Super duplex stainless steel sheets and plates
Super duplex stainless steel sheets and plates are designed for environments that demand exceptional strength, durability, and corrosion resistance. With higher levels of chromium, molybdenum, and nitrogen, super duplex stainless steel is engineered for applications exposed to severe conditions, such as oil and gas extraction, marine engineering, and chemical processing.
Key Benefits of Super Duplex Stainless Steel Sheets and Plates
- Outstanding Corrosion Resistance: Super duplex stainless steel offers excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking, making it ideal for marine and industrial applications.
- High Strength: With nearly double the yield strength of austenitic stainless steels, super duplex plates and sheets are suitable for high-stress applications.
- Enhanced Fatigue and Abrasion Resistance: Super duplex materials offer superior fatigue strength and resistance to abrasion, essential for heavy-duty industrial environments.
- Long Service Life: Due to their durability and corrosion resistance, super duplex stainless steel sheets and plates reduce maintenance needs, leading to a longer service life.
- Cost-Effective Solution: With increased durability and minimal maintenance, super duplex grades provide long-term cost savings.
Grades for Super Duplex Stainless Steel Sheets and Plates
- Super Duplex 2507 (UNS S32750): Known for exceptional resistance to pitting, chloride stress corrosion, and high strength, 2507 is suitable for offshore and highly corrosive applications.
- Super Duplex 32760 (UNS S32760): With added tungsten and copper, 32760 provides even greater corrosion resistance, ideal for subsea, chemical processing, and petrochemical industries.
- Other Grades: Additional super duplex grades, such as S32707, offer tailored performance attributes for specific applications.
Applications of Super Duplex Stainless Steel Sheets and Plates
- Oil and Gas Industry: Super duplex plates and sheets are used in pipelines, heat exchangers, and pressure vessels in offshore oil rigs, where exposure to seawater and corrosive gases demands high durability.
- Chemical Processing: Suitable for tanks, reactors, and equipment exposed to aggressive chemicals, super duplex stainless steel is resistant to acidic environments.
- Marine Engineering: Super duplex materials are highly resistant to seawater corrosion, making them ideal for desalination plants, seawater cooling systems, and shipbuilding.
- Pulp and Paper Industry: Super duplex stainless steel resists the chloride-laden and acidic environments found in pulp and paper manufacturing.
- Power Generation: Used in nuclear and conventional power plants for components that require high strength and corrosion resistance.
