Super Duplex 2507 Round Bar Supplier in Mumbai for Offshore and Corrosion Resistant Applications
When equipment is exposed to seawater, chlorides, pressure and high mechanical loads at the same time, ordinary stainless steel may not provide the required combination of performance.
This is why engineers working in offshore, marine, chemical and oil-and-gas applications often consider Super Duplex 2507.
Super Duplex 2507 is a high-alloy duplex stainless steel commonly identified by:
UNS S32750
and:
EN 1.4410
The alloy combines an austenitic-ferritic microstructure with high chromium, molybdenum and nitrogen content.
It is designed for demanding corrosion-resistant applications while providing substantially higher strength than many conventional austenitic stainless steels. Technical references identify UNS S32750 as Super Duplex 2507 and note its use in highly corrosive and chloride-heavy environments.
For companies searching for a Super Duplex 2507 Round Bar Supplier Mumbai, the material grade alone is not enough.
A proper enquiry should identify:
UNS designation + specification + diameter + length + condition + quantity + certification.

Why is Super Duplex 2507 Used?
Super Duplex 2507 is selected for applications where both strength and corrosion resistance are important.
An offshore component, for example, may experience:
seawater + chloride + pressure + mechanical loading.
A material needs to survive all of these conditions rather than just one.
The duplex structure and alloy chemistry provide a useful combination of high strength and corrosion resistance.
Technical references describe Super Duplex 2507 as a 25Cr nickel-molybdenum-nitrogen duplex stainless steel intended for highly corrosive and chloride-heavy service.
For stainless-steel and corrosion-engineering information, buyers can also consult Nickel Institute.
What is UNS S32750?
UNS S32750 is the Unified Numbering System designation for Super Duplex 2507.
Industrial buyers may therefore search:
- Super Duplex 2507
- 2507 Stainless Steel
- UNS S32750
- S32750 Round Bar
- Duplex 2507
- Super Duplex S32750
For procurement, the UNS number should be accompanied by the product specification and dimensions.
What is EN 1.4410?
The European material designation commonly associated with Super Duplex 2507 is:
EN 1.4410
This designation may appear in European drawings, specifications and purchasing documents.
A clear enquiry can therefore state:
Super Duplex 2507 / UNS S32750 / EN 1.4410
This gives the supplier several ways to identify the same base material.
Super Duplex 2507 Material Identification
Common industrial search terms include:
- Super Duplex 2507
- Super Duplex S32750
- UNS S32750
- 2507 Stainless Steel
- Duplex 2507
- EN 1.4410
- S32750 Round Bar
- Super Duplex Round Bar
The exact specification should always be confirmed before purchasing.
ASTM A276 Super Duplex 2507
ASTM A276 covers stainless steel bars and shapes within its scope.
Super Duplex 2507 Round Bar can be specified to applicable requirements of this standard.
A purchase enquiry should contain:
- Grade
- UNS designation
- ASTM specification
- Diameter
- Length
- Condition
- Quantity
- Testing
- Certification
Current standard requirements should be verified through ASTM International.
ASTM A479 Super Duplex 2507
ASTM A479 covers stainless steel bars and shapes for pressure vessels and other applications within its scope.
For pressure-related applications, the buyer should confirm whether ASTM A479 or another specific standard is required.
The engineering drawing or purchase specification should always take priority.
Super Duplex 2507 Chemical Composition
Important alloying elements include:
- Chromium
- Nickel
- Molybdenum
- Nitrogen
The grade contains substantially more chromium and molybdenum than many conventional stainless steels.
These elements contribute to its resistance to localized corrosion.
The exact chemical limits should always be checked against the applicable standard and Material Test Certificate.
Super Duplex 2507 Properties
Important Super Duplex 2507 properties include:
- High yield strength
- High tensile strength
- Strong chloride resistance
- High resistance to pitting
- Good crevice-corrosion resistance
- Useful resistance to stress-corrosion cracking
- Good mechanical performance
The exact properties depend on product form and material condition.
Super Duplex 2507 Mechanical Properties
One of the major advantages of Super Duplex 2507 is its high mechanical strength.
A typical published data sheet gives approximately 116 ksi tensile strength and 80 ksi yield strength for its listed material condition, although actual project values must be taken from the applicable specification.
High strength can be particularly useful in:
- Pressure equipment
- Offshore structures
- Shafts
- Fasteners
- Pumps
- Valves
Super Duplex 2507 Tensile Strength
Tensile strength is important when the bar is machined into components carrying substantial mechanical loads.
Applications may include:
- Shafts
- Fasteners
- Pins
- Valve components
- Pump components
The actual certified tensile strength should be verified against the purchase specification.
Super Duplex 2507 Yield Strength
High yield strength is another important reason engineers consider Super Duplex 2507.
It can help components withstand high loads without permanent deformation.
Potential applications include:
- Pressure-related components
- Offshore equipment
- Shafts
- Fasteners
- Mechanical assemblies
Super Duplex 2507 Hardness
Hardness depends on:
- Material condition
- Processing
- Heat treatment
- Cold work
- Product form
For critical applications, the required hardness should be stated in the purchase requirement.
Super Duplex 2507 Corrosion Resistance
Corrosion resistance is a major reason for choosing Super Duplex 2507.
Its high chromium, molybdenum and nitrogen content provides strong resistance to many forms of localized corrosion.
Potential service environments include:
- Seawater
- Chloride solutions
- Offshore environments
- Chemical process fluids
- Marine atmospheres
However, actual corrosion performance depends on concentration, temperature, flow, contamination and other service conditions.
Super Duplex 2507 Pitting Resistance
Pitting corrosion can create small localized cavities that penetrate deeply into metallic components.
This is particularly important in chloride-rich environments.
Super Duplex 2507 has a high pitting-resistance capability associated with its alloy chemistry.
A published technical reference reports a PREN of approximately 40–43, depending on the source and calculation basis.
PREN should be treated as an indicator rather than a complete prediction of service performance.
Super Duplex 2507 Chloride Resistance
Chlorides are particularly aggressive toward many stainless steels.
Super Duplex 2507 is designed for severe chloride-containing conditions.
Potential applications include:
- Offshore platforms
- Seawater systems
- Desalination
- Marine equipment
- Oil and gas equipment
The actual service temperature and chloride concentration remain important.
Super Duplex 2507 PREN
PREN means Pitting Resistance Equivalent Number.
It is commonly used as an indicator when discussing the pitting resistance of stainless steels.
Super Duplex 2507’s chromium, molybdenum and nitrogen contents result in a high PREN compared with many conventional stainless steels.
However, PREN should not be used as the only material-selection criterion.
