EN10216-5/1.4410, EN10297-2/1.4410 Duplex and Supper Duplex Seamless Stainless Steel Pipe
Product Information:
Duplex Seamless Stainless Steel Pipes are manufactured according to industry standards such as ASTM A790 (standard specification for seamless and welded ferritic/austenitic stainless steel pipe).
Duplex Seamless Stainless Steel Pipes are favored for their combination of corrosion resistance, strength, and toughness, making them suitable for demanding applications in industries where these properties are essential. Their seamless construction ensures a smooth internal surface and structural integrity, further enhancing their performance in critical applications.
Duplex stainless steel is weldable using common welding techniques, though care must be taken to maintain the balance of alloying elements and prevent the formation of undesirable phases.
