    Product Description

    Stainless steel grade 254SMO, UNS S31254, 1.4547 is a very high end austenitic stainless steel. 

    It is designed with a combination of impact toughness resistance to chloride stress corrosion cracking, and pitting and crevice corrosion with strength that is twice that of the stainless steel 300 series.

    For certain applications, grade 254SMO, UNS S31254, 1.4547 has been reported to be a cost-effective substitute for high nickel and titanium alloys. It is known to possess excellent workability as well.

    The following sections will discuss in detail about stainless steel grade 254SMO.

    Yuhong Group, as a professional manufactuer of 254SMO, UNS S31254, 1.4547 materials, we can produce pipes and fittings, flanges. Our products have already exported to many oversea customers.

    Such as: Vietnam, Singapore, Malaysia, Indonesia, Australia, Thailand, Italy, Germany as well as Spain, France etc..


    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

    *The PRE is defined as, in weight-%, PRE = %Cr + 3.3 x %Mo + 16 x %N

    Approvals

    • UNS S31254 (254SMO) in the form of seamless pipe has been approved by the American Society of Mechanical Engineers (ASME) for use according to ASME Boiler and Pressure Vessel Code section VIII, div. 1. However, there is no approval for UNS S31254 in the form of seamless tube, but according to the ASME paragraph UG-15 it is allowed to use the design values for seamless pipe according to ASME section VIII, div. 1 also for seamless tube.
    • NACE MR 0175 (sulphide stress cracking resistant material for oil field equipment).

    Applications

    SMO 254 that is used and manufactured is widely used for seawater applications like cooling water pipes, cooling seawater, ballast water systems, and systems fighting the fire. They are also widely seen in components in gas cleaning systems. One can see its applications in desalination equipment, food processing equipment, chemical processing equipment, pulp mill bleach systems and many more related to heavy industries. Due to their availability from the manufacturers in various forms like pipe fittings, tube fittings, flanges, seamless pipes and tubes, their application gets wider and can be seen in a wide range of industries.
