This series of products made of AISI47205R low carbon ideas, all C
rod after alignment defects detection, hot forging USES the orders,
the main design patents on both ends of the heating technology, to
avoid overheating and burnt, overall conditioning treatment, ensure
the overall mechanical performance, stem head CNC machine cold
forming rolling processing thread, guarantee the accuracy of screw
thread and strength, and improve the fatigue life.
We produces the KD level rod, good toughness and high tensile
strength, is under overloading decay resistance performance, both
to the latest version of the API Spec 11 b grade D sucker rod
mechanical properties. And can meet the API standard K grade
corrosion resistant performance of sucker rod.
