hastelloy b is an alloy of nickel, molybdenum, and chromium that offers superior corrosion resistance in both oxidizing and reducing atmospheres. The resulting metal is highly versatile and commonly used in petrochemical, chemical processing, automotive, aerospace, and marine engineering industries.

hastelloy b is an excellent corrosion-resistant, ductile, and formable nickel alloy with a combination of strength and elasticity comparable to steel. This makes it a popular choice for process piping systems in harsh environments and other applications that require high levels of strength, corrosion resistance, and tensile strength.

It is resistant to hydrochloric acid, sulfuric acid, phosphoric acid, and acetic acid. This alloy also resists stress-corrosion cracking and knife-line attack. It is also able to withstand fluoride-bearing media and concentrated sulfuric acid, both of which are harmful to zirconium alloys.

Mechanical Properties

hastelloy b is very ductile and is a great material for welding. It can be welded without preheating or post-heating treatments, which reduces labor costs and increases production rates.

Corrosion Resistance

hastelloy b has excellent resistance to hydrochloric acid, phosphoric acid, sulphuric acid, formic acid, and acetic acid at all temperatures and concentrations. It is also resistant to chloride-induced stress-corrosion cracking and knife-line attacks.

Welding Capabilities

hastelloy b can be welded with many types of electrodes. It has a low melting point, which allows for the welding of this metal without preheating or post-heating heat treatments.

It can be forged, formed, and machined with a variety of materials. It can also be heat treated to restore its ductility and toughness without sacrificing its strength or elasticity. This treatment is typically solution annealed and includes heating to 1800degF followed by rapid quenching.
