Super Duplex Stainless Steel Sheets

Super Duplex Stainless Steel Sheets

Super duplex stainless steel sheets represent a remarkable category of stainless steel alloys distinguished by their elevated levels of chromium, molybdenum, and nitrogen. These alloy components combine to impart outstanding resistance to corrosion, stress corrosion cracking, and pitting, rendering super duplex stainless steel sheets exceptionally well-suited for deployment in harsh and challenging environments. Key applications include offshore oil rigs, chemical processing plants, and desalination facilities.

Ashapura Steel is proud to offer a comprehensive selection of super duplex stainless steel sheet grades, including S32750 and S32760, each characterized by its unique mechanical properties and corrosion resistance attributes. Ashapura’s sheets come in a range of sizes and thicknesses, ensuring compatibility with your specific project requirements.

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.

FAQ

1)What is the difference between super duplex and 316 stainless steel?

Super duplex stainless steel and 316 stainless steel are both corrosion-resistant materials, but they differ significantly in terms of composition, corrosion resistance, strength, and application.both super duplex and 316 stainless steel offer corrosion resistance, super duplex stainless steel is better suited for more demanding applications in highly corrosive environments due to its higher alloy content and strength. The choice between the two depends on the specific requirements of the project or application.

2)Who is the manufacturer of super duplex stainless steel in Maharashtra?

There are several manufacturers and suppliers of super duplex stainless steel in Maharashtra, India. However,Ashapura provide the best the availability of specific grades and products like stainless steel,carbon steel,super duplex stainless steel.

3)What is super duplex stainless steel?

Super duplex stainless steel is a type of stainless steel that belongs to the duplex family of alloys. It is called “super” duplex because it has even higher alloy content and better corrosion resistance compared to standard duplex stainless steels. Super duplex stainless steel is known for its exceptional combination of corrosion resistance, mechanical strength, and durability, making it suitable for use in demanding and aggressive environments.
