Stainless steel forged weld neck flange DN32 42.4 mm PN40 1.4541 / 321

Stainless steel flange, pipe outside diameter 42.4 mm, nominal pressure PN40, hole count 4, steel grade 1.4541 / 321. Theoretical weight per piece: 1.7 kg. Flanges are used wherever a detachable connection of pipeline components is required — with valves, butterfly valves, pumps, filters and other fittings. Compliant with the EN 1092-1 / DIN standard family. The weld neck flange has an extended hub butt-welded to the pipe, providing a smooth diameter transition and the highest pressure rating — used for demanding service and critical installations.

Grade 1.4541 / 321 is a titanium-stabilised austenitic stainless steel. This grade is characterised by good corrosion resistance and is often chosen for applications where resistance to elevated temperatures and good structural stability of the material are important. Steel 1.4541 is used in the mechanical engineering, energy, chemical industries and in components of installations working under more demanding thermal conditions.
