32750 / F53

Super Duplex 32750 is a high-performance stainless steel grade with improved corrosion resistance and strength compared to regular duplex stainless steel. It has a high nickel, chromium, and molybdenum content. Suitable for demanding applications.

Super Duplex 32750 is a type of high-performance stainless steel that is known for its excellent combination of strength, corrosion resistance, and durability. This grade is a type of super duplex stainless steel, which means that it has a higher nickel, chromium, and molybdenum content compared to regular duplex stainless steel. These elements provide improved corrosion resistance and strength to the material.

Super Duplex 32750 has a dual-phase microstructure that consists of both austenitic and ferritic phases. The high nickel content provides the material with excellent resistance to both stress corrosion cracking and pitting corrosion, while the high molybdenum content provides improved resistance to crevice corrosion. The high chromium content provides excellent resistance to oxidizing environments and corrosion resistance in general.

In terms of mechanical properties, Super Duplex 32750 has high tensile strength, yield strength, and impact resistance, making it suitable for a wide range of demanding applications. Some of these applications include offshore oil and gas platforms, chemical processing equipment, heat exchangers, and pressure vessels.

It's important to note that the properties of Super Duplex 32750 can vary based on the specific manufacturer and production process. It is always recommended to consult with the manufacturer's specifications for the specific material you are using for an accurate list of properties and guidelines for use.
