EN10216-5 1.4462 UNS S32205 Duplex Stainless Steel Seamless Pipe
EN10216-5 1.4462 UNS S32205 Duplex Stainless Steel Seamless Pipe
Product Overview
EN10216-5 1.4462 UNS S32205 seamless pipe is manufactured from duplex stainless steel and is designed for pressure equipment, chemical processing, oil and gas, and industrial piping applications.
The material combines an austenitic-ferritic duplex microstructure with chromium, nickel, and molybdenum alloy elements. UNS S32205, also known as Duplex 2205 stainless steel, is widely selected for applications requiring duplex stainless steel properties under demanding service conditions.
Manufactured according to EN10216-5 requirements, seamless pipes are produced with controlled chemical composition, mechanical properties, dimensional tolerances, and non-destructive testing procedures.
