Stainless steel forged blind flange DN40 48.3 mm PN40 1.4541 / 321

Stainless steel flange, pipe outside diameter 48.3 mm, nominal pressure PN40, hole count 4, steel grade 1.4541 / 321. Theoretical weight per piece: 2.4 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 blind flange terminates a pipeline run and provides a removable closure — used for inspection access, pressure testing or as a permanent seal on standby branches.

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.
