Kencotube is an approved manufacturer & Trader of SMO 254 Pipe Flanges, which are an austenitic stainless steel with high molybdenum content. The physical properties of Alloy 254 Flanges (UNS S31254) are essentially equivalent as described herein. Alloy 254 Pipe Flanges may offer a cost effective solution to Nickel and Titanium alloys in these environments. 254 SMO Flanges is designed with a combination of impact toughness resistance to chloride stress corrosion cracking, and pitting and crevice corrosion with strength that is twice that of the stainless steel 300 series. Coupled with Copper and Nickel this gives 254 SMO Pipe Flanges an excellent resistance to crevice and pitting corrosion, particularly in atmospheres comprising halide ions, such as chloride, fluoride and bromide solutions.
Stainless steel Grade 254 SMO Flanges is quite tough to machine due to the extremely high work hardening rate and lack of sulfur content; however using sharp tools, overpowered machine tools, positive feeds, good amount of lubrication, and slow speeds tend to provide good machining results. Due to its high nitrogen content, Stainless steel Grade SMO 254 Flanges has higher mechanical strength than most other austenitic stainless steels. Also known as 6 Mo Flanges, it is characterized by high ductility and impact strength as well as good weldability.6 Mo Pipe Flanges is generally used as anauxiliary in perilous components of superior constructions where SS 316L or SS 317L has botched by pitting, chloride SCC or crevice attack.
