Hastelloy B-3 (UNS N10675)
Corrosion-resistant alloy

Hastelloy B-3 (UNS N10675)
Features
  • Hastelloy B-3 is a nickel-molybdenum alloy giving it excellent resistance to pitting, corrosion, and stress-corrosion cracking
  • It can also endure sulfuric, acetic, formic, and phosphoric acids, as well as other non-oxidizing media.
  • Alloy B-3 features thermal stability superior to that of alloy B-2
  • This alloy uses minimal amounts of Fe and Cr to avoid precipitation between 700~800℃, lowering the chance of brittleness.
