S31803 duplex stainless hlau yog ib hom hlau nrog zoo corrosion kuj thiab siab zog (yield zog yog 2-3 npaug ntawm lwm yam austenitic steels). Cov hlau muaj cov chromium siab thiab molybdenum, yog li nws muaj peev xwm tiv taus pitting thiab zoo corrosion. Lub microstructure dual-theem ua kom ntseeg tau tias cov hlau muaj kev tiv thaiv siab rau kev ntxhov siab corrosion, thiab lub zog txhua yam kuj siab. S31803 duplex stainless hlau yeeb nkab yog nruab nrab-alloy duplex stainless hlau nrog zoo chloride kev nyuaj siab. Medium alloy hom-tus sawv cev qib yog UNS S31803 (22Cr-5Ni-3Mo-0.15N); S31803 duplex steel yeeb nkab yog siv nyob rau hauv peb hom duplex hlau (2205 duplex stainless hlau yeeb nkab, 2507 duplex stainless hlau yeeb nkab, S31803 duplex stainless hlau yeeb nkab, thiab S31803 duplex stainless hlau yeeb nkab).
Duplex Steel S31803 Welded Tube yog ib hom tubing ua los ntawm Duplex Steel Qib S31803. Cov khoom siv no ua ke austenite thiab ferrite microstructures, muab cov khoom tshwj xeeb. Cov yam ntxwv tseem ceeb ntawm Duplex Steel S31803 Welded Tube suav nrog kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj cov tshuaj chlorides thiab cov kua qaub. Nws kuj muaj lub zog siab, tso cai rau nws tiv taus cov kev xav tau.

Qhov zoo ntawm kev siv Duplex Steel S31803 Welded Tube dua lwm cov ntaub ntawv
Siv Duplex Steel S31803 Welded Tube muaj ntau qhov zoo dua lwm cov ntaub ntawv hauv ntau daim ntawv thov. Nws qhov tshwj xeeb corrosion kuj ua tau zoo dua cov pa stainless hlau, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav uas muaj chlorides, acids, thiab dej hiav txwv. Qhov ntawd ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov roj av thiab roj av, kev ua tshuaj lom neeg, thiab kev siv dej hiav txwv. Duplex Steel S31803 Welded Tube muaj lub zog siab, tso cai rau nws los tiv thaiv cov khoom hnyav thiab kev kub ntxhov.
