Stainless and acid-resistant steel flanges for joining pipelines: weld neck, slip-on, blind and lap joint. Choose a flange type or narrow the list with the pipe diameter, nominal pressure and steel grade filters.

Steel grades

Each grade has its own page with chemical composition, equivalent designations and the full list of products in stock.

Acid-resistant

Austenitic with molybdenum – resistant to pitting and crevice corrosion; for chemicals, processing and chloride environments.

Austenitic stainless

Chromium-nickel without molybdenum – the standard choice for structures, food service and interiors.

Heat-resistant

Higher chromium and silicon – retain strength and scaling resistance at high temperatures.

Ferritic

Chromium without nickel – cheaper, magnetic, good where atmospheric corrosion resistance matters.

Duplex

Austenitic-ferritic structure – twice the yield strength with good stress corrosion resistance.
