Online Metals India is a trustworthy organization among the others, involved into manufacturer, supplier, and exporter of high-quality Duplex 2205 Fasteners, that are being designed as per the national and international standard quality of raw materials and thus making sure of their durability and high quality.
We manufacture high standard quality of these Duplex Steel 2205 Anchor Screw and are offered in standard sizes that range from M10 TO M100 and as well in customized length. The structure of Duplex Stainless Steel UNS S32205 Panel Screw & Machine Screw Fasteners consists of austenite pools surrounded by a continuous ferrite phase.
We export Duplex Steel 2205 Hex Bolt which is the most widely used duplex stainless steel grade, which is characterized by high yield strength.
2205 is the most widely used duplex stainless steel occupying more than 80% of the Duplex stainless steel market. The 2205 alloy provides better corrosion resistance in various environments whereas 316L is generally used with the added advantage of its higher yield strength. All 2205 alloys are metallographically examined to ensure that the shipped product is free from the presence of detrimental phases such as sigma. It is often used in form of a welded pipe or tubular components. The alloy has also been applied as a formed and welded sheet product in environments where resistance to general corrosion and chloride stress corrosion cracking is important.

GENERAL CHARACTERISTICS :
- PREN value 34 (Pitting Resistance Equivalent Number: %Cr +3.3*%Mo+16*%N)
- It is an extra Low Carbon Duplex Stainless steel,
- Its yield strength is nearly twice that of the Austenitic Stainless Steels.
- It has good weldability with minimal inter-granular corrosion in a welded condition.
- It has high resistance to SCC in chloride and in hydrogen sulfide-containing environments.
- Exhibits high resistance to corrosion fatigue, pitting and crevice corrosion, and erosion-corrosion.
MACHINABILITY:
- Cutting procedures with high-speed steel tools are the 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 may be 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 a 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 a covered electrode, (GTAW), Gas Metal Arc Welding (GMAW).
- Heat input should be in the range of 0.5-2.5k1/mm
- Interface temperature should be held to 150 deg C max.
- Preheat or post-weld heat treatment is normally not required.
- Typical Filler metals are over alloyed with nickel like E2209.
- Welding with carbon steels, other stainless steel, and nickel alloys are 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
