N10675 Hastelloy Alloy With Hydrochloric Acid Resistance Nickel - Molybdenum
N10675 Resists Hydrochloric Acid at All Concentrations and Temperatures
N10675 is an additional member of the nickel-molybdenum family of alloys with excellent resistance to hydrochloric acid at all concentrations and temperatures. It also withstands sulfuric, acetic, formic and phosphoric acids, and other nonoxidizing media. N10675 has a special chemistry designed to achieve a level of thermal stability greatly superior to that of its predecessors, e.g. N10665. N10675y has excellent resistance to pitting corrosion, to stress-corrosion cracking and to knife-line and heat-affected zone attack.
Application
N10675 is suitable for use in all applications previously requiring the use of N10665 alloy. Like N10665 alloy, N10675 is not recommended for use in the presence of ferric or cupric salts as these salts may cause rapid corrosion failure. Ferric or cupric salts may develop when hydrochloric acid comes in contact with iron or copper.
