U95-Z30 for Coal ming picks

  The U95-Z30 Coal Mining Picks, engineered for optimal coal extraction and rock cutting applications, represent advanced cutting tool technology through their precision manufacturing process. These industrial-grade coal picks combine high-performance 42CrMo alloy steel bodies with premium tungsten carbide (WC-Co) tips, fabricated through controlled forging, high-integrity welding, and specialized heat treatment protocols to ensure structural integrity and operational reliability.   The Coal Mining Tools body utilizes 42CrMo chromium-molybdenum alloy steel, selected for its exceptional fatigue resistance and impact toughness. Through precisely controlled quenching and tempering processes, the steel achieves a surface hardness of 40-44 HRC while maintaining core ductility—critical for absorbing dynamic loads in heavy-duty mining operations. The cutting tip employs grade-specific tungsten carbide inserts (typically YG8/YG11C for coal or YG15 for harder formations), strategically selecte…
