SPECIFICALLY FORMULATED FOR SHALLOW TO MEDIUM DEPTH WELLS AND/OR LIGHT TO MODERATE ROD LOADS

The grade K sucker rod is manufactured from modified UNS G43200 nickel-chromium-molybdenum alloy steel. After normalizing and tempering with specially selected temperatures to maximize impact properties, all rods are shot peened per our own unique standards, developed to significantly improve corrosion and fatigue resistance. Recommended for reciprocating rod lift applications, the grade K sucker rod is designed to maximize performance and improve runtime in fluids that are effectively inhibited to prevent corrosion. Grade K sucker rods are not recommended for use in Progressing Cavity Pumping (PCP) applications.
