What Are Hastelloy B2 Bars?

Hastelloy B2 bars are high-performance nickel-molybdenum alloy bars known for their exceptional resistance to corrosion, especially in reducing environments. They offer superior resistance to hydrochloric acid, sulfuric acid, and other aggressive chemicals. These bars are widely used in chemical processing, pharmaceutical, and oil and gas industries for their reliability in harsh conditions. Hastelloy B2 bars exhibit excellent mechanical properties and are available in various sizes to suit diverse industrial applications.

Hastelloy B2 bars are an alloy made of nickel and molybdenum known for their exceptional corrosion resistance in reducing environments, particularly hydrochloric acid of all concentrations and temperatures, making them suitable for industrial uses where corrosion-causing substances such as hydrochloric acid exist. Furthermore, Hastelloy B2 bars resistance extends beyond hydrochloric acid into sulfuric, acetic, and phosphoric acids as well, making Hastelloy ideal for chemical processing equipment applications.

Hastelloy - B2 Bars

Hastelloy B2 bars boast excellent machinability characteristics when compared with other nickel-based alloys, enabling for precise shaping and customization, which facilitates use in manufacturing processes across industries that demand components with specific dimensions requirements. Their ease of machining also contributes to their versatility within various manufacturing processes.

Hastelloy B2 bars weldability makes fabrication and assembly in various applications simple and straightforward, using conventional welding techniques such as gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW) without compromise to structural integrity or system functionality. This makes their incorporation in complex structures or systems seamless without risk to their integrity or the structure itself.

Hastelloy B2 bars find multiple applications across industries including chemical processing, pharmaceuticals, oil & gas production and pulp and paper production. Common applications of Hastelloy B2 bars include reactors, heat exchangers, valves and pumps exposed to highly corrosive environments, providing superior corrosion resistance, machinability and weldability while prolonging critical infrastructure's longevity and reliability in such sectors.

Hastelloy B2 bars find widespread application across several industrial fields where corrosion resistance is essential, from chemical processing equipment like reactors and vessels, through vessels and piping systems, where exposure to corrosion-inducing substances such as acids or bases are frequent, to pharmaceutical manufacturing for equipment involved with chemical synthesis and purification processes, while being utilized extensively by oil & gas industries for downhole equipment like valves & piping systems operating under harsh environments in addition to pulp & paper manufacturing where components exposed to acidic or corrosive chemicals during production processes - making these bars indispensable components that play key roles when used during pulp & paper manufacturing where acidic chemicals or acids play key roles during production processes.

Manufacturing Process Of Hastelloy - B2 Bars

Casting

Melting and Casting

Steel and alloying metals are loaded into an electric arc furnace. Once in the furnace, the metal is heated to a specific temperature above its melting point, usually in excess of 2800°F.

Forming Round Bar

Forming

Most cast steel is formed by hot rolling—the slab, bloom, or billet is heated and passed through large rollers, stretching out the steel into a longer, thinner form.

Heat Treatment

Heat treatment

Heat treatment strengthens rolled stainless steel by recrystallizing the deformed microstructure. Most stainless steel is heat treated by annealing.

Descaling

Descaling

A rolled piece of stainless steel acquires a layer of oxidized “mill scale,” which needs to be washed away to restore a shiny surface finish.

Cutting Round Bar

Cutting or Machining

Stainless steel is cut to a specified shape and size. The stainless steel can be sheared with circular knives, sawed with high-speed blades, or blanked with punches.
