The Stainless Steel 309H Flanges are the high-carbon grades of stainless steel flanges that provide outstanding performance in high-temperature environments because of their high carbon contents, which increase their creep strength and thermal stability. Stainless steel grade 309H has high oxidation and scaling resistances, which enable it to operate well in furnaces, heat exchangers, kilns, and other similar devices that operate at very high temperatures.
