Hastelloy C2000 Fasteners exhibit exception resistant to sulphuric acid along with hydrchloric anc hydrofluoric acids. This alloy has a deliberate copper addition which enhances its resistance to sulfuric acid to great extent. Boltport Fasteners offers all types of bolts, screws, stud bolts, threaded rods, nuts, washers and custom bolting in Hastelloy C2000.
The technical objective of the design of Hastelloy C-2000 was even greater versatility, as compared with the traditional Ni-Cr-Mo alloys. This was accomplished by use of a high chromium content (23%), a high molybdenum content (16%), and a small but effective addition of copper (1.6%). The copper was found to provide enhanced temperature capability in sulfuric acid, hydrofluoric acid, and dilute hydrochloric acid. A Ni-Cr-Mo-W alloy, C-22 offers resistance to pitting, stress-corrosion cracking, and crevice corrosion.
