Manufacturer & Supplier of Stainless Steel 904L Flange


The nickel chromium molybdenum alloy offers the material with excellent corrosion resistance and strength. It has good mechanical qualities as well, with a minimum yield strength of 220 MPa and a minimum tensile strength of 490 MPa. The melting point of the material is also high, at 1350 degrees Celsius. The Alloy 904L Blind Flange is used to close off the end of a pipe, usually permanently. The steel is a low-carbohydrate version of the 904 grade. This means that welding and shaping operations on these flanges are simple and without the risk of grain formation and intergranular corrosion caused by carbide precipitation during the welding process.

A plate is connected to the SS 904L Plate Flange to provide more area for welding, bolting, and other attaching methods. The flanges are manufactured to ASTM B649 specifications, with numerous standards such as ANSI, ASME, DIN, and EN. These flanges come in a variety of diameters and pressure ratings, ranging from 12 inches to 48 inches. Weld neck raised face flanges are ASME SA182 SS 904L WNRF Flanges. These flanges have welded necks and elevated faces for additional strength, and they come in pressure classifications ranging from 150 to 2500 psi and PN6 to PN64. Pharmaceutical, petrochemical, maritime, sea water, and power generating are just a few of the sectors that use these flanges. Heat exchangers, boilers, condensers, paper and pulp industries, offshore oil drilling, and chemical and sea water equipment manufacture all employ SS DIN 1.4539 Nippo Flanges. We have a wide range of SS UNS N08904 Industrial Flanges available to fit any need. For more product information and price, please contact us.
