Duplex S31803 Pipa tanpa jahitan
Tabung ASTM A789 UNS S31803 mengacu pada tabung tanpa jahitan dan las yang diproduksi sesuai dengan ASTM A789/ASTM A1789M, yang mengandung sekitar 50% ferrit dan 50% austenit.Ketahanan korosi tegangan ASTM A789 dalam larutan klorida netral dan H2S lebih baik daripada 304L, 316L austenit stainless steel, dan 18-5mo tipe duplex stainless steel.sangat cocok untuk kisaran suhu -50°F/+600°F.juga dipertimbangkan untuk aplikasi di luar kisaran suhu ini, tetapi ada beberapa keterbatasan, terutama ketika diterapkan pada struktur las.
