Deepak Steel India is a leading manufacturer, supplier, and exporter of high-quality 309/309H Stainless Steel Sheets & Plates Alloy 309 (UNS S30900) is stainless steel developed for use in high-temperature corrosion resistance functions. The alloy is non-cyclic state against oxidation of 1900 ° F (1038 ° C). Frequent cycles of low thermal oxidation resistance of about 1850 ° F (1010 ° C), Using high chromium and nickel content 309 1832 ° F (1000 ° C) may result in an atmosphere of sulphur due to alloys. This alloy is not recommended for carburizing.

It exhibits only moderate resistance to carbon sequestration for use in extreme environments. Alloys using 309 can be slightly oxidized, and perform Segmenting and thermal cycling functions, however, will reduce the maximum service temperature. Since 1202 – 1742 ° F (heated between 650 – 950 ° C) alloy charged sigma phase precipitation. A solution to announce the 2012 treatment – 2102 ° F (1100 – 1150 ° C) will restore the level of toughness.

The 309S (UNS S30908) is a low carbon alloy version. It is used for ease of construction. 309H (UNS S30909) has a great carbon modification that has been developed for better creep resistance. The enhance size and carbon particles of the plate for most cases can satisfy both the 309S and 309H requirements.
