Super Duplex S32760 Sheet Plate

If you’re in the market for robust material resistant to corrosion and exceptional strength, Super Duplex Steel UNS S32760 Sheets & Plates is an excellent option. It’s a popular choice for a broad range of applications requiring high yield strength and excellent resistance to stress corrosion cracking, pitting, and corrosion fatigue. In this blog post, we’ll explore the physical and mechanical properties, composition, and heat treatment of the UNS S32760 Sheets & Plates. We’ll also discuss its various uses and its impressive corrosion resistance properties.

What is Super Duplex S32760 Sheet Plate?

S32760 Super Duplex Steel Sheet Plate is a high-grade stainless steel alloy with excellent strength and corrosion resistance properties. S32760 Super Duplex Steel Plates performs excellently in tough environmental conditions, such as in the marine environment or heavy industrial areas. The UNS S32760 alloy is also highly resistant to stress corrosion cracking and crevice corrosion and has excellent welding characteristics. It offers superior resistance to pitting and chloride active acids compared to other ferritic super-austenitic alloys.

UNS S32760 Sheets Plate Composition:

Super Duplex Steel S32760 Industrial Sheet comprises approximately 25% chromium, 7% nickel, and a small amount of tungsten, nitrogen, manganese, and molybdenum. Unlike regular duplex stainless steel, S32760 Sheets & Plates has twice the yield strength and corrosion resistance thanks to its balanced composition. The tungsten presence helps its mechanical properties, while the nitrogen contributes to its corrosion resistance properties.
