Duplex Steel Pipes
Duplex Steel Pipes are well recognized for superior resistance
against corrosion as well as also bear optimum mechanical strength that
makes them deliver optimum performance support. Further, the properties like
yield strength of pipes being double of that of austenitic stainless steel,
superior general & localized stress corrosion resistance and excellent
impact toughness also makes these pipes deliver optimum performance support.
These are available with/without radiography report.
Pressure vessels, tanks, heat exchangers, effluent scrubbing systems, cargo
tanks and in bio-fuel plants.

Butt weld Fittings
Duplex Steel Butt weld Fittings possess superior mechanical
strength that allows fabricators to achieve superior construction standards
as well as compact fitted finish. Also having superior resistance against
corrosion, the presence of high corrosion resistance also allows more
up-time in comparison to conventional stainless steel. The high strength,
excellent impact toughness as well as superior resistance against general,
localized and stress related corrosion also make these fittings most
preferred in defined work areas Duplex steel Buttweld fittings are available
as per the following specifications:-

Industrial construction based applications including piping, heat
exchangers, scrubbing systems, rotors, shafts and other end areas.
Duplex Steel Round
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.
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.
- 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.
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
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.
