A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together. The principle of a flange is to apply a mechanical force by using bolts to preload the gasket until contact stress between flanges and gasket is sufficient to maintain a seal. Connection to the pipe is by welding or threading. To allow easy functionality and inter-changeability, these ASTM A182 UNS S30900 Flanges are designed to have standardised dimensions which include ANSI, ASME, DIN, EN, BS, JIS.

Properties of AISI 309 Stainlesss Steel

309 Stainless Steel Cold Forming

The alloy is quite ductile and forms in a manner very similar to 316. Cold forming of pieces with long-term exposure to high temperatures is not recommended since the alloy is subject to carbide precipitation and sigma phase precipitants.

309 Stainless Steel Hot Forming

Heat uniformly at 1742 – 2192°F (950 – 1200°C). After hot forming a final anneal at 1832 – 2101°F (1000 – 1150°C) followed by rapid quenching is recommended.

309 Stainless Steel Welding

Stainless Steel 309 can be readily welded by most standard processes including TIG, PLASMA, MIG, SMAW, SAW and FCAW.
