The material produced under specification ASTM B649 is generally supplied in a solution treated manner or in cold drawn condition as required. Heat treatment to be performed on the 904l Stainless Steel Slip on Flange could be waived for forging quality material. Very often, the 904L SS Weld neck Flange can be analysed to check for conformance of its chemical as well as its product according to the ASTM B649 specification.

ASTM B649 UNS N08904 Blind Flange
904l Stainless Steel Flanges is known to resist environments containing dilute sulfuric acid. The ASTM B649 UNS N08904 Blind Flange also offers good resistance to other inorganic acids which include warm phosphoric acid as well as most organic acids. The high content of alloying elements in the 904l Stainless Steel Blind Flange offers the alloy noticeably desirable resistance to uniform corrosion. 904l is one of the few stainless steel alloy grades to have been developed to offer resistance to environments containing dilute sulfuric acid.
Additionally, the 904l Stainless Steel RTJ Flange is such an alloy that can, at temperatures as high as 95°F gives good resistance in such environments. In fact, its corrosion resistance properties are visible even when the entire concentration of the acid ranges between 0 to 100%. 904l Stainless Steel Spectacle Blind Flange also proves its resistance to intergranular corrosion and can without problems be welded as well as processed by the more conventionally used store fabrication practices.
