Characteristics of steel grade Alloy 254SMO / S31254:
Alloy 254 SMO is an austenitic stainless steel alloy with high resistance to general, pitting and crevice corrosion due to
its high molybdenum and nitrogen content. Alloy 254SMO was developed specifically for the pulp and paper industry and
for offshore use on oil and gas platforms. Alloy 254 is resistant to corrosion in neutral and acidic aqueous solutions, reducing
and halogenated environments.It is superior in strength to conventional austenitic stainless steels and has good weldability.
Used to create an anti-corrosion layer on the inner surface of coated pipes used in oil and natural gas transportation systems.

Scope of application Alloy 254SMO:
Sandvik 254 SMO is a high-alloy austenitic stainless steel developed for use in seawater and other aggressive
chloride-bearing media. The steel is characterized by the following properties:
Excellent resistance to pitting and crevice corrosion, PRE = ≥42.5
High resistance to general corrosion
High resistance to stress corrosion cracking
Higher strength than conventional austenitic stainless steels
Good weldability
Nickel Alloy 254SMO / 1.4547 is a super austenitic molybdenum alloy stainless steel with high corrosion resistance.
According to this indicator, nickel alloys are significantly superior to ordinary stainless steels.
Special properties:
Steel 254SMO / 1.4547 successfully resists crevice and pitting corrosion, halides in acidic environments, resistant to
chlorides and concentrated acids. The dynamic sales of stainless steel of this grade are also explained by good
weldability, ease of forming and lack of magnetic properties. The maximum use temperature is 400 degrees.
Areas of use :
Given the unique properties of the alloy, which perform well in the most difficult conditions, it is possible to buy stainless
steel sheet or pipes for use in welded structures, pipelines, heat exchangers operating in salt water, for example, on
desalination plants or offshore platforms. It is also used for the manufacture of equipment for the pulp and paper and oil
and gas industries, the chemical industry, flue gas cleaning, storage tanks and the production of aggressive liquids.
Chemical composition of steel 1.4547
Sandvik 254 SMO is used in the following applications:
Equipment for handling of seawater, such as seawater cooling, cooling water pipes, ballast water systems,
firefighting systems etc.
Hydraulic and instrumentation tubing
Equipment in pulp bleaching plants
Components in gas cleaning systems
Tanks and pipelines for chemicals with high halide contents
