Product Description

ASTM A312 Uns S31254 (6% Moly, 1.4547) , 254mo, Alloy 6mo Cold Drawing and Cold Rolling, Stainless Stel Seamless Pipe Tube Factory

ASTM A312 Uns S31254 (6% Moly, 1.4547) , 254mo, Alloy 6mo Cold Drawing and Cold Rolling, Stainless Stel Seamless Pipe Tube Factory

Material to UNS S31254 (and the other specifications listed in our technical datasheet) is described as a 6% Mo super austenitic stainless steel.

Overview
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 sub-zero 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.
Comparisons

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).

  1. All of our stainless steel seamless pipe & tubes are packaged as per international standard to prevent any possible damage or loss. By default, we will use thick woven plastic bag to bundle the finished pipes together in batches.
  2. For some special pipes & tubes that are vulnerable to dirt, scratches, stress or rough handling, we will suggest wooden case for protection. Kindly note, wooden case can incur extra cost, not only its own cost, but also the increased freight cost, which is especially true for air transportation.
  3. For enhanced customer experience, we also provide dedicated package as per your special requirements.
