After years of research and development, we finally develop the new-type steel
grinding rod successfully. 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.
