What Are Hastelloy Sheets, Plates and Coils?
Hastelloy is an iron-nickel alloy known for its exceptional corrosion resistance, strength and durability. One key characteristic is that Hastelloy stands up well to harsh environments like acids, chlorides and oxidizing agents - making it suitable for applications within aggressive chemical processing industries where corrosion resistance is of vital importance.
Hastelloy can be difficult to machine due to its high strength and work hardening properties. Specialized cutting tools may be required in order to achieve precise shapes and dimensions; nonetheless, with the necessary expertise and equipment Hastelloy can still be machined according to individual requirements.
Hastelloy alloy offers outstanding weldability, making fabrication of complex structures and components possible. A range of techniques such as TIG (tungsten inert gas) welding and MIG welding (metal inert gas welding), resistance welding as well as TIG are applicable in creating hastelloy weldments - however proper procedures must be used so as not to compromise its corrosion resistance or mechanical properties.
Hastelloy sheets, plates and coils find widespread application throughout many industries and applications; from chemical processing plants where it's utilized in reactors and distillation columns to heat exchangers - to oil & gas platforms, pipelines and down-hole equipment subjected to highly-corrosive fluids in oil wells; aerospace components exposed to harsh environments (engine parts or fuel systems for example); as well as pharmaceutical manufacturing equipment where cleanliness and corrosion resistance is key in order to guarantee product quality and safety.
In terms of applications, Hastelloy sheets, plates, and coils find extensive use in industries such as chemical processing, oil and gas, aerospace, and pharmaceuticals. They are employed in equipment and components subjected to highly corrosive environments, such as reaction vessels, heat exchangers, piping systems, and valves. The alloy's ability to withstand aggressive chemicals and high temperatures makes it indispensable in these sectors.

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 steel by recrystallizing the deformed microstructure. Most steel is heat treated by annealing.
Cutting or Machining
Steel is cut to a specified shape and size. The steel can be sheared with circular knives, sawed with high-speed blades, or blanked with punches.
Finishing
Steels can be made with a wide variety of surface finishes. The chosen surface finish is not purely aesthetic. The type of finish is determined by the intended application.
