S31803 Duplex Stainless Hlau TubeNws muaj kev tiv thaiv corrosion zoo heev, siab dua qib 316. Nws tiv taus cov tshuaj tiv thaiv hauv zos xws li intergranular, crevice thiab pitting. Lub CPT ntawm cov duplex steels yog hais txog 35 degree. Gr 2205 qib resists chloride stress corrosion cracking (SCC) mus txog 150 degree. Duplex F51 Stainless Hlau yog qhov tsim nyog hloov pauv rau austenitic stainless hlau, tshwj xeeb tshaj yog nyob rau hauv qhov chaw tsis ua hauj lwm ntxov thiab ib puag ncig marine.
