Super Duplex S32750 Sheet Plate

If you’re in the high-performance sheets and plate market, you may have come across Super Duplex S32750. A critical component of many industrial and architectural applications, the Super Duplex S32750 sheet plate possesses excellent corrosion resistance in harsh environments, robust mechanical properties, and an impressive array of potential uses. In this blog post, we’ll delve into the physical and mechanical properties of Super Duplex S32750 sheet plate and explore its use cases, heat treatment options and overall corrosion resistance.

What is Super Duplex S32750 Sheet Plate?

Super Duplex Steel S32750 Plates is a high-strength stainless steel plate characterized by its resistance to corrosion, exceptional strength, and outstanding formability. It also offers great weldability and heat resistance properties for improved durability and longevity. This sheet plate works great in severe environments due to its superior tensile strength, which can be twice as much as traditional grades of stainless steel.

Super Duplex S32750 sheet plate Composition

Super Duplex 2507 Sheet  combines austenitic and ferritic stainless steel. As a “duplex” metal, it contains a mixture of nickel, chromium, and molybdenum in varying percentages, adding resistance to stress corrosion cracking, pitting, and crevice corrosion. Additionally, its nickel content contributes to improved toughness and impact strength, providing further benefits to a broad range of end-use scenarios.
