High Performance ASTM B622 Hastelloy B2 Nickel Based Alloy Pipe With High Performance
Introduction
Super alloys are also known as high performance alloys. They contain many elements in a variety of combinations designed to provide unique material properties for specific applications. These alloys can function at very high temperatures and in severe mechanical stress environments, and also where high surface stability is required. They have high creep and oxidation resistance.
Strengthening of super alloys is performed by solid-solution hardening, work hardening, and precipitation hardening methods.
HASTELLOY B-2 is a wrought nickel-molybdenum alloy that can be used in the 'as welded' condition. This alloy has excellent resistance to all temperatures and concentrations of hydrochloric acid. Additionally, it has good stress corrosion cracking and pitting resistance as well. However, due to the presence of high molybdenum content, this alloy is expensive.
