Grades & standards
- ASTM A240
Source Super Duplex Plates, Sheets & Coils from verified mills, manufacturers and stockists on MetalMitra. Options span coils, foils and rolls, produced to ASTM A240, and every order can ship with an EN 10204 3.1 certificate.
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.
What you can source
- Hot Rolled Plates — Heavier thickness plates for structural and pressure work.
- Cold Rolled Sheets — Thin sheets with smooth surface finish.
- Coils & Strips — Coils and slit strips for continuous processing.
- Circles & Cut Shapes — Blanks, circles, rings and profile-cut pieces.
Key properties
- 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.
