Inconel 725 (UNS N07725)
Category: INCONEL
Overview
Inconel 725 (UNS N07725) is a nickel based alloy which is highly resistant to many aqueous environments and is age hardenable for extremely high strength. It has essentially the same corrosion resistance asInconel 625, which is widely used in a broad range of severaly corrosive environments.
Inconel 725 fills the need for greater environmental cracking resistance at high temperatures in deep, extremely hostile, oil and gas production environments. It offers better cracking resistance at elevated temperatures in higher levels of H2S due to the higher content of molybdenum.
