Table Of Content
SS 309 Grade Sheet, SS 309S has a lower carbon content than grade 309, which results in superior formability and weldability. Comparatively speaking to other grades, the Grade 309H has a medium carbon concentration. Additionally to having a strong tensile and creep strength at high temperatures, SS 309H Plates have outstanding oxidation resistance.
SS 309 Sheets are available as Plain, Shim or Perforated forms. It exhibits excellent heat resistance in oxidizing, nitriding and carburizing conditions. Its surface is rust free and pit free due to effective resisting property in atmospheric conditions. Higher carbon enhances SS 309H These strips are more resistant to the marine sector. These Sheets & Plates are applied in many different applications, including furnaces, petroleum refining, waste treatment, paper mill equipment, power generation, thermal processing, and more.
SS 309 Plates are widely used in corrosive temperature ranges that is influenced by sulfur content. Consequently, it is working in a higher thermal range with continuous service as well as intermediate use in peak temperatures. Chromium is added with adequate quantity to gain higher heat and corrosion resistance. SS 309 Coils are strip, ring and other types. It is more durable due to its efficient serviceability and strength. It can sustain large stresses with cracking and rupture strength with efficient enhancement.
SS 309H Plates are frequently used in surroundings in contact with acetic acid and citric acid, SS 309H Coils are protected in sulfur dioxide, and ammonia due to excellent efficiency found uses in furnaces, paper mills, thermal equipments. SS 309H is excellently strong and retains toughness at room temperatures as well as high temperatures.
