Kencotube is renowned manufacturer& Stockiest for SMO 254 Round Bars, which is a high-alloy austenitic stainless steel developed for use in seawater and other aggressive chloride-bearing media. The physical properties of 254 SMO Bars are essentially equivalent as described herein. 254 SMO Rods is an austenitic stainless steel with high molybdenum content. Alloy 254 Round Bars have a very limited applicability in environments which contain halide ions, e.g. chloride, bromide and fluoride solutions. For certain applications, Alloy 254 Bars have been reported to be a cost-effective substitute for high nickel and titanium alloys. It is known to possess excellent workability as well. Alloy 254 Rods was developed with a view of offering a less expensive alternative. Coupled with Nickel and Copper this gives SMO 254 Bars a good resistance to pitting and crevice corrosion, especially in environments containing halide ions, e.g. chloride, bromide and fluoride solutions.
SMO 254 Rods 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. Grade 254 SMO Round Bars is frequently used in high chloride environments, such as brackish water, seawater, pulp mill bleach plants, and other chloride process streams. In some applications, Grade 254 SMO Bars has even been found to be a more cost effective substitute for high nickel and titanium alloys.
