Whether you need to connect two pieces of equipment or you need a flanged joint, you can choose grade 309H - Stainless Steel Forged Flanges. These flanges have an easy access port for cleaning, inspection, and modification. Flanged joints are made by bolting two flanges together, and a gasket seals the joint. 


These flanges are readily available for industrial use, and they feature excellent welding characteristics. You can easily weld them together, and no post-weld annealing is necessary unless the thickness of the section being joined is too thin.


ASTM A182 specifies the chemical composition and mechanical properties of forged 309H stainless steel. This specification covers forged products, as well as supplementary requirements for the material.


These flanges come in various sizes, shapes, and thicknesses. You can choose from forged and seamless 309H & 310H flanges. These flanges can be manufactured by several approved companies. Whether you need a forged or a welded flange, we have what you need.


AISI 309H - Stainless Steel Forging flanges are the ideal choice for many applications. This high-grade steel is used in high-temperature processes, such as in the aerospace and nuclear industries. This steel is heat-resistant and corrosion-resistant, and it holds its strength at normal and increased temperatures. Alloy 309H and 309S flanges are highly versatile and can be welded and processed using common fabrication practices.
