Hastelloy B2 fasteners are made from a high-performance nickel-molybdenum alloy, specifically designed for its superior resistance to a wide range of corrosive environments. It is composed primarily of Nickel (66%), Molybdenum (28.8%) and Iron (5.5%). The alloy also contains trace amounts of Manganese, Silicon, Carbon, and Phosphorus. Due to its complex chemical composition, Hastelloy B2 fasteners possess superior strength and durability against the harshest elements. Its ability to withstand extreme temperatures and harsh chemicals makes it the go-to option in many corrosive settings, especially those exposed to sulfide stress cracking making it perfect for industries such as oil & gas extraction where reliability is paramount.
Hastelloy B2 fasteners are corrosion-resistant alloy fasteners widely used in sulfuric and hydrochloric acid applications. They offer excellent resistance to localized attack by reducing agents like forms and ferric chlorides. Due to their excellent mechanical properties, B2 Hastelloy fasteners can be hot-formed, machined cold, or welded using appropriate welding techniques. In addition, they have exceptional performance in high-temperature service ranging from cryogenic temperatures up to 1000°F (538°C). Thus, Hastelloy B2 fasteners are perfect for scenarios that require excellent corrosion resistance, incredible strength at ambient and elevated temperatures, and good dimensional stability.
