Whats is 254SMo material?
Designated as UNS S31254 or DIN W.Nr. 1.4547, 254SMO is an Cr-Ni-Mo alloyed super austenitic stainless steel with deliberate additions of copper and nitrogen content. With high levels of chromium, molybdenum, and nitrogen, 254SMO is especially suited for high-chloride environments and offers chloride resistance superior to Alloy 904L, SS316L, Alloy 20 and Alloy 825. It can be readily welded to other common austenitic stainless steels. The 254 SMO stainless steel provides outstanding resistance to pitting corrosion, crevice corrosion, as well as stress-corrosion cracking. It is widely used in seawater handling & desalination equipment, pulp and paper industry, oil refinery plant, chemical processing equipment, and food processing equipment, etc.
Examples of applications :
• Petroleum production
• Saltwater handling
• Pulp mill bleach systems
• Tall oil distillation columns
• Desalination equipment
• Food and chemical processing equipment
• Flue gas desulphurization scrubbers
• Offshore oil & gas production equipment
