Known for its exceptional strength, resistance to corrosion, and longevity, Dhruv Metals, a renowned manufacturer and supplier of premium Super Duplex Steel Bars and Rods, is based in Hyderabad, India. High-performance Super Duplex alloys were used in the engineering of these bars and rods so they could survive harsh conditions like stress, pressure, and corrosion. Dhruv Metals provides precision-forged, premium Super Duplex bars in a range of grades and sizes to important industries like oil and gas, marine, chemical processing, and power generation. Dhruv Metals has established itself as a reputable brand in the speciality steel industry by emphasising timely delivery, consistent quality, and customer satisfaction.
Chromium (24–26%), nickel (6–8%), molybdenum (3–5%), nitrogen (~0.3%), and iron are the usual base elements of super duplex steel bars and rods, with trace amounts of manganese and silicon. Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking is exhibited by this dual-phase alloy. In terms of mechanical properties, Super Duplex bars offer good elongation (~25%), high tensile strength (≥750 MPa), and yield strength (≥550 MPa). Austenitic and ferritic phases work together to provide remarkable mechanical strength, toughness, and weldability—even in high-temperature and high-pressure settings—which makes them perfect for demanding engineering applications.

Industries that need high strength, corrosion resistance, and durability in challenging conditions frequently use super duplex steel bars and rods. Because of their resistance to corrosion caused by chloride, they are utilised in risers, manifolds, and subsea equipment in the oil and gas industry. They are used in the marine industry for fasteners, shafts, and structural elements that are exposed to seawater. They are perfect for heat exchanger components, pumps, and valves in chemical and petrochemical facilities. They are also used in the pulp and paper, power generation, and desalination industries for corrosive and high-pressure processes. Long service life and operational dependability are guaranteed by their superior mechanical qualities.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
