The Nickel Institute has published two new technical guides to assist in the effective use of nickel-containing materials.

Alloy selection for service in sulphuric acid (10057) reviews the corrosive effect of sulphuric acid at all concentrations, and the influence of contaminants on its corrosivity with a range of materials including  steels, stainless steels, nickel-base alloys, lead, titanium, zirconium and tantalum under various conditions. It also briefly discusses sulphuric acid manufacture from three possible feedstocks.

Alloy selection for service in hydrogen fluoride, hydrofluoric acid and fluorine (10074) examines the corrosive effect of fluorine, hydrogen fluoride and hydrofluoric acid with a range of materials including steels, stainless steels, nickel-base alloys, copper-base alloys, titanium, zirconium and tantalum under various conditions.

These fully revised technical publications from the Nickel Institute provide a useful guide for materials engineers.
