S31254 bar
Alloy S31254 bar Bar is a very high end, molybdenum and nitrogen alloyed super austenitic stainless steel with low carbon content. S31254 bar demonstrates outstanding resistance to pitting, crevice corrosion stress cracking, and corrosion fatigue uniform corrosion. S31254 bar 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. UNS S31254 Flat Bar is often referred to as a “6% Moly Bar” grade due to the molybdenum content; the 6% Moly family has the ability to withstand high temperatures and maintain strength under volatile conditions.
Sasa alloy, the leading S31254 bar manufacturer and exporter in China has vast experience in the manufacture of S31254 bar, precipitation hardening. These S31254 bar are used for critical operations that require superior corrosion resistance and high impact strength for high temperature. Depending upon the clients request and standard engineering practices, our S31254 bar Forged Bars are supplied as Cold Drawn, Centre less Ground & Polished, Peeled, Smooth turned or Rough turned.
