DIN 1.4438 EFW Tube Kasedhiya Miturut Standar lan Spesifikasi Internasional
Kaya paduan 316, kimia baja tahan karat karbon rendah ngandhut kromium, nikel, lan molibdenum.Paduan austenitik sing kagolong ing seri 300, 317L Stainless Steel Seamless Tubes dianggep minangka modifikasi saka kelas 316. Isi molibdenum ing kimia campuran iki luwih dhuwur tinimbang 3%.Campuran bahan molybdenum sing diowahi iki nduweni sawetara ciri penting.Contone, WERKSTOFF NR.1.4438 Heat exchanger Tube nuduhake resistensi sing luwih gedhe kanggo korosi pitting lan crevice dibandhingake karo alloy 316.
