UNS S32750 Round Bar, also known as Super Duplex 2507, is a high-performance stainless steel bar widely used in highly corrosive environments due to its excellent mechanical strength and superior resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Riddhi Siddhi Impex is one of the leading manufacturers and suppliers of UNS S32750 Round Bars in India, offering premium-quality material engineered to withstand the toughest industrial conditions. The exceptional blend of chromium, molybdenum, and nitrogen in the alloy gives these bars their unmatched corrosion resistance, making them a perfect choice for marine, offshore, chemical, and desalination applications..
Riddhi Siddhi Impex manufactures UNS S32750 Round Bars using state-of-the-art production facilities, ensuring each bar meets stringent international standards such as ASTM A276, A479, and EN specifications. The production process involves hot forging, cold finishing, heat treatment, testing, and surface finishing to achieve accurate dimensions and excellent metallurgical properties. Each round bar is supplied with mill test certificates, confirming chemical composition and mechanical strength compliance..
As a widely trusted supplier, Riddhi Siddhi Impex provides UNS S32750 Round Bars to top industries across India. We supply these high-strength duplex round bars to major domestic cities including Mumbai, Delhi, Bengaluru (Bangalore), Hyderabad, Chennai, Kolkata, Pune, Ahmedabad, Surat, Vadodara, Rajkot, Nagpur, Indore, Bhopal, Jaipur, Kanpur, Lucknow, Agra, Varanasi, Amritsar, Chandigarh, Mysuru (Mysore), Udaipur, Jodhpur, Visakhapatnam, Coimbatore, Madurai, Kochi, Thiruvananthapuram, Mangalore, Nashik, Kolhapur, Chandrapur, Akola, Vilayat, Somnath, Dahej, Narmada, Ankleshwar, Navsari, Valsad, and Rajpipla..
The dual-phase microstructure of UNS S32750 gives it exceptionally high yield strength—almost double that of conventional austenitic stainless steels like 316 or 317L—making it ideal for applications requiring lightweight yet strong components. Industries prefer UNS S32750 Round Bars for fabrications where weight reduction, durability, and cost efficiency are major considerations. Its excellent toughness, even at low temperatures, ensures reliable performance in cryogenic systems..
In environments where chloride exposure is unavoidable—such as marine seawater systems, desalination plants, chemical tanks, offshore oil rigs, and heat exchangers—UNS S32750 Round Bars show excellent stability. The alloy’s superior PREN (Pitting Resistance Equivalent Number) of above 40 provides strong resistance against localized corrosion. This makes it a reliable material choice for industrial infrastructure in coastal and humid regions across India.
