High toughness martensitic stainless steel and reciprocating pump manufactured therewith

Abstract

A reciprocating pump is disclosed. The reciprocating pump may comprise a power end, and a fluid end operatively connected to the power end. The fluid end may include a plunger, a cylinder configured to operatively engage the plunger, and an end block. The plunger, the cylinder, and the end block of the fluid end may each be fabricated from a high toughness martensitic stainless steel composition comprising between 11.50% and 17.00% by weight chromium, between 3.50% and 6.00% by weight nickel, between 0.30% and 1.50% by weight molybdenum, between 0.01% and 0.20% by weight vanadium, and iron.
