What is 254 SMO Plate?

254 SMO Plate is a molybdenum-alloyed austenitic stainless steel developed in Sweden. It offers excellent corrosion resistance in chloride-rich environments, making it suitable for use in many chemical and maritime industries. This grade also has good formability and weldability, making it easy to fabricate into parts of equipment that require high strength, durability, and good corrosive resistance. Its high chromium levels provide excellent resistance against pitting and crevice corrosion and stress cracking corrosion when exposed to various acids. Furthermore, its high molybdenum content gives the plate superior performance in acidic environments compared with other stainless steels.


254 SMO Plate is a stainless steel plate alloy featuring high levels of chromium, molybdenum and nitrogen. Due to its increased chromium content, it offers superior corrosion resistance over regular austenitic stainless steel alloys. The higher molybdenum content also enhances its resistance to chloride pitting and crevices corrosion in water environments. Its nitrogen-strengthened composition makes it suitable for many marine and other applications that require enhanced mechanical properties compared with 300 series stainless steels. Furthermore, adding copper increases formability while ensuring good weldability by mitigating hot-cracking problems. Other notable features include excellent flexibility, low thermal expansion coefficient, and outstanding ability to resist stress corrosion cracking in halide environments such as seawater or chloride solutions.


The 254 SMO plate is a high alloy austenitic stainless steel developed in seawater and other aggressive chloride-bearing environments. The grade contains a high level of chromium, molybdenum and nitrogen, providing outstanding resistance to pitting, crevice, and stress-corrosion cracking. It also combines good formability and weldability with excellent toughness.

Additional characteristics include:

  • A stabilized austenitic structure which provides superior strength at elevated temperatures;
  • Good general and localized corrosion resistance;
  • Good ductility even after welding;
  • Corrosion resistance higher than standard grades, such as grade 316L;
  • Impressive mechanical strength (tensile or yield), hardness (Rockwell or Vickers), and impact toughness properties compared to other stainless steel grades available today.

In addition to these qualities, the 254 SMO plate offers excellent fabrication properties, including machinability, forming, roll forming capacities etc., making it an ideal choice for multiple applications in many key industries like food processing equipment, desalination units etc., In conclusion, this unique combination of features makes the 254 SMO Plate one of the most sought-after products in the market today.


254 SMO plate is a stainless steel alloy with excellent corrosion resistance. It applies highly to areas exposed to aggressive chloride-containing media, such as seawater, brine solutions, and other halide environments. Common applications include heat exchangers, chemical tankers, process equipment in chemical industry settings, seawater desalination plants for drinking and irrigation needs, and pipelines for transporting foodstuffs or petroleum products near the coastlines where salt corrosion could be an issue. In addition to these traditional applications, it has many uses as trim material for architectural projects such as bridges or buildings near coastal areas.


254SMO is an austenitic stainless steel designed for maximum resistance to pitting and crevice corrosion. With high levels of chromium, molybdenum, and nitrogen, 254SMO is especially suited for high chloride environments such as brackish water, seawater, pulp mill bleach plants and other high chloride process streams. 254SMO offers chloride resistance superior to that of Alloy 904L, Alloy 20, Alloy 825 and Alloy G. 254SMO is compatible with the common austenitic stainless steels. It is often used as a replacement in critical com- ponents of larger constructions where Type 316L or 317L has failed by pitting, crevice attack, or chloride stress corrosion cracking. In new construction, 254SMO has been found in many cases to be a technically adequate and much less costly substitute for nickel-based alloys and titanium.

254SMO is substantially stronger than the common austenitic grades, but is also characterized by high ductility and impact strength. 254SMO is readily fabricated and welded.
