Features of Alloy 718 Round Bar
718 is a high-strength, corrosion-resistant nickel-based superalloy that is commonly used in applications requiring high temperature and pressure resistance.
Here are some features of 718 round bar:
High strength: 718 round bar has excellent tensile and yield strength, even at high temperatures.
Corrosion resistance: 718 round bar is highly resistant to corrosion and oxidation in both reducing and oxidizing environments.
Heat resistance: 718 round bar can withstand high temperatures up to 1300°F (704°C) without losing its mechanical properties.
Fatigue resistance: 718 round bar has high fatigue resistance, making it suitable for use in aerospace and other high-stress applications.
Weldability: 718 round bar can be welded using various techniques, including gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and plasma arc welding (PAW).
Machinability: 718 round bar has good machinability, but it can be difficult to machine due to its high strength and hardness.
