SMO 254 Flanges

254 SMO Flanges

Are you looking for A182 F44 UNS S31254 Slip on Flange Manufacturer in India, Check Weight Chart and Price List of Alloy 254 Flange

The alloy used in the production of SMO 254 Flanges has a higher content of nickel along with about 6% molybdenum. In addition to these elements, copper and nitrogen are included in the alloy for SMO 254 Pipe Flanges. The alloy for SMO 254 flanges was developed, in order to resist stress related corrosion cracking, especially in those applications involving boiling chloride solutions. Since this alloy grade is relatively easy to fabricate and it has good weldable properties, these 254 SMO Blind Flanges are found in chemical processing industries, platform process systems and desalination equipment apart from offshore oil and gas industry.

In comparison to the low carbon version austenitic stainless steels i.e. grades 316L and 317L, these 254 SMO flanges demonstrate a higher tensile strength. Other properties that distinguish this alloy grade from grade 316 and 317 stainless steel is that the former has a Higher resistance to not only abrasion but also erosion and cavitation erosion.

We Supply UNS S31254 Socket Weld Flange and A182 F44 6mo Blind Flanges in Various types such as Raised Face, Flat Face.

The material also exhibits properties such as excellent ductility as well as high impact strength, which are noticed at both ambient and sub-zero temperatures. Since the SMO 254/6mo Flat Flange is non-magnetic in nature, it could be used in those applications where magnetism is not a primary concern.

Due to its important properties, these SMO UNS S31254 Industrial Flanges have been listed in MR-01-75, under applications involving oilfield, specifically speaking these flanges are used for sour service.
