Duplex Stainless Hlau 2205 muaj lub cev-centered cubic ferrite thiab lub ntsej muag-centered cubic austenite. Qhov ntim piv ntawm ob theem yog li 1: 1. Nws ua ke cov kev ua haujlwm tsis zoo ntawm austenitic stainless hlau thiab cov kev ntxhov siab corrosion ntawm ferritic stainless hlau, uas ua rau nws siv dav hauv cov cheeb tsam corrosive thiab lub sijhawm muaj zog siab.

Tsis tas li ntawd, SS 2205 kuj muaj lub zog zoo thiab tawv, thiab tuaj yeem ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias ib puag ncig. Nws yog dav siv nyob rau hauv kev lag luam tshuaj, roj av, natural gas, marine engineering, tshuaj thiab lwm yam kev lag luam, thiab tshwj xeeb tshaj yog haum rau cov khoom siv thiab cov kav dej hauv marine ib puag ncig.

Nws tuaj yeem tiv taus qhov yaig ntawm corrosive media xws li dej hiav txwv, tshuaj tsuag ntsev, kua qaub thiab alkali, thiab tseem tuaj yeem tiv taus qhov chaw ua haujlwm nyob rau hauv huab cua xws li kev kub siab thiab kub. Qhov kev ua tau zoo ntawm stainless hlau 2205 yog vim nws lub koom haum tshwj xeeb. Lub koom haum no ua rau SS 2205 muaj ob qho tib si lub zog thiab corrosion kuj ntawm austenitic stainless hlau thiab lub toughness thiab yooj yim ntawm kev ua ntawm ferritic stainless hlau, yog li nws yog nrov heev nyob rau hauv industrial teb.

2205 Duplex Stainless Hlau yog ib qho kev txuag nyiaj, kev ua haujlwm siab stainless hlau, thiab nws kuj yog cov khoom siv high-tech, cov khoom muaj nqis ntxiv. Nws muaj cov zis loj thiab ntau yam kev siv. Vim tias nws muaj ob qhov zoo ntawm austenitic thiab ferritic stainless hlau, nws tau siv dav hauv cov roj thiab roj mining, npaj nkoj, flue gas desulfurization, seawater desalination thiab lwm yam lag luam.

2205 duplex steel yeeb nkab ua ke nrog cov khoom muaj txiaj ntsig zoo tshaj plaws ntawm ferrite thiab austenite thiab muaj kev tiv thaiv zoo rau chloride ion kev ntxhov siab corrosion tawg. Nws yog tsim los ntawm 21% chromium, 2.9% molybdenum thiab 4.5% nickel-nitrogen alloy. Lub zog tawm los yog ob zaug ntawm austenitic stainless hlau. Cov yam ntxwv no ua rau nws hnyav, muab cov khoom no kom zoo dua 316 thiab 317L. Vim nws cov ntsiab lus chromium thiab molybdenum siab, cov hlau no muaj kev tiv thaiv zoo rau pitting thiab zoo corrosion. Lub dual-theem microstructure xyuas kom meej tias cov hlau muaj lub zog txhua yam thiab zoo heev tiv thaiv kev ntxhov siab corrosion tawg.

Thaum lub sij hawm vuam txheej txheem, kev saib xyuas yuav tsum tau them nyiaj rau kev xaiv cov txheej txheem vuam thiab muab tub lim kom zoo thiab tiv thaiv corrosion ntawm cov pob qij txha. Feem ntau siv txoj kev vuam muaj xws li arc vuam, roj shielded vuam thiab laser vuam. Tsim nyog welding preheating thiab tom qab kev kho cua sov tuaj yeem txhim kho kev ua haujlwm ntawm cov pob qij txha.

