MITTEL is a special stainless steel manufacturer with 20 years of manufacturing experience.
254 SMO is a 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. 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, 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.
Duplex Stainless 254 SMo 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

Corrosion Resistance
F44 Super Austenitic Stainless Steel offers higher resistance to abrasion, erosion and cavitation erosion than other austenitic stainless grades such as 316. F44 Super Austenitic Stainless Steel has excellent resistance to corrosion in sea water and concentrated halide environments, with good resistance to crevice corrosion in seawater.
Welding
F44 Super Austenitic Stainless Steel is readily weldeable with welding procedures used for other austenitic stainless steel specifications. Welding should be carried out at the lowest heat possible as due to its austenite structure it can be prone to hot cracking.
Mill′s test certificate
EN 10204/3.1 with all relevant data reg. chem. composition, mech. properties and results of testing.
Introduction
Material to F44 Super Austenitic Stainless Steel is described as a 6% Mo super austenitic stainless
steel. The steel combines moderate mechanical strength (typically over 300 MPa yield strength) and high ductility with excellent corrosion resistance in seawater and a variety of industrial environments. Typically the alloy has a PREn(Pitting Resistance Equivalent) of 42-44 which ensures that the resistance to pitting corrosion is high. In addition, the steel provides good resistance to crevice corrosion.
Ambient and subzero temperature notch ductility is very good. These attributes mean that this high molybdenum stainless steel can be used successfully as an alternative to 300 series austenitic stainless steels (such as type 316) in applications where higher mechanical strength and/or
enhanced resistance to pitting and crevice corrosion is required. This alloy possesses a lower yield strength than that of duplex stainless steel (and much lower than that of super duplex steel) and pitting resistance which is comparable to super duplex stainless steel (such as UNS S32760 / S32750).
Applications
F44 Super Austenitic Stainless Steel is ideally suited for use in halide environments and widely used in the chemical, marine, oil and gas industries. Typical applications include pumps, valves, heat exchangers, flanges and manifolds.
