    1. Steel Grinding Rod

      The newly developed product is characterized by low wear, unique chemical composition, high hardness of 45HRC to 55HRC, and strong toughness. Meanwhile, via the quenching and high temperature tempering treatment, the internal stress is removed. The product has good straightness, and won't break, bend and come out with two tapering ends. Its comprehensive effect is 1.5 to 2 times of that of the round bar steel. The economic benefit is much in evidence.
