1. What Is UNS S32750?

UNS S32750 is the Unified Numbering System designation for Super Duplex 2507, a high-alloy duplex stainless steel developed for demanding applications requiring high strength and corrosion resistance.

The material is also identified by the European material number EN 1.4410 and designation X2CrNiMoN25-7-4. It contains chromium, nickel, molybdenum and nitrogen, which contribute to its performance in suitable aggressive environments.

Super Duplex 2507 is used in selected oil and gas equipment, seawater systems, desalination plants, chemical processing equipment and other industrial applications.

When purchasing this grade, confirming the designation alone is not enough. The correct UNS S32750 specification must also match the product form, manufacturing route, dimensions and intended service.

2. UNS S32750 Specifications by Product Form

Different product forms may be covered by different ASTM or EN standards. The following table provides a starting point for industrial procurement.

Product formRelevant specificationGeneral scope
Round bars and other barsASTM A479 / ASME SA-479Stainless steel bars and shapes for applicable boiler and pressure-vessel uses
General stainless steel bars and shapesASTM A276 / ASME SA-276Stainless steel bars and shapes, subject to grade and product requirements
Plates, sheets and stripsASTM A240 / ASME SA-240Chromium and chromium-nickel stainless steel plate, sheet and strip
Forged flanges and componentsASTM A182 / ASME SA-182Forged or rolled alloy and stainless steel piping components
Seamless and welded pipesASTM A790 / ASME SA-790Duplex stainless steel pipe
Seamless and welded tubesASTM A789 / ASME SA-789Duplex stainless steel tubing
Butt-welding fittingsASTM A815 / ASME SA-815Wrought ferritic, ferritic/austenitic and martensitic stainless steel piping fittings
European bar productsEN 10088-3Stainless steel semi-finished products, bars, rods, wire and sections within the standard’s scope
European plate and sheet productsEN 10088-2Stainless steel sheet, plate and strip within the standard’s scope

These are relevant standards to check, not a guarantee that every listed standard is automatically applicable to every Super Duplex 2507 product. Verify the grade’s inclusion, product dimensions, delivery condition and required edition against the actual purchase specification.

3. ASTM A479 for Super Duplex 2507 Round Bars

Buyers sourcing Super Duplex 2507 round bars should verify whether ASTM A479 / ASME SA-479 is the required product specification.

ASTM A479 covers stainless steel bars and shapes for applicable boiler and pressure-vessel uses. It is relevant to industrial procurement where the project specification calls for this standard and the specified grade.

Before ordering UNS S32750 round bars, confirm:

  • Required grade: UNS S32750 / Super Duplex 2507
  • Applicable specification: ASTM A479 / ASME SA-479, where required
  • Diameter and length
  • Dimensional tolerances
  • Required delivery and heat-treatment condition
  • Mechanical testing and chemical analysis requirements
  • Material test certificate requirements
  • Quantity and delivery location

ASTM A276 may also be relevant for bar products, depending on the intended application and purchase specification. Do not substitute one standard for another without approval from the purchaser or design authority.

For exact scope information, consult the ASTM A479 standard page and confirm the current edition and applicable grade requirements before placing an order.

4. ASTM A240 for Super Duplex 2507 Plates and Sheets

When purchasing Super Duplex 2507 plates, sheets or strips, ASTM A240 / ASME SA-240 is a product specification to check.

This standard covers specified chromium and chromium-nickel stainless steel plate, sheet and strip. Buyers must confirm that UNS S32750 is covered by the required edition and that the material meets the project’s additional requirements.

A complete plate or sheet enquiry should include:

  • Grade and material designation
  • Required standard and edition
  • Thickness, width and length
  • Required surface finish
  • Quantity and cutting requirements
  • Mechanical and chemical testing requirements
  • Material certificate and inspection requirements

For pressure equipment or fabricated process systems, the design code may impose additional requirements beyond the base material specification.

Important: Do not use ASTM A240 as the specification for round bars or forged flanges. Product-form standards serve different purposes.

5. ASTM A182 F53 for Forged Components

ASTM A182 Grade F53 is an important designation associated with Super Duplex 2507 for applicable forged or rolled piping components.

It may be specified for products such as forged flanges and certain fittings or other piping components, provided the product meets the applicable standard and ordering requirements.

A procurement enquiry should identify:

  1. Required grade: ASTM A182 Grade F53 / UNS S32750, as applicable.
  2. Component type: flange, forging or other covered component.
  3. Dimensional standard and pressure class, where applicable.
  4. Required dimensions, facing, bore and connection details.
  5. Applicable design code and service requirements.
  6. Inspection, testing and material certification requirements.

A182 F53 is not a universal substitute for every Super Duplex 2507 product specification. A round bar, plate, pipe and forged flange may all use the same underlying grade designation but require different product standards.

Refer to the manufacturer’s SAF 2507 billet datasheet, which identifies UNS S32750 and EN 1.4410 and references further production according to ASTM A182 Grade F53.

6. Other Relevant Super Duplex 2507 Standards

Depending on the product, additional specifications may be relevant.

ASTM A790 for pipes

ASTM A790 is relevant to duplex stainless steel pipe, including applicable seamless and welded pipe requirements. Verify the grade, dimensions, manufacturing route and project requirements.

ASTM A789 for tubes

ASTM A789 covers duplex stainless steel tubing. It should be considered where the requirement is for tubing rather than bar or plate.

ASTM A815 for fittings

ASTM A815 covers specified wrought stainless steel piping fittings, including ferritic/austenitic grades within its scope. Check the applicable grade and component requirements.

EN 1.4410 and X2CrNiMoN25-7-4

These European designations help identify the Super Duplex 2507 grade in material documentation and supplier enquiries. They do not, by themselves, replace a required product standard.

For this reason, purchase orders should state both the material designation and the applicable product specification wherever required.

7. Material Test Certificates and Inspection

For industrial projects, documentation can be as important as the material designation itself.

Buyers should specify the required documentation before placing an order.

A material test certificate may record:

  • Material grade and applicable specification
  • Heat or cast number
  • Chemical analysis
  • Mechanical test results
  • Heat-treatment condition, where applicable
  • Product dimensions and traceability
  • Inspection and testing details

Where required by the purchase order, an EN 10204 Type 3.1 inspection certificate provides material-specific inspection results validated by the manufacturer’s authorized inspection representative independent of the manufacturing department, as defined by the applicable standard.

Do not assume every supplier or every available product automatically includes a particular certificate. Confirm documentation, traceability and inspection requirements in writing.

8. How to Order the Correct UNS S32750 Material

For procurement teams, engineers and industrial buyers, the following checklist can make an enquiry more precise.

Before requesting a quotation, provide:

  1. Material designation: Super Duplex 2507, UNS S32750, or EN 1.4410 as required.
  2. Product form: Round bar, plate, sheet, pipe, tube, flange, fitting or forging.
  3. Product standard: ASTM A479, A240, A182 F53, A790, A789 or another applicable specification.
  4. Dimensions: Diameter, thickness, length, bore, pressure class or other component dimensions.
  5. Quantity: Required pieces, lengths, weight or total quantity.
  6. Application: Oil and gas, marine, desalination, chemical processing or another service.
  7. Documentation: Material test certificate, inspection reports and traceability requirements.
  8. Delivery details: Destination, expected schedule and any packing requirements.

A well-defined enquiry reduces ambiguity and helps the supplier assess whether the offered material matches the requested specification.
