Hastelloy Fasteners

What are Hastelloy fasteners, and what makes them different from other fasteners?

Hastelloy fasteners are a specific type of fasteners that are made from alloys belonging to the Hastelloy family. Hastelloy is a trademark of Haynes International Inc. and refers to a group of nickel-based alloys exhibiting excellent corrosion resistance and high strength in extreme environments. That makes them particularly well-suited for applications in industries such as chemical processing, oil and gas, aerospace, and marine environments where exposure to harsh chemicals or extreme temperatures is common.

Additionally, Hastelloy fasteners offer excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, further enhancing their reliability and durability in demanding conditions. The unique combination of corrosion resistance, high strength, and reliability makes Hastelloy fasteners a preferred choice for critical applications where safety and performance are paramount.

What are the key properties of Hastelloy fasteners that make them suitable?

Hastelloy fasteners possess several key properties that make them highly suitable for various applications. First and foremost, they exhibit exceptional corrosion resistance. Hastelloy alloys are designed to withstand the corrosive effects of harsh chemicals, acids, and alkalis, making them ideal for use in corrosive environments. This corrosion resistance extends to uniform and localised corrosion forms, including pitting and crevice corrosion, providing added protection against potential damage.

Another important property of Hastelloy fasteners is their high strength. These fasteners are known for their excellent mechanical properties, including impressive tensile and yield strengths. This strength enables them to withstand heavy loads, high pressures, and extreme temperatures without compromising their structural integrity. As a result, Hastelloy fasteners can reliably secure components and structures even in demanding and challenging environments.

Hastelloy fasteners also exhibit good resistance to fatigue and stress corrosion cracking. That means they can maintain their performance and reliability over prolonged periods, reducing the risk of premature failure under dynamic or cyclic loading conditions.

Forging

Forging is a manufacturing process that involves shaping metal through the application of force.

Machining & Drilling

Both machining and drilling play crucial roles in the manufacturing of components across a wide range of industries.

Heat Treatment

Heating the metal to a temperature below the critical range and then slow cooling

Quality Control & Marking, Identification

Quality control and marking are essential aspects of manufacturing and production processes across metal industries.
