General Properties

SMO 254 is a very high end, molybdenum and nitrogen alloyed super austenitic stainless steel with low carbon content. It demonstrates outstanding resistance to pitting, crevice corrosion stress cracking, and corrosion fatigue uniform corrosion. SMO 254 is substantially stronger than the common austenitic grades, with strength nearly twice that of 300 series stainless steel. It is also characterized by high ductility and impact strength. With high levels of chromium, molybdenum, and nitrogen, SMO 254 is frequently used in high chloride environments, such as brackish water, seawater, pulp mill bleach plants, and other chloride process streams. In some applications it has even been found to be a more cost effective substitute for high nickel and titanium alloys.

Applications:

Due to its high levels of molybdenum and nickel, SMO 254 is frequently used in high chloride environments. Examples of applications that call for the used of SMO 254 include:

• Petroleum production
• Saltwater handling
• Food and chemical processing equipment
• Pulp mill bleach systems
• Flue gas desulphurization scrubbers
• Tall oil distillation columns
• Offshore oil & gas production equipment
• Desalination equipment
