Abstract
Corrosion resistant alloys in fluid ends to prolong the life of a well service pump. Methods of using such corrosion resistant alloys that provide a fluid end that has a corrosion resistant alloy having a fatigue limit greater than or equal to the tensile stress on the fluid end at maximum working pressure in the fluid end for an aqueous-based fluid; installing the fluid end in a well service pump; and pumping the aqueous-based fluid through the fluid end.
