Hastelloy® alloys, including C22, C2000, B2, and B3, are high-performance, corrosion-resistant materials widely recognized for their durability in aggressive chemical environments. These nickel-based alloys are engineered to meet the stringent requirements of instrumentation systems used in harsh process conditions. Their superior chemical resistance makes them indispensable in industries where reliability and precision are critical.
In instrumentation, Hastelloy alloys are used to manufacture components such as instrumentation tubing, valves, manifolds, connectors, thermowells, and pressure gauge fittings. These components are integral to systems monitoring and controlling pressure, temperature, and flow in corrosive environments. The robust chemical stability of Hastelloy materials ensures accurate data transmission and long-term performance, even under extreme operating conditions.
Hastelloy C22 and C2000 exhibit excellent resistance to oxidizing chemicals, including chlorides, nitric acid, and wet chlorine, making them ideal for mixed acid and oxidizing service. Hastelloy B2 and B3, on the other hand, are optimized for reducing environments, especially those containing hydrochloric acid. All four alloys offer excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, which are critical failure modes in instrumentation exposed to chemical attack.
The use of Hastelloy alloys in instrumentation enhances system reliability and reduces the risk of downtime due to corrosion-related failures. Their ability to maintain mechanical integrity at elevated temperatures and under high pressures makes them suitable for chemical processing plants, refineries, pharmaceutical manufacturing, offshore platforms, and waste treatment facilities. These environments often demand materials that can withstand both thermal cycling and corrosive exposure without degradation.
