Super duplex stainless steel properties

Typical manufacturing specifications. Physical Properties (Room Temperature) . Penn Stainless inventory now includes Duplex 250 which is a super duplex stainless steel with chromium, molybdenum, .

To understand how duplex steels work, first compare the composition of two familiar. Ferritic-austenitic stainless steel also referred to as duplex stain- less steels, combine many of the beneficial properties of ferritic and austenitic steels. LDX 21 up to the super duplex grades 25and.


Outokumpu duplex stainless steels offer an excellent combination of strength.

Grades 25and 45are regarded as super duplex grades. Duplex grades combine many of the beneficial properties of ferritic and austenitic stainless steels. UNS S327F– Super Duplex Stainless Steel. Providing higher strength than both austenitic and Cr Duples Stainless Steels UNS S327(F55) is suited to a variety of applications in industries such as . Super duplex stainless steels are generally more complex, more highly alloyed materials with PREn (Pitting Resistance Equivalent number) = 40.


Trade Name, UNS, Super Duplex Industry Specifications, Chemical Composition, Min. Sandvik SAF 25is a super-duplex stainless steel characterized by very good. Sandvik SAF 25are being widely used in offshore oil and .

Very high mechanical strength; Physical properties that offer design . Duplex 25is a super duplex stainless steel designed for applications which demand exceptional. Duplex 25possesses excellent mechanical properties. As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic.


The super duplex grades are even more resistant to corrosion. In metallurgy, stainless steel, also known as inox steel or inox from French inoxydable. Stainless steel is used where both the properties of steel and corrosion resistance. Super duplex is by definition a duplex stainless steel with a Pitting . Jump to General Properties - Alloy 25is a super duplex stainless steel with chromium, molybdenum, and nickel designed for demanding . Super duplex stainless steel (SDSS) is a candidate material for production tubing.


Brown McFarlane holds stock of Super Duplex stainless steel plate specifications UNS S327(410) and UNS S327(501). Duplex stainless steels have a two-phase microstructure of austenite and ferrite grains.
