Stainless Steel 904L Flanges
Alloy 904L is an austenitic stainless steel grade. Flanges produced from this material have been intended for use under severe corrosion conditions, especially for environments that contain sulfuric acid. Apart from sulfuric acid, these flanges offer very good resistance to attacks in other acidic environments, particularly those containing phosphoric acid and acetic acid. In comparison to stainless steel alloy 304L as well as alloy 316L, the Stainless Steel 904L Flanges exhibit superior resistance to pitting corrosion, in addition to SCC or stress corrosion cracking and much better resistance to crevice corrosion as well. The alloying of high chromium and nickel content, in conjunction with additions of elements molybdenum and copper, prove to be vital for the corrosion resistance property of this superalloy.

ASTM A182 F904L Weld Neck Flange
Being a low carbon alloy, the ASTM B649 904L Flanges do not get corroded when welded upon by conventionally used techniques, both with and without the addition of any filler metal. And since the A182 Grade 904L WNRF Flange is required to be welded both in the inner and outer diameter of the flange, this material is regularly considered for welding based operations in applications such as heat exchangers, pollution control equipment, oil and gas well piping, chemical processing, acid production and pickling equipment. Typically after being hot worked, forgings under specification ASTM A182 such as the ASTM B649 904L Flanges are required to be cooled to a specific temperature before any heat treatment is performed on them. Which means that the heat treatment on the SS 904L Blind Flange, is to be performed in accordance with certain requirements, for instance, the kind of heat treatment given, austenitizing/solution temperature, as well as cooling media, and quenching.
