Duplex Steel Round Bar are recognized for superior general, localized as well as stress corrosion resistance properties with high strength and impact toughness which makes these deliver optimum performance in various applications.

With superior lower thermal expansion as well as higher thermal conductivity, these come with yield strength which is about twice of austenitic stainless steel. These steel round bars also feature excellent mechanical strength as well as corrosion resistance that also allows for lighter construction as well as in achieving compact system designs.

Application
Industrial fabrication as well as in other general construction and fabrication based applications. The superior duplex micro-structure also helps in improving stress related corrosion cracking resistance of steel.

Duplex Steel Flats are available in austenite as well as ferrite composition. The yield strength is double in case of austenitic stainless steel, thus the flats made from duplex stainless steel are well utilized in supporting desired loads.

Properties

• Stress resistant
• Corrosion resistant
• Excellent toughness
• Superior erosion fatigue
• Lower thermal expansion

Further, the superior mechanical strength of these steel flats also allows lighter construction as well as follow-up of compact system design finish. The presence of superior duplex micro- structure also allows for improved stress corrosion cracking resistance.

Duplex Steel Plates possess excellent resistant against corrosion and feature superior mechanical strength that makes these deliver longer service life. Providing better construction support in comparison to carbon steel as well as conventional stainless steel, the superior mechanical strength of these duplex steel plates also makes these lighter in construction as well as more compact in terms of finish. Further, the superior duplex micro-structure also provide improved stress corrosion cracking resistance as desired by the customers.

Application
These can be used in pressure vessels, heat exchangers, in construction of effluent scrubbing systems, in construction of bleaching equipment & stock-handling systems, in construction of fans, shafts, press rolls, in construction of cargo tanks, in construction of bio-fuel plants and others.

Available Standards : ASTM, ASME, SA 240
Available Grades : S 32550, S 32750, S 31803, S 32205, S 32760.

Duplex Steel Fasteners provide effective resistance against corrosion as well as also feature superior mechanical strength that makes these deliver optimum functionality in fastening applications.

Further, the superior corrosion resistance support also allows for more up-time in comparison to conventional as well as carbon steel. The superior mechanical strength of the fasteners made using this metal also allows for achieving lighter construction standards as well as achieving compact designs.

The steel fasteners also feature yield strength which is about twice that of austenitic stainless steel, thus not only saving on weights but also making the construction more cost competitive. The presence of duplex micro-structure also allows improving the stress corrosion cracking resistance of stainless steel.
