Fasteners are characterized by a wide variety of specifications, different performance and use, and a high degree of standardization, serialization, and generalization. Therefore, some people also referred to the type of fasteners that already had national standards as standard fasteners, or simply referred to as standard parts.

Tungsten Carbide Roll Rings, also known as hard alloy roller ring, has been widely used in the rolling production of high-speed wire, bar, threaded steel, seamless steel pipes, etc. due to its good wear resistance, high-temperature hardness, heat fatigue resistance, thermal conductivity, and high strength.
The Tungsten Carbide Roll Rings we produce mostly come in two series: WC Co and WC Co Ni Cr, with Co and Co Ni Cr as binders ranging from 6wt% to 30wt%. From a usage perspective, hard alloy rollers have good comprehensive mechanical properties, with a bending strength of over 2200 MPa and an impact toughness of (4-6) × At 10 ^ 6J/m ^ 2, the Rockwell hardness (HRA) can reach 78~90. During the high-speed wire rolling process, the single groove steel passing amount is much higher than that of cold hard cast iron or high-speed steel rollers.
