tshaj 1mm. Yog li, thaum cov neeg siv coj mus ua khoom tiav, yuav muaj khib nyiab tsawg thiab yooj yim dua.
Peb khiav 3 lub tshuab tshwj xeeb duplex steel production lines, siv vacuum degassing technology uas ua kom hydrogen content qis dua 3ppm - qhov no nres hydrogen-induced cracking. Peb lub chaw kuaj siv optical emission spectrometers (accuracy 0.001%) los kuaj txhua pawg composition, thiab peb ua impact tests thaum kub -40°C (raws li ASTM E23) kom ntseeg tau qhov toughness.
Nrog peev xwm txhua xyoo 30000 tons, peb yog ib qho ntawm ob peb lub factories hauv Europe thiab Asia uas tuaj yeem tsim Duplex Steel Coil nrog ferrite-austenite ratios ruaj khov. Peb khaws 1000 tons nyob tas li, npog 0.5-6mm thicknesses.
Kev xaj tshaj 30 tons tau txais 6% discount loj thiab kev ua nto dawb. Peb lees tias yog tias ib lub coil tsis ua raws li ASTM A240 cov qauv mechanical los yog muaj pitting hauv 3 xyoo ntawm kev siv li qub, peb yuav hloov tag nrho thiab them cov nqi cuam tshuam los ntawm kev ncua.
