Hastelloy B3 Fasteners

Hastelloy B3 Bolts

Hastelloy B3 Fasteners are excellent choice for bolting application in chemical processing units as the alloy exhibits exceptional resistant to hydrochloric and sulphuric acids while maintaining mechanical strength at high temperatures. Boltport Fasteners offers all types of bolts, screws, stud bolts, threaded rods, nuts, washers and custom bolting in Hastelloy B3.

Hastelloy® B3

Hastelloy B3 is a molybdenum based nickel alloy with higher structural stability at higher temperatures than hastelloy B2 alloy. Also often referred as Alloy B3; it has excellent resistance to pitting, corrosion and stress corrosion cracking in chloride-bearing solutions. Hastelloy B3 can withstand sulphuric, acetic, formic and phosphoric acids. Further it has ability to sustain well in fluoride-bearing media, which results in damage to zirconium alloys.
