Duplex stainless steels are standardized throughout the world (ISO - ASTM - ASME - EN) for usein construction and pressure vessels.

Industeel is ISO 9001 certified and approved by DNV - LLOYD’S - ASME - TÜV - NKK - BV etc…Industeel is NORSOK Rev 3 certified for UR 2205 (S31803), UR 2507 (S2750), UR 2507W (S32760).

Tested and used in many different industrial chemicals : sulfuric, nitric, phosphoric, soda,...

Generally more resistant than the corresponding austenitics to stresscorrosion cracking in chloride containing media. Duplex are used foroil/refineries applications, in accordance with NACE MR0175 andAPI938C standards.

Excellent resistance to abrasive particles in flowing corrosive slurries.Chemical application

Duplex stainless steels can be used for buildingand construction in urban, industrial and marineenvironments.

They have also been tested in soils with differentresistivities, permeabilities and chloride contents.

From lean duplex to superduplex

Know-how from a long experience

Our production techniques, the in-service performances and our manufacturing properties knowledgeare continuously improved.

Industeel has developed duplex stainless plates for 70 years.

Our experts from our Research Center are asked on material selection, forming conditions and metallurgy aspects.

Duplex stainless steel plates, the material you need

Strong Yield strength: 400 to 600Mpa (58/87Ksi)

Ductile Elongation to rupture > 25 %

Weldable By most of the common processes

Corrosion resistant In various environments

Affordable Weight/Cost savings

Available In a wide range of plate sizes

Safe From an experienced producer

Environmentally friendly Lighter, no coating, 100 % recyclable

In spite of their higher strength, duplex stainless steelscan be sheared, bent, pressed, rolled into differentshapes, hot or cold.

Machinability varies with grade. Leaner grades are easyto machine.
