Alpha Overseas offers a large selection of Duplex/ Super Duplex Sheet/ Plate of the highest quality to all our esteemed clients worldwide. Duplex and super duplex sheets and plates are valued in applications that need excellent strength and strong corrosion resistance. Low thermal expansion coefficient, high thermal conductivity, and excellent resistance to chloride stress corrosion are all features of duplex and super duplex sheets and plates. The high amounts of molybdenum, chromium, and nitrogen provide the outstanding resistance to the aperture, pitting, and general corrosion.
Duplex/ Super Duplex Sheet/ Plate are available from us in a range of dimensions, grades, lengths, kinds, ends, forms, thicknesses, widths, and surface finishes. These premium sheets are used in the petrochemical industry, offshore, marine, ship and cruise building, heat exchanger, pulp and paper industry, pipe and tube, heat exchanger, and oil and gas sector equipment.
Super Duplex Steel Plates, Super Duplex Steel Sheet Supplier, Duplex Steel Plate Manufacturers, DSS Plate, Duplex Steel Sheets, SDSS Sheet, Super Duplex Steel Plates Supplier in Mumbai, India.
We use more molybdenum and chromium in our Super Duplex plates to increase their strength and resistance. These goods are far more resistant to chloride corrosion cracking stress because of their increased austenite and ferrite composition. These plates are well suited for use in demanding tasks that require strong endurance and excellent resistance to chloride conditions. According to the needs of our esteemed clients, we provide Super duplex sheets. We use raw materials of the highest calibre to produce these sheets and plates.
The Duplex/ Super Duplex Sheet/ Plate we provide have a variety of characteristics, including good workability and weldability, high strength, a combination of ferritic and austenitic properties, a low thermal expansion rate, etc. Due to these characteristics, Duplex/ Super Duplex Sheet/ Plate are widely employed in a range of applications, including:
- Exchangers of heat
- Pipes in oil fields
- Food processing machinery
- Seawater apparatus
- Vessel for chemical processes
- Petrochemical machinery
- Washers for bleach
- Digesters for pulp mills
