Hastelloy Bars Hastelloy bars are an iconic metal alloy known for its outstanding corrosion-resistance. Composed primarily of nickel, chromium and molybdenum atoms, Hastelloy offers superior resistance in acidic environments like acids, salts and reducing agents; making these corrosion resistant alloys especially well-suited for applications within industries like chemical processing, petrochemical and pharmaceutical manufacturing.
Hastelloy bars boast impressive corrosion resistance as well as good machinability - this means they can be worked efficiently using conventional machining techniques for the fabrication of complex components and structures. Their excellent machinability contributes to their versatility when manufacturing processes require precise machining of components or structures. Hastelloy is therefore often preferred over its rival alloys in industries requiring exact precision machining applications.
Hastelloy bars also boast exceptional weldability, making it easy and efficient for them to be joined together using standard welding methods for assembly or construction of various equipment or structures requiring welding, which makes Hastelloy more suitable in applications that demand reliable joining mechanisms to maintain structural integrity. Furthermore, Hastelloy's superior weldability further adds its value in diverse applications where reliability of joining is essential to overall structural integrity.
Hastelloy bars find diverse applications across numerous industries due to their versatile combination of properties. Common applications for Hastelloy include chemical processing equipment such as reactors, vessels and piping systems where corrosion resistance is essential; aerospace marine power generation applications; as well as marine applications in harsh conditions where reliability performance is necessary.
Hastelloy bars can be seen being utilized across industries in areas with harsh corrosive environments like chemical processing plants, oil and gas refineries and desalination plants. As structural elements in reactors, heat exchangers, valves etc., where their corrosion-resistance ensures extended service life and operational reliability; additionally their weldability makes Hastelloy ideal for custom fabrication requirements of specific applications such as corrosion resistant valves.
Hastelloy bars are used extensively in chemical plants for construction of pressure vessels, heat exchangers and piping systems where their long-term corrosion resistance ensures integrity in high pressure or high temperature conditions. Their weldability enables the efficient assembly of complex structures. In the aerospace industry, they're used in components that must endure extreme environments, such as turbine engines or aircraft exhaust systems, among those often exposed.

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
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 strengthens rolled Hastelloy by recrystallizing the deformed microstructure. Most Hastelloy is heat treated by annealing.
Descaling
A rolled piece of Hastelloy acquires a layer of oxidized “mill scale,” which needs to be washed away to restore a shiny surface finish.
Cutting or Machining
Hastelloy is cut to a specified shape and size. The Hastelloy can be sheared with circular knives, sawed with high-speed blades, or blanked with punches.
