Hastelloy B2 Fasteners

Hastelloy B2 has molybdenum as the principal alloying element with nickel and is known for its effective resistance to corrosion commonly caused in reducing environments, including hydrogen chloride gas in medium conditions and the acidic mediums of sulfuric, acetic, and phosphoric acids.

One principal characteristic of the UNS N10665 bolt is its resistance to pure sulfuric acid and several other non-oxidizing acids. It serves excellently even in these reductive environments, but one should not use it in oxidative environments or media that are reducing and contain oxidizing contaminants. For example, Alloy B2 Hastelloy Fasteners may incur premature failure with iron or copper in a system with hydrochloric acid. The super resistance shown to the 2.4617 Hastelloy Screws to solid chemicals such as hydrochloric acid and aluminum chloride catalysts class shall be common chemicals in the used process.

By their excellent performance in reductive media, Hastelloy B2 Screws are applied in many fields, out of which the chemical processing industry is vital for a large part, especially in the processes relating to acids: sulphuric, phosphoric, hydrochloric, and acetic acids. Hastelloy B2 Bolts also have features of excellent high strength at elevated temperatures in inert and vacuum atmospheres.

The Hastelloy Alloy B2 Fasteners do not take part in the precipitation of grain boundary carbides within the weld heat-affected region, and it is, therefore, most suitable for all the chemical process applications in the as-welded form. In the weld fittings made out of the Hastelloy B2 for welding, carbides do not take shape in the affected zone. If the precipitation does occur in the heat-affected part, the amount of rainfall is lessened enough not to jeopardize the situation of uniform impenetrability to the corrosive.

Hastelloy B2 Nuts offer high resistance to localized corrosion like pitting and chlorine-related stress corrosion cracking. These fasteners perform effectively in high temperatures roughly about 1500°F, depending upon the environment of the end use of the applications varying from ambiance to room temperature.
