Rupal Metals, a prominent manufacturer and supplier in Delhi, India, is well known for supplying high-quality Super Duplex Steel Square Bars to industries in all spheres. With uncompromising dedication to precision, durability, and global standards, Rupal Metals ensures each square bar satisfies the rigorous demands of the engineering and industrial sectors. Their cutting–edge manufacturing units and seasoned team ensure high-performance products designed specifically for strength and corrosion resistance. Rupal Metals is relied upon for guaranteed deliveries, reasonable prices, and large inventory, thus becoming the first choice among customers looking for premium-grade Super Duplex Steel Square Bars in India.
Super Duplex Steel Square Bars consist of major constituents chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen (0.2–0.3%), accompanied by minor contents of manganese, silicon, and carbon. The alloy possesses superior resistance to pitting, crevice corrosion, as well as chloride stress corrosion cracking. Mechanically, these bars offer high tensile strength of about 750 MPa, yield strength of approximately 550 MPa, and elongation of approximately 25%. Their dual-phase microstructure makes them superior in terms of toughness and hardness, making them perfect for application in aggressive and high-pressure conditions where strength and corrosion protection are both required.

To maintain Super Duplex Steel Square Bars, clean them regularly to remove contaminants, avoid exposure to extreme temperatures for prolonged periods, and inspect for signs of corrosion or damage in harsh environments.
Yes, Super Duplex Steel Square Bars can be welded using techniques like TIG or MIG welding. Proper preheating and post-weld heat treatment are essential to maintain their corrosion resistance and mechanical properties.
Yes, Super Duplex Steel Square Bars are suitable for natural gas applications due to their excellent resistance to corrosion, high strength, and ability to withstand harsh environments commonly found in the natural gas industry.
Super Duplex Steel Square Bars are used very extensively in oil and gas, chemical processing, marine engineering, and desalination industries. These bars are best for structural uses in offshore platforms, pressure vessels, subsea piping, and shipbuilding because of their superior corrosion resistance and high mechanical strength. They are also employed for use in heat exchangers, pulp and paper equipment, and components subject to aggressive and corrosive environments. Their performance, long life, and resistance to harsh conditions make them a critical material in industries requiring performance as well as durability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
