Heat Treated Inconel 718 Nickel Alloy Rod Properties
Heat Treated Inconel 718 Nickel Alloy Rod Properties
Heat-treated Inconel 718 nickel alloy bars offer high strength and ductility from cryogenic temperatures up to temperatures exceeding 750°C (1380°F). They are age-hardenable, exhibiting excellent tensile strength, yield strength, and creep-rupture properties at elevated temperatures, and exhibit higher strength at room and sub-zero temperatures. The alloy also offers good corrosion resistance to a wide range of chemicals, excellent weldability with minimal post-weld cracking, and resistance to stress corrosion cracking.
What are the advantages of INCONEL 718?
Inconel 718 is a high-strength, corrosion-resistant nickel-based superalloy. It offers excellent mechanical properties, high-temperature strength, and resistance to oxidation and corrosion. Inconel 718 is widely used in various industries, including aerospace, oil and gas, automotive, and power generation.
High-performance alloy Inconel 718 round bar inherits many of the excellent properties of nickel. Inconel 718 bar conforms to ASTM B637, which covers nickel-based hot- and cold-worked precipitation-hardenable alloys. Like most nickel alloys, the chemical composition of ASTM B637 UNS N07718 is designed for high-temperature applications. Precipitation hardening of Inconel 718 bar optimizes the alloy's tensile strength. Age hardening of Inconel 718 bar, which involves adding trace elements to the alloy before heating, is an effective method for improving the product's tensile properties.
