Kencotube has huge industrial experience and depth in knowledge of Stainless Steel 904L Flanges, which is non-stabilized austenitic stainless steel which has low carbon content compared to the standard ones. Stainless Steel 904L Pipe Flanges is designed to be used in severe corrosive conditions, and particularly for sulphuric acid, where its application has been proved time and again. As per structure from within, SS 904L Pipe Flanges is less subtle to crack phases and precipitation ferrite than the usual austenitic ones that have soaring content of molybdenum. Alloy 904L Flanges contains relatively high contents of chromium, nickel, molybdenum and copper and hence has superior resistance to general corrosion, particularly in sulphuric and phosphoric conditions. Alloy 904L Pipe Flanges hardens to a good extent when subjected to purposeful cooling or cryogenic conditions.
Although they can be solution heat-treated and then made to cool down rapidly for hardening, 904L Stainless Steel Pipe Flanges never responds to heat treatment. For applying maximum corrosion resistance, filler metals of equal of higher alloy content are used, becausethese 904L Stainless Steel Flanges is of high purity with low sulphur content. Annealing is not necessarily carried out in Grade 904L Flanges, but must be done in order to counter when the fabrication is performed under severe stress which can possibly lead to severe stress cracking conditions. Grade 904L Pipe Flange sare commonly found on pump covers and Valve Bonnets. Meanwhile, these flanges are offered to our clients in different sizes and shapes at reasonable price.
