Super Duplex Steel Fasteners Manufacturer in India

Sawariya Metal Industries is a manufacturer, supplier, stockist and exporter of Super Duplex Steel Fasteners in different sizes, grades, specifications and finishes for industrial and engineering applications.

Super Duplex Steel Fasteners are mechanical joining components such as bolts, nuts, studs, screws and washers used to assemble flanges, structures, machinery and 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 Steel Fasteners 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 Steel Fasteners

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.
