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 S30409 Flanges are designed to have standardised dimensions which include ANSI, ASME, DIN, EN, BS, JIS.

Properties of AISI 304H Stainless Steel

304H Stainless Steel Cold Forming

AISI 304H is readily formed and fabricated through a full range of cold working operations. It can be used in heading, drawing, bending, and upsetting. Any cold working operations will increase the strength and hardness of the material, and may leave it slightly magnetic.

304H Stainless Steel Hot Forming

AISI 304H can be forged in the 1700-2200°F range. For maximum corrosion resistance, forgings should be annealed at 1900°F minimum and water quenched or rapidly cooled by other means after hot working operations.

304H Stainless Steel Machining

AISI 304H is a tough austenitic stainless steel subject to work hardening during deformation and, unless modified for improved machining response, is resistant to chip breaking. The best machining results are achieved with slower speeds, heavier feeds, excellent lubrication, sharp tooling, and powerful, rigid equipment.

304H Stainless Steel Welding

AISI 304H is readily welded by a full range of conventional welding procedures (except oxyacetylene). AWS E308H/ER308H filler metals should be used with Type Stainless Steel 304H. After welding Type Stainless Steel 304H it may be necessary to fully anneal to restore the corrosion resistance lost by sensitization to intergranular corrosion when chromium carbides were precipitated in the grain boundaries in the weld heat-affected zone.

304H Stainless Steel Heat Treatment

Annealing: Type Stainless Steel 304H should be heated to 1900ºF minimum and water quenched or rapidly cooled by other means.
Hardening: Type Stainless Steel 304H cannot be hardened by heat treatment. However, Type Stainless Steel 304H can be hardened by cold working.
