Table Of content

SMO 254 flanges are made with austenitic stainless steel with molybdenum and nitrogen in their alloy.  It has a low carbon content. The high content of these elements in its alloy provides stainless steel SMO 254 flanges exceptional resistance to corrosion. Due to the added chromium and molybdenum in their chemical composition, stainless steel SMO 254 flanges display excellent resistance to stress cracking and pitting. It has a strength of nearly twice that of other 300 series stainless steel flanges. SMO 254 flanges are commonly used in settings with high chloride concentrations, due to the high amounts of chromium, molybdenum, and nitrogen in their composition. In some applications, it is also believed to be a more cost-effective solution for high nickel and titanium alloys. Filler material is required to weld stainless steel SMO 254, which results in poor strength properties. Filler materials such as AWS A5.14r ERNiCrMo-3 and alloy 625 are recommended. Stainless steel 254 should be annealed at temperatures ranging from 1149°C to 1204°C (2100°F to 2200°F), then quenched in water. Upsetting, forging, and other operations should be performed at temperatures ranging from 982°C (1800°F) to 1149°C (2100°F). It is best if the temperatures stay within this range as it would lead to scaling of the material. Stainless steel SMO 254 flange is used in various fields such as – Saltwater handling, oil distillation columns, fuel gas desulfurization scrubbers, components used in petroleum production, food processing equipment, and process equipment in the chemical industry, bleaching equipment in the pulp and paper industry, etc.
