Based in the industrial heart of Hamilton, New Zealand, Hemi Metals stands as a trusted manufacturer and supplier dedicated to delivering exceptional materials for demanding industries. We are proud to offer high-quality Haynes 718 bars and rods, a superalloy known for its incredible strength and reliability. Our team understands the critical nature of your projects, which is why we ensure our Haynes 718 products meet the most stringent standards, providing a dependable solution from our local foundry directly to your workshop.
Haynes 718 is a nickel-chromium alloy strengthened with significant additions of niobium and molybdenum, alongside smaller amounts of aluminum and titanium. This sophisticated composition gives it outstanding mechanical properties, including remarkable yield strength and tensile strength that hold up exceptionally well under extreme heat. It also maintains excellent creep rupture strength, meaning it can withstand constant high stress over long periods without deforming, making it incredibly durable in the most challenging environments.
Haynes 718 rods are available in various sizes, typically ranging from 0.125 inches (3.175 mm) to 4 inches (101.6 mm) in diameter, with lengths customizable based on customer requirements.
Yes, Haynes 718 rods can be customized in size and length according to specific requirements. Manufacturers often provide custom machining or cutting services to meet the desired specifications.
Haynes 718 bars and rods perform exceptionally well in high-temperature environments, maintaining strength, resistance to oxidation, and excellent fatigue properties up to 1300°F (704°C), making them ideal for aerospace applications.
The unique capabilities of Haynes 718 make it the material of choice for some of the world’s most demanding applications. You’ll find it at the heart of gas turbine engines, in critical components like discs, blades, and fasteners, where heat and stress are immense. Its resistance to corrosion also makes it ideal for use in the chemical processing industry, as well as in nuclear reactors and spacecraft. Essentially, anywhere that requires a material that won’t back down from extreme pressure and temperature, Haynes 718 is on the front lines.
