A process to manufacture an oilfield component, the process comprising: selectively reinforcing a base material with an age-hardenable clad material; and age-hardening the clad material for a selected time and at a selected temperature profile; wherein the age-hardening results in the clad material developing a selected strength gradient; wherein the base material comprises a snap-tempered forging; the process further comprising finish tempering the oilfield component at a selected time and a selected temperature to temper the base material and age harden the clad material; and wherein the age hardening comprises selectively heating at least a portion of the clad material such that the clad material age-hardens and the base material remains below a tempering temperature of the base material.
