A new cost-effective nickel-based precipitation hardenable alloy has been developed to fill the need for a more economical alternative for moderate to severe sour service oilfield applications where highly alloyed nickel alloys are not required. The new alloy has been named AF935. This paper will present qualification testing for NACE environments and completion brines for Alloy AF935. The intended alloy applications include a broad range of service tool and completion components for the oil and gas industry.
