Duplex Stainless Steel Round Bar

Listing ID #646221

We are offering duplex stainless steel round bar smo 254 uns s31254.
Steel profile: 254 smo® stainless steel bar, also known as uns s31254, was originally developed for use in seawater and other aggressive chloride-bearing environments. This grade is considered a very high end austenitic stainless steel; mainly comprised of between 19.5% and 20.5% chromium, 17.5% to 18.5% nickel, 6% to 6.5% molybdenum and .18% to. 22% nitrogen. These specific levels of cr, ni, mo, and n in this “super austenitic” chemical makeup allow 31254 to combine impact toughness resistance to corrosion cracking, with pitting and crevice corrosion resistance. The result is strength of nearly twice that of 300 series stainless steels.
uns s31254 is often referred to as a “6% moly” grade due to the molybdenum content; the 6% moly family has the ability to withstand high temperatures and maintain strength under volatile conditions. This grade has surpassed its original intent and overlapped into many industries proving useful owing to its high level of molybdenum amount other elements, which allows 31254 to be used successfully in various applications such as flue gas desulfurization and chemical environments.
