High Corrosion Resistant Steel Plate High Impact Strength For Chemical Processing

High Corrosion Resistant 254SMO S31254 W.Nr.1.4547 Plate Sheet Strip Coil

1. 254SMO Plate Sheet Strip Coil 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.

2. 254SMO Plate Sheet Strip Coil 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

3. 254SMO Plate Sheet Strip CoilStandards:

ASTM/ASME: UNS S31254

EURONORM: FeMi35Cr20Cu4Mo2

DIN: 2.4660

4. 254SMO Plate Sheet Strip Coil Corrosion Resistance

Excellent resistance to pitting and crevice corrosion due to its high chromium, molybdenum, and nitrogen content

Has a very low carbon content, which means there is very little risk of carbide precipitation during heating

Possesses very good resistance in water containing chlorides, therefore, it is suitable for use in seawater as it can be exposed to it for prolonged periods without suffering from crevice corrosion

5. 254SMO Plate Sheet Strip Coil Processing

Weldability

Possesses good weldability

Should be done without pre-heating

If correctly performed, there will be no need for any subsequent heat treatment

Has low thermal conductivity and high thermal expansion so must minimize distortion of welded joint

Welding without filler metal results in poor strength properties

Machinability

High work hardening rate combined with a lack of sulfur makes it very difficult to machine

Slow speeds, sharp tools, positive feeds, over-powered machine tools, and ample lubrication offer the best results
