Abstract
A method of treating a valve body is disclosed herein. The method includes using a medium carbon steel, and treating the valve body to a carburizing heating step, an intermediate annealing step, a hardening step, and a tempering step. These steps provide a durable valve seat surface for the valve body such that the valve seat can withstand the conditions that involve high friction or otherwise intense operating conditions, such as oil and gas applications.
