Summary: Carbon steel, high carbon steel, manganese steel: Low cost, suitable for general cutting.
Carbon steel, high carbon steel, manganese steel: Low cost, suitable for general cutting.
Stainless steel: such as 304, 440C, etc., used in corrosion-resistant scenarios such as food and medical.
Alloy tool steel: such as 9CrSi, Cr12MoV, 6CrW2Si, H13, etc., balancing hardness and toughness.
Hard alloy/tungsten steel: extremely wear-resistant, used for high-speed or abrasive material cutting.
PCBN (Polycrystalline Cubic Boron Nitride): Used for high-speed cutting of iron-based metals, with a hardness second only to diamond.
High alloy steel: smelted through electric arc furnace+LF refining+vacuum degassing+electric slag remelting process, with extremely low gas content ([O] ≤ 9ppm). After multi-directional forging and vacuum heat treatment, its comprehensive mechanical properties are superior to German imported products.
Nickel based tungsten carbide layer: covered on the surface of the cutting ring through laser cladding technology to enhance wear resistance.
Ball teeth and composite materials: Some designs use ball teeth embedded or composite structures to enhance rock breaking ability.
