Grade UNS S31254 is also what is known as 6% Mo is a stainless steel alloy belonging to the austenitic category. Fittings such as the Alloy 254 Elbow produced from this stainless steel grade combines moderate mechanical strength with high ductility in addition to its excellent corrosion resistance in seawater. Typically the yield strength of this material exceeds 300 MPa. For these reasons alone the SMO 254 Pipe Fittings are considered a valuable asset for use in various industrial environments. However, what makes this austenitic grade stainless steel special is that the alloy has a PREn value that ranges between 42 – 44. PREN or Pitting Resistance Equivalent is a value that determines the level of resistance a material has against pitting. Since the SMO 254 Pipe Fittings has a PREN value between 42 – 44, it indicates that the alloy’s resistance to pitting corrosion is high. The SMO DIN 1.4547 Pipe Cap, which offers good resistance to crevice corrosion; can be used at the end of hydraulic or pneumatic pipes and tubes to close a connection.

The notch ductility exhibited by the alloy at ambient and sub-zero temperature settings is very good. This high content of molybdenum in stainless steel grade 6% Mo is a reason why these fittings can be used successfully in several applications as an alternative to austenitic stainless steels, particular the 300 series, for instance, grade 316 which has superior properties. This means the characteristics of the UNS S31254 6mo Tee render them well suited to be used in applications where higher mechanical strength and/or enhanced resistance to crevice corrosion and pitting is required.
