What are the properties of 2.4668 material?
2.4668) is a high-strength, corrosion-resistant nickel chromium material used at -423° to 1300°F. Typical composition limits are shown in Table 1. The age-hardenable alloy can be readily fabricated, even into complex parts. Its welding characteristics, especially its resistance to postweld cracking, are outstanding.
What is the surface hardening of Inconel 718?
Alloy 718 is hardened by the precipitation of secondary phases (e.g. gamma prime and gamma double-prime) into the metal matrix. The precipitation of these nickel- (aluminum, titanium, niobium) phases is induced by heat treating in the temperature range of 1100 to 1500°F.
What is the hardness of 718 Inconel?
Inconel 718 hardness varies significantly with heat treatment, typically ranging from softer, machinable levels (around 20-35 HRC in the solution-annealed state) to very hard, aged conditions (up to 45-50 HRC) after precipitation hardening, offering excellent strength and wear resistance for high-temperature applications, making it suitable for aerospace and demanding industrial uses.
