Super Duplex Steel S32760

Description

Super Duplex Steel 32760 / UNS S32760 / Alloy 1.4510 / F55

Alloy 32760 is a super duplex stainless steel supplied in the solution annealed condition. Super duplex 32760 combines the desirable aspects of both austenitic and ferritic grades. The higher chromium, molybdenum and nitrogen contents result in a Pitting Resistance Equivalent number (PREN) of >40, providing pitting and crevice corrosion resistance superior to austenitic and duplex stainless steels in almost all corrosive media, and a Critical Pitting Temperature exceeding 50°C.

Super duplex 32760 features

Superior Corrosion Resistance

With a Pitting Resistance Equivalent number (PREN) of >40, duplex 32760 provides unparalleled resistance to pitting and crevice corrosion in chloride-containing environments.

Critical Pitting Temperature exceeds 50°C, making it ideal for applications involving seawater and other corrosive media.

High Mechanical Strength

Super duplex 32760 offers higher strength compared to both austenitic and 22% Cr duplex stainless steels, making it suitable for high-pressure and high-stress applications.

Excellent Impact Strength

This alloy exhibits outstanding ductility and impact strength at both ambient and sub-zero temperatures, ensuring reliability even in harsh conditions.

Resistance to Stress Corrosion Cracking

UNS 32760 demonstrates exceptional resistance to chloride-induced stress corrosion cracking, a common issue with traditional stainless steels.

Weldability and Machinability

Suitable for various welding methods, including shielded metal arc welding, TIG welding, and plasma welding. Preheating and post-heating are not required, simplifying the fabrication process.
