Key Material Advantages

Excellent High-Temperature Strength: Maintains mechanical properties under long-term exposure to elevated temperatures, ideal for engines and heat-intensive equipment.

Superior Corrosion and Oxidation Resistance: Performs well in harsh chemical, acidic, and marine environments, including sulfuric, hydrochloric, and seawater conditions.

Thermal Stability and Low Expansion: Iron-nickel alloys offer low thermal expansion, making them perfect for precision instruments and tooling.

Good Weldability and Machinability: Suitable for forging, rolling, precision machining, and complex fabrications.

Resistance to Stress and Fatigue Cracking: Common in cyclic loading and pressure environments like turbines and reactors.

 

Common Grades

Nickel Alloys:

Inconel Series: Inconel 600, 625, 718–High temperature and corrosion resistant
