Hastelloy B3 (UNS N10675) Bar, plate, strip, forging, seamless pipe, welded pipe

Hastelloy B3 (UNS N10675)

• Introduction
  • Hastelloy B-3 is a nickel-molybdenum  alloy with excellent resistance to pitting, corrosion, and stress-corrosion  cracking plus, thermal stability superior to that of alloy B-2. In addition,  this nickel steel alloy has great resistance to knife-line and heat–affected  zone attack. Alloy B-3 also withstands sulfuric, acetic, formic and  phosphoric acids, and other non-oxidizing media. Furthermore, this nickel  alloy has excellent resistance to hydrochloric acid at all concentrations and  temperatures. Hastelloy B-3’s distinguishing feature is its ability to  maintain excellent ductility during transient exposures to intermediate  temperatures. Such exposures are routinely experienced during heat treatments  associated with fabrication.
