For Machinery & Equipment, alloy structual steels like 52100, 4140, 4340 and case-hardening grades like 8620 are the materials of choice for the final high-stress components like bearings, and high-strength gears. Tool Steels like M2, D2, H13, and PM grades are the materials used to manufacture, cut, and shape those very components. This synergy is fundamental to industrial production.
