TIAB SA 2205

Duplex 2205 yog ib qho nitrogen txhim kho duplex stainless hlau uas tau tsim los tiv thaiv cov teeb meem corrosion uas tau ntsib nrog 300 series stainless hlau. "Duplex" piav qhia txog tsev neeg ntawm cov hlau tsis muaj steels uas tsis yog tag nrho austenitic, zoo li 304 stainless, los yog ferritic ntshiab, zoo li 430 stainless. Cov qauv ntawm 2205 duplex stainless hlau muaj cov pas dej austenite nyob ib puag ncig los ntawm cov theem ferrite txuas ntxiv. Nyob rau hauv cov mob annealed, 2205 muaj kwv yees li 40-50% ferrite. Feem ntau hu ua qib nees ua haujlwm, 2205 yog qib siv dav tshaj plaws hauv tsev neeg duplex ntawm stainless hlau.

Qhov kom zoo dua ntawm cov qauv duplex yog tias nws muab cov txiaj ntsig zoo ntawm ferritic alloy (kev ntxhov siab corrosion cracking tsis kam thiab siab zog) nrog cov austenitic alloy (yooj yim ntawm fabrication thiab corrosion kuj).

Kev siv 2205 Duplex stainless hlau yuav tsum raug txwv rau qhov kub thiab txias hauv qab 600 degree F. Ncua qhov siab kub raug tuaj yeem ua rau 2205 stainless hlau.

Corrosion Resistance

2205 duplex stainless hlau yog tus nqi tsim nyog rau ntau daim ntawv thov uas 300 series stainless hlau muaj kev cuam tshuam rau chloride kev ntxhov siab corrosion tawg. Kev ntxhov siab corrosion tawg tshwm sim thaum cov hlau tsis muaj steel raug kev nyuaj siab tensile, thaum nyob rau hauv kev sib cuag nrog cov tshuaj uas muaj chlorides. Kev kub siab ntxiv kuj ua rau muaj kev cuam tshuam ntawm cov hlau tsis muaj zog rau kev ntxhov siab corrosion cracking.

Kev sib xyaw ntawm chromium, molybdenum thiab nitrogen qhia qhov zoo ntawm 2205 rau chloride pitting thiab crevice corrosion. Qhov kev tiv thaiv no tseem ceeb heev rau cov kev pabcuam xws li cov chaw hauv dej hiav txwv, dej tsis huv, kev ua haujlwm bleaching, kaw lub voj kaw dej thiab qee cov ntawv thov ua zaub mov. Lub siab chromium, molybdenum thiab nitrogen cov ntsiab lus ntawm 2205 muab kev tiv thaiv corrosion zoo tshaj rau cov hlau tsis zoo, xws li, 316L thiab 317L hauv ntau qhov chaw.
