Stainless Steel 309 Plates

For applications requiring high temperatures, alloy 309 Plates/309 S Plates (UNS S309 Plates00/S309 Plates08) austenitic stainless steel is frequently utilized. Compared to the typical austenitic Alloy 304, its high chromium and nickel composition offer comparable corrosion resistance, improved resistance to oxidation, and a greater percentage of room temperature strength retention. Alloy 309 Plates can be used at temperatures up to 1832°F (1000°C) in sulfur-containing atmospheres because of their high chromium and low nickel content. Due to its modest resistance to carbon absorption, the alloy is not advised for usage in severely carburizing environments. Alloy 309S Plates can be used in applications that involve mild oxidation, nitriding, cementing, and thermal cycling, however, the maximum service temperature must be lowered. The alloy can precipitate the sigma phase when heated between 650 and 950 degrees Fahrenheit (1202 to 1742 degrees Celsius). An amount of hardness can be restored by solution annealing the material at 2012–2102°F (1100–1150°C).

The use of Alloy 309 in damp, corrosive conditions is not intended. The high carbon content, which is there to improve creep qualities, harms the ability to withstand aqueous corrosion. After being exposed to high temperatures for a long time, the alloy is vulnerable to intergranular corrosion. However, Alloy 309 Plates is more corrosion resistant than most heat-resistant alloys due to its high chromium concentration (23 percent). The alloy's reduced carbon version is 309S (UNS S30908) PLates. It is used because it is simple to manufacture. A high carbon modification called 309H (UNS S30909) was created for improved creep resistance. Most of the time, the plate's carbon content and grain size can satisfy both the 309S and 309H standards.
