ASTM A240 UNS S32750 Super Duplex Stainless Steel Strip
ASTM A240 UNS S32750 Super Duplex Stainless Steel Strip Quick Details
ASTM A240 UNS S32750 super duplex stainless steel strip, also known as 2507 duplex stainless steel strip. It is also called EN 1.4410 strip. It is a very popular stainless steel strip allow in the market.
High molybdenum, chromium and nitrogen content in UNS S32750 super duplex stainless steel help this strip material withstand pitting and crevice corrosion.
Grade 2507 strip material is also resistant to chloride stress corrosion cracking, to erosion corrosion, to corrosion fatigue, to general corrosion in acids. UNS S32750 super duplex stainless steel strip has good weldability and very high mechanical strength.
At HZW, Our team can help provide round edge 2507 super duplex strips to meet your special demands.

ASTM A240 UNS S32750 Super Duplex Stainless Steel Strip: The Ultimate Guide
When you choose to buy quality UNS S32750 super duplex stainless steel strip, there have some important points we need to know before we get started.
What are ASTM A240 UNS S32750 super duplex stainless steel strips?
Our high quality UNS S32750 super duplex stainless steel strip composed of 25% chromium, 4% molybdenum and 7% nickel alloy.
Super duplex 2507 stainless steel strip is a ferritic-austenitic stainless steel strip, which combines the most beneficial properties of many ferritic stainless steel strip(430 stainless steel strip) and austenitic stainless steel strip(such as 304L stainless steel strip, 310S stainless steel strip, 321 stainless steel strip, 347 stainless steel strip).
Because the 2507 stainless steel strip contains high contents of chromium and molybdenum, so it has extremely good resistance to pitting, crevice corrosion and uniform corrosion.
The dual-phase microstructure ensures that the 2507 stainless steel strip has a high resistance to stress corrosion cracking, and the mechanical strength of it is also high.
ASTM A240 UNS S32750 super duplex stainless steel strip application
Due to excellent resistance to pitting, crevice corrosion and uniform corrosion, quality grade UNS S32750 super duplex stainless steel strip is widely used for below applications.
- Oil and gas industry
- Offshore oil platform (heat exchanger tube, water treatment and water supply system)
- Petrochemical equipment
- Desalination equipment
- Mechanical and structural components
- Combustion gas purification equipment
What are ASTM A240 UNS S32750 super duplex stainless steel strips edges?
Mill edge is a non-trimmed edge appearance after hot or cold rolling and annealing/pickling process. It usually leaved an irregular pinhole line on the edge side around 10mm to 15mm.
Slit/slitting edge means we will trim irregular pinhole line on our slitting machine.
In addition, our expert team can also provide round edge 2507 strips to meet your project needs.
UNS S32750 Super Duplex Stainless Steel Strip Vs. UNS S32205 Stainless Steel Strip
The standard of duplex stainless steel 2205 is ASTM A240.
Duplex stainless steel 2205 alloy is a duplex stainless steel composed of 22% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy.
It has high strength, good impact toughness and good overall and local stress corrosion resistance.
2507 (UNS S32750) super duplex stainless steel is composed of 25% chromium, 4% molybdenum and 7% nickel.
It has strong strength and corrosion resistance, and is mainly used in chemical processing, petrochemical and sea equipment.
It has strong resistance to chloride corrosion, high thermal conductivity and low thermal expansion coefficient.
The high content of chromium, molybdenum and nitrogen makes it highly resistant to pitting corrosion, crevice corrosion and uniform corrosion.
The 2205 and 2507 stainless steel strip has become an important engineering material during past decades. Do you know what is the difference between two stainless steel strips?
