Super Duplex Stainless Steel Sheet
Super duplex stainless steel sheets are a type of stainless steel alloy that contains high levels of chromium, molybdenum, and nitrogen, making them highly resistant to corrosion, stress corrosion cracking, and pitting. Super duplex stainless steel sheets are ideal for use in harsh environments such as offshore oil rigs, chemical processing plants, and desalination plants.
At Om Steel, we offer a range of super duplex stainless steel sheet grades, including S32750 and S32760, each with its own set of mechanical properties and corrosion resistance. Our sheets are available in a range of sizes and thicknesses to meet your specific needs.
In addition to their superior corrosion resistance, super duplex stainless steel sheets also offer high strength and durability, making them ideal for use in heavy-duty applications. They also have excellent weldability, making them easy to fabricate and install.
Wide Range of Super duplex stainless steel sheets
LDX 2101® is a low-nickel alternative to standard austenitic stainless steels such as Type 304L or 316L which can save cost while maintaining good mechanical and corrosion-resistant properties.
2205® is one of the most widely used types of duplex stainless steel due to its excellent combination of strength and corrosion resistance properties.
2507® is a super duplex stainless steel that offers even higher levels of strength and corrosion resistance than 2205®, making it an excellent choice for highly corrosive environments.
Zeron® 100 is a highly alloyed super duplex stainless steel that offers excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in seawater environments.
Ferralium® 255 is a high-strength super duplex stainless steel that offers excellent resistance to chloride stress corrosion cracking and erosion-corrosion.
