Inconel 718 Plates: High-Performance Nickel Alloy for Extreme Environments
Product Overview
Inconel 718 (UNS N07718) is a high-strength, corrosion-resistant, precipitation-hardenable nickel-chromium alloy, well-known for its outstanding mechanical properties at elevated temperatures. This alloy is primarily used in applications where performance is critical, such as in aerospace, power generation, chemical processing, and marine industries. Inconel 718 offers high strength and resistance to oxidation and corrosion, even under extreme environments.
One of the most notable characteristics of Inconel 718 Plates is their excellent resistance to both oxidizing and carburizing environments. The alloy maintains its strength across a wide temperature range, up to 1300°F (704°C), making it highly suitable for jet engines, gas turbines, and other high-temperature applications. The ability of Inconel 718 to withstand complex stress and fatigue loads in both high- and low-temperature environments, along with its outstanding weldability, makes it a top choice in critical applications across industries worldwide.
Inconel 718's properties can be further enhanced through heat treatment. The precipitation hardening process increases its strength significantly, making it one of the most reliable materials for structural components that need to endure harsh and demanding conditions.
