ASTM A240 Gr 309 Plate and DIN 1.4828 SS Coil Manufacturer In India


The application of stainless steel 309 is seen in high temperature equipment such as Boiler baffles, Fire box sheets, Furnace components as well as in Oven linings. Preferred by buyers for its high temperature strength, the Stainless Steel UNS S30900 Plate could be used in temperatures as high as 1922°F in continuous service. Similar to most austenitic stainless steel alloys, grade 309 demonstrates excellent resistance to corrosion, especially if compared to alloy 304.

The chromium, nickel chemistry makeup of the WNR 1.4828 Sheet is suited to be used in the manufacture of equipment employed in marine environments, particularly because the alloy is more resistant to marine water and brine solutions than Alloy 304. Because the Stainless Steel 309 Sheet & Plate is used at higher temperatures, manufacturers of various high temperature applications are able to take advantage of their slow reaction time to oxidation corrosion. The inclusion of chromium and nickel in the alloy of ASME SA240 Stainless Steel 309 Plate, slows down the rate of corrosion. Unlike austenitic alloy 304, grade 309 is stainless steel that exhibits high resistance to media that contains sulfite liquors. Moreover, the AISI SS 309 Plates could be used in sulfur containing environments, where the temperature of the application can rise up to 1832°F. In instances, where the alloy is heated to a temperature range between 1202°F – 1742°F the SS 309 Sheet may become prone to a sigma phase precipitation. To combat this issue, a solution annealing treatment could be performed at 2012°F  – 2102°F. The solution annealing treatment will restore a degree of toughness to the Stainless Steel 309 Plate. Another important characteristic of the alloy is that it has Good scaling resistance when used either continuously or in intermittent service.
