S32750 is a grade of Super Duplex stainless steel. Like all Super Duplex grades, it is a high-alloy of duplex containing 25% chromium, 4% molybdenum, and 7% nickel. This alloy combines the most desirable characteristics of both ferritic and austenitic steels. The high chromium, molybdenum, and nitrogen level and the combination of ferritic and austenitic steels endows it with excellent corrosion resistance to a wide variety of media, along with outstanding resistance to pitting and crevice corrosion in seawater and other chloride containing environments. Its Critical Pitting Temperature (CPT) exceeding 50°C gives it exceptional resistance to chloride stress corrosion cracking.
The grade offers high strength, low coefficient of thermal expansion and higher heat conductivity than austenitic steels and is suitable for working temperatures up to 300°C thanks to its duplex microstructure. UNS S32750 is also known as Alloy 32750 possesses excellent mechanical properties. With this grade often a light gauge of 2507 material can be used resulting in same design strength of a thicker nickel alloy, thus savings in weight and drastic reduction of overall cost of fabrication.
Characteristic Features of S32750
This grade offers good corrosion resistance, high strength, high resistance to chloride stress corrosion cracking and superior resistance to chloride pitting and crevice corrosion. It is ideal for applications up to 600° F. It offers a low rate of thermal expansion along with good weldability and workability. This grade has a combination of properties of austenitic and ferritic stainless steel.
