Inconel 718 is a high temperature alloy with extremely high nickel, chromium, and molybdenum contents. These pipes excel in high temperature environments with excellent strength and creep rupture resistance. Designed for cryogenic environments, 718 alloy pipes can be used in operating temperatures up to 1200 degrees Fahrenheit (about 673 degrees Celsius). These pipes also have enhanced corrosion resistance in different environments. The addition of niobium in these pipes allows for age hardening. This allows for spontaneous annealing and welding during heating and cooling cycles. These pipes are designed with a density of 8.192 g/cm3, a minimum tensile strength of 13,500 psi, and a minimum yield strength of 70,000 psi. 718 alloy pipes can elongate by 25% and have a hardness of 100 Rockwell B.
