Superduplex 2507 UNS S32750: high-performance CNC machining
A technical guide to Superduplex 2507 stainless steel, its equivalences, properties, industrial applications and made-to-drawing custom part manufacturing.
A material for corrosive environments and critical applications
Superduplex 2507 is a super duplex stainless steel designed to work in environments where corrosion, mechanical load and technical demand come together.
Its austenitic-ferritic microstructure, together with its chromium, molybdenum and nitrogen content, provides high mechanical strength and strong resistance to localised corrosion in chloride environments.
Material identification
What is Superduplex 2507?
Superduplex 2507, also identified as UNS S32750 or EN 1.4410, belongs to the family of super duplex stainless steels.
It is used in projects where conventional stainless steels may not provide enough resistance to corrosion, wear, pressure or chemically aggressive environments.
High strength
Designed for components exposed to high mechanical stress.
Chloride resistance
Especially useful in marine, chemical and petrochemical environments.
Good stability
Allows technical parts to be manufactured with demanding dimensional control.
Traceability
Suitable for sectors where documentation is critical.
Common designations of Superduplex 2507
In drawings, certificates or technical orders, this material may appear under different names depending on the standard or supply format.
Why it is used in critical industrial parts
