Description

Alloy 718 is a precipitation hardenable nickel chromium alloy. As the major alloy elements are molybdenum, niobium + tantalum, aluminium and titanium, Alloy 718 gives exceptionally high yield, good corrosion resistance, tensile and creep rupture properties at temperatures up to 700°C (1300F). Broder Metals Group stocks Alloy 718 in sizes from 1/2” (12.7 mm) to 4” (101.6 mm) backed up by key sizes above this core range. Our stock is bought to API 6A 718 and NACE and as such meets most application uses for the oil industry to maximise resistance to stress corrosion cracking or treated to give maximum strength and high creep resistance and weldability. Different heat treatments are available: Solution annealed and Age hardened.
