We at accurate metals & alloys are esteemed in producing Industry-Acknowledged Duplex Steel S32205 sheets/plates. With a daily increase in the metal sheet industry, Stainless steel is the most comprehensive material of choice and hence our goal is to provide the best Industry grade Stainless steel sheets. The perfect mix of Nickel and Chromium with Iron helps in resisting the deterioration of the alloy. With a minimum of 18% Chromium and an 8% Nickel, S31803 grade stainless steel can contain carbon up to 0.07%, this alloy is one of the most versatile materials for a lot of suitable work. It also exhibits high ease of fabrication and superlative Formability. Duplex Steel S32205 Sheets/Plates have a wide array of usage because of their availability in different forms and finishes. From Mechanically Brushed finishes to Mill Finishes, Duplex Steel S31803 sheets/plates are also available in textures finishes, hence they are suitable for use not only indoor but also outdoor usage. It has higher durability because of high oxidation and corrosion resistance and can be used deep drawn and under marine conditions. It can resist Oxidation in infrequent service up to 870°C and 925°C in Continuous service. An Effective price point of these sheets makes these plates favorable for standard use.

GENERAL CHARACTERISTICS :
1. PREN value 34 (Pitting Resistance Equivalent Number: %Cr +3.3*%Mo+16*%N)
2. It is an extra Low Carbon Duplex Stainless steel,
3. Its yield strength is nearly twice as that of the Austenitic Stainless Steels.
4. It has good weldabilitywith minimal inter-granular corrosion in as welded condition.
5. It has high resistance to SCC in chloride and in hydrogen sulfide containing environments.
6. Exhibits high resistance to corrosion fatigue, pitting and crevice corrosion and erosion-corrosion.
MACHINABILITY :
• Cutting procedures with high speed steel tools are same as for AISI 316.
• With carbide tipped tools, the cutting speeds should be 40% less than for AISI 316 in roughing operations and 20% less for finish machining.
FABRICABILITY :
• Nearly twice the force is required to initiate plastic deformation compared to that required for AISI 304L and 316L.
• Plastic deformation proceeds as easily as in Austenitic stainless steel beyond yield strength.
• It can be cold bent to 25% deformation without requiring subsequent heat treatment.
• Bending should be followed by annealing if the service conditions are prone to SCC.
• Hot bending maybe carried out in the range 950-1100 deg C and should be followed by quench annealing.
• Normal expanding methods can be used while expanding its tubes, but higher initial force is required and it should be completed in a single operation.
WELDABILITY :
• It is welded easily by Manual Metal Arc Welding (MMAW) using covered electrode, (GTAW), Gas Metal Arc Welding (GMAW).
• Heat input should be in the range of 0.5-2.5k1/mm
• Interpass temperature should be held to 150 deg C max.
• Preheat or postweld heat treatment is normally not required.
• Typical Filler metals are overalloyed with nickel like E2209.
• Welding with carbon steels, other stainless steels and nickel alloys is readily achieved.
CORROSION RESISTANCE :
• Has better general corrosion resistance as compared to AISI 316L and 317L
• Welded joints easily pass inter-granular corrosion testing as per ASTM A262 Practice E-Strauss Test.
• Better resistance to pitting and crevice attack than 304 and 316 at higher temperatures and chloride contents.
• The combined high strength, hardness and corrosion resistance provide 2205 with superior corrosion fatigue and erosion / corrosion resistance.
APPLICATION :
• Chemical Industries Pumps, fans, centrifuges, sulphur melting coils,
• Chemical tanks
• Pulp & Paper Industries
• Digester in sulphate and sulfite plants, blow tanks, blow lines
• Petrochemical Industries
• Power Generation Industries
• Oil & Gas Industries
• Desalination
• Architecture and Construction
• Food Processing Equipment
• Biofuels plant
• Cargo tanks for ships and trucks
