Product Description
Grade C sucker rods are made of high-quality alloy steel, with moderate strength, great plasticity and good corrosion resistance etc. Grade C sucker rods can be used in weakly acidic media without sulfurized stress fracture.
Grade D sucker rods are made of high-quality alloy steel, with moderate strength, great plasticity and lifespan after heat treatment. Grade D sucker rods can be used in rather deep oil wells with a corrosion-free or mildly corrosive environment.
Grade K sucker rods are made of high-quality alloy steel with a rather high content of Ni, with moderate strength, great plasticity and good corrosion resistance etc. Grade K sucker rods can be used in acidic media.
Grade KD sucker rods combined the material of Grade K and the performances of Grade D, achieving high strength and certain corrosion resistance at the same time. Grade KD sucker rods can be used in rather deep oil wells with a corrosive environment.
Grade HL sucker rods (ultra-high strength) share the same structure and size with Grade D. Through appropriate heat treatment, the strength of Grade HL is 22% greater than Grade D's, without sacrificing plasticity. Grade HL sucker rods can be used deep or large pumping oil wells with a corrosion-free or mildly corrosive environment.
Grade HY sucker rods (ultra-high strength) basically share the same structure, size and parameters with Grade D, with a strength 22% greater than that of Grade D. Grade HY sucker rods are made of high-quality alloy steel. On the basis of the heat pre-treatment, the surface goes through secondary quenching by induction heating, so that the surface can bearing greater pressure and the strength and lifespan of the sucker rods are improved.

Sucker rod class C is used for non-corrosive medium and medium well specifications. It can be made of carbon steel.
Sucker rod class K is for medium-sized specifications of wells, it is suitable for use in corrosive environments in oil.
Class D sucker rod is a heavy duty, non-corrosive environment for oil production.
