Doshi Impex India offers wide range of Duplex Steel Round Bar, Duplex Steel Round Bar is a high-strength & corrosion-resistant product available in various grades, including UNS S31803, S32205, S32750, and S32760. It is widely used in the oil and gas, chemical, and petrochemical industries, as well as in marine and offshore applications.

The features of Duplex Steel Round Bar include excellent corrosion resistance, high tensile strength, and good weld ability. It is also resistant to stress corrosion cracking and crevice corrosion, making it an ideal choice for use in harsh environments.

The usage of Duplex Steel Round Bar includes manufacturing of pumps, valves, heat exchangers, and other components used in corrosive environments. It is also used in the construction of offshore drilling platforms and production facilities.

The hardness of Duplex Steel Round Bar varies depending on the grade, but typically ranges from 22 to 34 HRC (Rockwell hardness scale). This makes it suitable for use in applications where high strength and resistance to wear and tear are required.

The types of surface finishes available for Duplex Steel Round Bar include

Black, Pickled, Bright & Polished.

The black surface finish is a result of the hot-rolling process and is typically used for non-aesthetic applications. The pickled surface finish is achieved by removing any surface scale using an acid solution, resulting in a clean and smooth surface. The bright surface finish is achieved by cold-drawing the bar through a die, resulting in a shiny and smooth surface. The polished surface finish is achieved by mechanically polishing the bar using abrasive belts, resulting in a mirror-like finish.

601 plates Inconel 601 is a nickel-chromium alloy that is highly resistant to oxidation through 2200°F. 601 alloy develops a tightly adherent oxide scale which resists spalling even under severe thermal cycling. The alloy has good high temperature strength, and retains its ductility after long service exposure. 601 alloy has good hot corrosion resistance under oxidizing conditions. 601 alloy is not suggested for use in strongly reducing, sulfur bearing environments.

For maximum oxidation resistance, 601 alloy should be welded with matching composition 601 alloy GTAW wire. 601 alloy is more difficult to machine than 304 stainless steel. Its machinability rating is 15-21% relative to AISI B1112 steel.

Alloy 2304 (UNS S32304) is a 23% chromium, 4% nickel, molybdenum-free duplex stainless steel. The Alloy 2304 has corrosion resistance properties similar to 316L. Furthermore, its mechanical properties, i.e., yield strength, are twice those of 304L/316L austenitic grades. Alloy 2304 is a 23% chromium, 4% nickel, molybdenum-free duplex stainless steel. The Alloy 2304 has corrosion resistance properties similar to 316L. Furthermore, its mechanical properties, i.e., yield strength, are twice those of 304/316 austenitic grades. This allows the designer to save weight, particularly for properly designed pressure vessel applications. The alloy is particularly suitable for applications covering the -50°C/+300°C (-58°F/572°F) temperature range. Lower temperatures may also be considered but need some restrictions, particularly for welded structures. With its duplex microstructure and low nickel and high chromium contents, the alloy has improved stress corrosion resistance properties compared to 304 and 316 austenitic grades.

Processing

Hot Forming
Hot forming must be performed in the 1150/900°C (2100/1650°F) temperature range. After forming, a new solution annealing treatment is recommended in the 950°/1050°C (2100°/1650°F) temperature range to fully restore corrosion resistance properties and mechanical properties. Parts formed with 2304 must be supported carefully during heating to avoid creep deformation.

Cold Forming
Alloy 2304 may be cold formed without any problem. The same equipment as used for the cold forming of 304L and 316L grades can be used. Due to its higher mechanical properties, including the yield strength, higher stresses are required for cold forming. A final solution annealing heat treatment is also recommended after cold forming in order to restore the mechanical and corrosion resistance properties, as described in hot forming.

Descaling
Use the same solutions and pastes as for Alloys 304L/316L. The pickling time will be higher than for austenitic grades due to the corrosion resistance properties of the alloy. 

Machinability
Alloy 2304 duplex exhibits improved machinability properties particularly when considering drilling. Its behavior is equivalent to that of 316LEZ. Furthermore, 2304 has better corrosion resistance and cleanliness properties as no sulphur additions are necessary. Localized corrosion resistance behavior is improved. 

Applications
Generally where 304 and 316L are used
Pulp and paper industry (chip storage tanks, white and black liquor tanks, digestors)
Caustic solutions, organic acids (SCC resistance)
Food industry
Pressure vessels (weight savings)
Mining (abrasion/corrosion)
