Alloy family
Hastelloy Alloys — Highly Corrosion Resistant Nickel Grades
Hastelloy covers Ni-Mo and Ni-Cr-Mo corrosion resistant alloys that excel in sulphuric and hydrochloric acid, wet chlorine and mixed oxidising/reducing media. Main grades: C-276, C-22, C-2000, B-2, B-3, G-30, G-35 and X.
Why specify this alloy family
Pitting resistance
C-276 / C-22 typically PREN > 60
HCl resistance
B-2 / B-3 handle all HCl concentrations
Weldability
Low C and Si suppress HAZ precipitation
