Product Introduction

Duplex stainless steel combines austenitic toughness with ferritic strength - yield strength is double that of 316L. Superior chloride stress corrosion resistance, ideal for seawater and chlorinated chemical environments. Centrifugal casting ensures uniform microstructure without segregation. Precise phase ratio control (50:50) after solution treatment. Widely used in offshore platforms, desalination, chemical vessels. Complete material certification and test reports provided.
