Duplex Fasteners manufactured in India for oil gas chemical processing marine and high strength industrial applications

Sagar steel Corporation is a reputed Duplex Fasteners Manufacturer in India, who provides high quality fasteners that have high strength and are used in applications where high corrosive resistance and mechanical performance are required. Duplex fasteners are made using alloy duplex stainless steel which combines both austenitic and ferritic structures which provide greater strength and much greater resistance to stress corrosion cracking. The common types of these fasteners are used in oil and gas, offshore, marine, chemical processing, power generation and infrastructure markets.

Our worldwide B2B portal provides our customers with precision-manufactured duplex fasteners at a reasonable cost to those who are interested in quality, material consistency, and timely delivery. We have duplex bolt, nut, screw, stud, and washer in all sizes, thread form and finishes to suit the engineering and fabrication requirements of the many. All the duplex fasteners are produced under a close supervision of quality and are tested to guarantee the accurate dimensional precision, mechanical strength, and requirements of international standards.

Key Features of Duplex Fasteners

Duplex fasteners are chosen in the case of demanding service conditions because they are equally strong and corrosive resistant.

Greater mechanical strength as compared to conventional stainless steel fasteners.
Very good pitting and stress corrosion cracking resistance.
Performs well in marine and chloride environment.
Can be used in high pressure and structural applications.
Extensive service with minimal maintenance needs.

Duplex fasteners have these characteristics that render it a reliable choice in critical industrial fastening systems.

Besides duplex fasteners, we also offer Hastelloy Fasteners, Titanium Fasteners as well as Copper Fasteners and allow buyers to obtain a number of high performance fastening materials under a single quality manufacturer.
