Super Duplex Steel S32750 is a high-performance, corrosion-resistant alloy that finds widespread use in various industries, particularly in applications where resistance to both general and localized corrosion is crucial. Flanges made from Super Duplex Steel S32750 Flanges are highly sought after for their excellent mechanical properties and resistance to harsh environments.
Chemical Composition: Super Duplex Steel S32750 is a duplex stainless steel with a dual-phase microstructure consisting of both austenitic (ferritic) and ferritic phases. The chemical composition includes a high percentage of chromium, molybdenum, and nitrogen, contributing to its superior corrosion resistance. The addition of elements like nickel and copper further enhances its overall performance.
Corrosion Resistance: One of the standout features of Super Duplex Steel S32750 is its exceptional corrosion resistance. It exhibits resistance to a wide range of corrosive environments, including those containing chlorides and sulfides. This makes it an ideal choice for applications in chemical processing, oil and gas, and marine industries where exposure to aggressive media is common.
Table Of Content
Mechanical Properties: Super Duplex Steel S32750 flanges offer excellent mechanical properties, including high tensile strength and impact toughness. These properties make them suitable for use in high-pressure and high-temperature applications, such as in piping systems and pressure vessels.
