Super Duplex 2507 Plate

ASTM A240 Type Alloy 2507 Coil and Foil Manufacturer in india as per International Standard

Super Duplex stainless steel is a mixed structure of austenite and ferrite in equal ratios. It has higher molybdenum and chromium content which normal duplex steel lacks. Thus it gives a new super duplex 2507 sheet. It has greater corrosion resistance property. It contains 24% chromium and is used in the oil and gas industry on offshore platforms as well as in chemical processing industries. ASTM A240 Type Super Duplex 2507 Plate has proof stress of 550 MPa and tensile strength of 795 MPa. When used in the annealed condition, it gets elongated to 15% and hardens to 310 HB, thus providing ductility as well as toughness. The Super Duplex 2507 Hot Rolled Plate is rolled at high temperatures of 350-460 Celsius but its applications should be limited to below 316 Celsius. It has an impact energy of a minimum of 74 ft-lbs and a Rockwell hardness of 32.

ASTM A240 Type 2507 Chequered Plate works in cryogenic temperatures and has low impact properties. For instance, at -320 Fahrenheit, its impact energy is 7 ft-lbs. Similarly, its yield strength decreases to 55 ksi at 482 Fahrenheit. Another standardized plate, SAF 2507 Clad Plate is used in highly corrosive environments. They are heat-treated in 1050-1125 Celsius and cooled by either air or water, thus making their density 7.8 g/cm3. Its specific heat capacity increases with an increase in temperature.

The 5mm Thick Cold Rolled Super Duplex 2507 Sheet has thermal conductivity from 14 W/m C at room temperature to 20 W/m Celsius at 400 Celsius. It has a high modulus of elasticity at 300 Celsius, marked as 180 MPa equivalent to 26.2 ksi. Duplex 2507 Perforated Sheet which is equivalent to SAF, supports heat input of 0.2-1.5 kJ/mm and temperature of upto 300 Fahrenheit. This makes TIG and GTAW welding suitable for it. It is used in desalination plants and high-pressure RO-plant. SA 240 GR 2507 Shim Sheet impact strength is high but it is not recommended for applications having temperatures above 570 Fahrenheit. Secondly, it has low carbon content thus it is resistant to carbide-related corrosion. Similar in construction, SA 240 GR 2507 Coil has yield strength in the range of 330 - 500 MPa and the tensile strength 450- 700 MPa in the annealed condition. But the elongation reduces in the coil when temperature increases.

Grade 2507 Foil provides good weldability and good fatigue resistance. Thus it is used in flue gas cleaning, heat exchangers, and pressure vessels. It has the impact of 140 ft-lbs at a low temperature of -40 Fahrenheit and a yield strength of 55 ksi at 482 Fahrenheit. Alloy 2507 Strips should be annealed and quenched after hot or cold working and solution annealing requires a temperature of at least 1925 Fahrenheit.
