Mira Fasteners is a leading manufacturer of Super Duplex Steel Fasteners S32750 in Kuala lumpur, Malaysia. These packaging materials are known for their exceptional durability and corrosion resistance, and are ideal for complex industrial applications. Our S32750 fasteners offer excellent strength and performance, ensuring reliability in harsh environments. With a commitment to quality and customer satisfaction, Mira Fasteners offers a wide range of super duplex steel fasteners to meet the specific requirements of various industries.
Super Duplex Steel Fasteners made from UNS S32750, often referred to as 2507, are designed for tough applications where top-notch strength and outstanding corrosion resistance are a must. These fasteners are crafted from a super duplex stainless steel alloy that boasts around 25% chromium, 7% nickel, 4% molybdenum, and a touch of nitrogen. This unique blend significantly boosts their resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in environments rich in chlorides and aggressive chemicals. Thanks to their dual-phase microstructure of ferrite and austenite, they offer a remarkable mix of high mechanical strength and excellent corrosion resistance, making them perfect for critical and corrosive settings.

When it comes to mechanical properties, Super Duplex S32750 fasteners shine with a typical yield strength of 550 MPa and a tensile strength of about 800 MPa—more than double that of regular austenitic stainless steels. This impressive strength allows for smaller and lighter components in high-stress applications without compromising on performance or safety. Beyond their strength, these fasteners also excel in resisting erosion, fatigue, and stress-related failures, ensuring they maintain their integrity even under extreme temperatures and high-pressure conditions.
S32750 fasteners find their place in various industries, including offshore oil and gas, petrochemical processing, marine engineering, desalination plants, pulp and paper production, and chemical transport. They come in various forms such as bolts, nuts, washers, studs, and custom-threaded components, often used in flanged connections, pressure vessels, pipelines, and structural assemblies. Their reliability, long lifespan, and minimal maintenance needs make them a smart choice in environments where failure simply isn’t an option, especially compared to standard stainless steel options.
