Super Duplex Plates, Sheets & Coils Manufacturer in India
Sawariya Metal Industries is a manufacturer, supplier, stockist and exporter of Super Duplex Plates, Sheets & Coils in different sizes, grades, specifications and finishes for industrial and engineering applications.
Super Duplex Plates, Sheets & Coils are flat-rolled products supplied as hot-rolled plates, cold-rolled sheets, coils, strips and cut shapes for fabrication, pressure vessels and process equipment.
Super duplex stainless steel combines a balanced austenitic-ferritic microstructure with high chromium, molybdenum and nitrogen content, giving very high strength and excellent resistance to pitting, crevice corrosion and chloride stress corrosion cracking.
Typical applications for Super Duplex Plates, Sheets & Coils include offshore oil & gas, seawater systems, desalination plants, chemical processing, petrochemical, pulp & paper, marine engineering, heat exchangers and general engineering.
Key Features of Super Duplex Plates, Sheets & Coils
High Strength
Roughly twice the yield strength of standard austenitic stainless steels.
Chloride Resistance
Excellent resistance to pitting and crevice corrosion in seawater and brine.
Stress Corrosion Resistance
Strong resistance to chloride stress corrosion cracking.
Weight Saving
Higher strength allows lighter designs in suitable applications.