Nyob rau hauv niaj hnub engineering, kev kho deg ntawm cov ntaub ntawv tseem ceeb heev los txhim kho lawv cov corrosion kuj, zoo nkauj thiab txhua yam khoom. SS 2205, raws li ib tug duplex stainless hlau, tsis tsuas yog nws ua tau zoo nyob rau hauv cov nqe lus ntawm nws cov yam ntxwv yooj yim, tab sis nws cov txheej txheem kev kho deg yog txawm ntau eye-catching, ua rau nws nrov nyob rau hauv ntau yam teb.

Ua ntej tshaj plaws, kev kho saum npoo ntawm SS 2205 tuaj yeem txhim kho nws cov corrosion kuj zoo. Los ntawm kev siv lub cev thiab tshuaj txoj kev xws li pickling thiab tua peening, oxides, roj stains thiab lwm yam impurities nyob rau saum npoo ntawm cov khoom yuav raug tshem tawm. Yog li ntawd, lub smoothness ntawm cov khoom yuav nce, thiab ib tug ntom oxide zaj duab xis yuav tsim. Txoj kev kho no tsis tsuas yog txo qhov tshwm sim ntawm corrosion, tab sis kuj txhim kho kev ruaj ntseg ntawm stainless hlau, ua rau nws haum rau corrosive ib puag ncig xws li marine engineering thiab chemical khoom.

Qhov thib ob, kev kho polishing ntawm SS 2205 ua rau nws nto smoother thiab ci dua. Los ntawm kev ua haujlwm polishing lossis tshuaj polishing txheej txheem, tus nqi ntawm qhov roughness tuaj yeem txo tau zoo, thiab glossiness tuaj yeem txhim kho, ua rau cov hlau tsis muaj hlau yooj yim dua los ntxuav thiab tswj, thaum ua kom nws zoo nkauj. Qhov no muaj qhov tseem ceeb ntawm daim ntawv thov rau qee cov khoom siv thiab cov khoom siv hauv tsev uas xav tau qhov ci ci.

Nyob rau hauv cov ntaub ntawv siv tau, qhov saum npoo ntawm SS 2205 kuj tuaj yeem kho tau los ntawm kev txau, plating, thiab lwm yam. Piv txwv li, txau txheej txheej ntawm cov xim pleev xim tuaj yeem tsim cov txheej tiv thaiv kom muaj kev tiv thaiv corrosion ntawm cov khoom siv no thiab txuas ntxiv nws lub neej kev pab cuam. Hlau txheej tuaj yeem tsis tsuas yog nce hardness ntawm stainless hlau, tab sis kuj txhim kho nws cov hnav tsis kam, uas yog haum rau qee qhov chaw uas yuav tsum tau muaj zog saum npoo.

Tsis tas li ntawd, cov txheej txheem los tiv thaiv tus ntiv tes ntawm SS 2205 kuj tau nyiam ntau yam. Los ntawm kev siv txheej txheem txheej txheej tshwj xeeb, cov hlau tsis muaj steel hlau tuaj yeem tiv taus cov ntiv tes, stains thiab lwm yam kuab paug, ua kom yooj yim rau kev ntxuav thiab khaws cia, thaum tswj kev zoo nkauj ntawm qhov chaw.

Zuag qhia tag nrho, 2205 duplex stainless hlau txuas ntxiv tsim kho tshiab hauv kev kho tshuab saum npoo av, muab ntau txoj hauv kev rau nws daim ntawv thov hauv ntau qhov kev lag luam. Txawm hais tias nyob rau hauv marine engineering, architectural kho kom zoo nkauj, cov khoom siv tshuaj lom neeg lossis cov khoom siv hauv tsev, cov txheej txheem kho saum npoo ntawm SS 2205 tuaj yeem ua tau raws li qhov xav tau ntawm cov xwm txheej sib txawv, ua rau nws ua tus thawj coj hauv kev xaiv cov khoom siv. Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, nws ntseeg tau tias SS 2205 yuav ua rau muaj kev hloov pauv ntau dua hauv kev kho cov thev naus laus zis, muab ntau txoj hauv kev rau ntau yam kev thov.
