Chuck Metals, a leading manufacturer and supplier located in Singapore, Pulau Ujong, specializes in high-quality Super Duplex Steel S32750 Forgings designed to meet the rigorous demands of today’s industrial applications. Commonly referred to as Alloy 2507 or UNS S32750, these forgings are crafted to provide outstanding mechanical strength, corrosion resistance, and durability in harsh environments. They come in various forged shapes, including rings, flanges, discs, shafts, and custom components, all produced in line with ASTM A182 and other global standards. Chuck Metals’ S32750 forgings find extensive use in offshore oil & gas, chemical plants, and marine engineering.
Super Duplex Steel S32750 consists of about 24–26% Chromium, 6–8% Nickel, and 3–5% Molybdenum, along with Nitrogen, Manganese, and trace elements that boost its strength and corrosion resistance. Its dual-phase microstructure provides excellent protection against pitting, crevice corrosion, and chloride stress corrosion cracking. With a minimum yield strength of 550 MPa, a tensile strength reaching up to 795 MPa, and an elongation of 15–25%, these properties, combined with great weldability and impact strength, make S32750 forgings perfect for demanding high-pressure and corrosive environments.

Super Duplex Steel S32750 Forgings are widely utilized in offshore platforms, desalination systems, pressure vessels, heat exchangers, valves, and pumps, where resistance to chloride-rich conditions is crucial. Their high PREN (Pitting Resistance Equivalent Number) and impressive strength-to-weight ratio make them ideal for industries like oil & gas, chemical processing, marine construction, and power generation. These forgings deliver exceptional fatigue strength, thermal stability, and resistance to sulfide stress corrosion, making them suitable for subsea equipment, structural components, and high-load rotating parts. Their long service life ensures reliability in critical applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
