Alpha Overseas manufactures SS 304 / 304L Flanges, which finds its larger demand in the soft tempers and can be used in severe corrosive environments. Entire range of our Stainless Steel 304 Flanges is procured from most reliable and trusted experts in our selling business. These SS 304 Flanges has excellent resistance to a wide range of atmospheric environments and many corrosive media. The balanced austenitic structure of our Alloy 304 Slip On Flanges enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, saucepans and hollow-ware. These Grade 304 Blind Flanges has excellent toughness, even down to cryonegic temperatures which are defined as very low temperatures. Our 304 Stainless Steel Blind Flanges resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments. If intergranular corrosion in the heat affected zone may occur, it is suggested that these SS 304L Lap Joint Flanges to be used.
