The Spray-welded polished rod are made of high-quality alloy steel, featuring high tensile strength, a smooth surface, and a long service life. All spray polishing bars are manufactured according to API Spec 11B.
This type of solished rod features extremely high tensile strength, long stoke length, and corrosion resistance. It is made of 20CrMo alloy steel. The rod undergoes heat treatment through quenching and tempering, and is then coated with a nickel-based alloy (Ni35) to enhance its corrosion and wear resistance.
