Product Introduction

Compared with ferritic stainless steel and austenitic stainless steel, the Stainless Steel Duplex Pipes 2507 have good welding performance. They are neither like ferritic stainless steel in the welding heat affected zone, due to the severe grain coarsening and plastic toughness greatly reduced, nor like austenitic stainless steel, more sensitive to welding heat crack. Because of its special advantages, these Stainless Steel Duplex Pipes are widely used in petrochemical equipment, seawater and wastewater treatment equipment, oil and gas pipelines, paper machinery and other industrial fields.


Characteristics

●High resistance to chloride stress corrosion cracking

●High Strength

●Superior resistance to chloride pitting and crevice corrosion

●Good general corrosion resistance

●Suggested for applications up to 600° F

●Low rate of thermal expansion

●Combination of properties given by the austenitic and ferritic structure

●Good weldability and workability
