SMO 254

Alloys 254 / SMO 254 / 6 Mo/ UNS S31254 is an austenitic stainless steel with a high molybdenum content. Coupled with Nickel and Copper this gives the alloy a good resistance to pitting and crevice corrosion, especially in environments containing halide ions, e.g. chloride, bromide and fluoride solutions.

254 SMO (UNS S31254) may offer a cost effective solution to Nickel and Titanium alloys in these environments.

Good formability and weldability
SMO254 has a good weldability  and the methods used for welding conventional austenitic steels are used. It is somewhat more sensitive to hot cracking and shall be welded with low heat input.

Filler metal  of type Avesta Welding P12 or  P16 are recommended. These filler metals will give a weld with a resistance to pitting corrosion. The steel can be both cold and hot formed. Due to a higher strength and alloy materials the steel is difficult to machine.

General Properties

Alloy 254 SMO 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. Alloy 254 SMO 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, Alloy 254 SMO 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, Alloy 254 SMO is frequently used in high chloride environments. Examples of applications that call for the used of Alloy 254 SMO 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
Standards:

 

  • ASTM/ASME: UNS S31254
  • EURONORM: FeMi35Cr20Cu4Mo2
  • DIN: 2.4660
