Product Introduction

S32205 Duplex Stainless Steel Tube is a combination of austenitic and ferritic stainless steel. Duplex 2205 is often used in applications where high strength and corrosion resistance are required. Duplex 2205 pipe alloy has excellent resistance to seawater and most concentrations of sulfuric acid. In addition, 1.4462 stainless steel also exhibits good resistance to localized corrosion, including pitting, intergranular corrosion, and crevice corrosion in high temperature environments. We are a 2205 supplier with 15+ export experience. Contact us for more information and free quotes!
