A790 S32750 Super Duplex Steel Seamless Pipe For Power Generation

 
 
Overview
 

UNS S32750 is a stainless steel containing high chromium, high molybdenum, high nitrogen and low carbon for excellent corrosion resistance and high strength. It excels in highly chlorinated and acidic environments and is widely used in the chemical, oil and gas industries.

Heat treatment is the process of changing the organizational structure and properties of UNS S32750 through process treatments such as heating and cooling. Carbon is an important alloying element in UNS S32750 and has a great influence on the properties of UNS S32750.
 
Characteristic of A790 UNS S32750
 

• Composition: UNS S32750 is a super duplex stainless steel alloy that contains a high level of chromium, molybdenum, and nitrogen. This composition provides superior corrosion resistance and high strength.
• Corrosion Resistance: A key characteristic of UNS S32750 is its excellent resistance to corrosion in various environments, including those containing chloride ions. This makes it suitable for use in aggressive and corrosive conditions such as seawater and chemical processing.
• High Strength: UNS S32750 offers higher strength compared to standard duplex stainless steels, making it suitable for applications where both strength and corrosion resistance are essential.
• Duplex Structure: UNS S32750 is a duplex stainless steel, which means it has a two-phase microstructure consisting of austenite and ferrite. This structure contributes to its high strength and resistance to stress corrosion cracking.
• Good Weldability: A790 UNS S32750 exhibits good weldability, allowing it to be easily welded using common welding techniques without compromising its corrosion resistance properties.
• High Toughness: This material has high toughness, which is important for applications subjected to impact loads or where resistance to brittle fracture is required.
• Wide Range of Applications: A790 UNS S32750 is commonly used in industries such as oil and gas, chemical processing, marine, desalination, and pulp and paper due to its combination of strength, corrosion resistance, and durability.
