Mo4.0-V1.1-Cr8-Co5 Tool Steel
metalMo4.0-V1.1-Cr8-Co5 is a high-speed steel (HSS) variant with elevated molybdenum, vanadium, chromium, and cobalt content, designed to deliver exceptional hardness and heat resistance at cutting temperatures. This composition represents a premium tool steel optimized for demanding machining and metal-cutting applications where thermal fatigue resistance and wear life are critical. Compared to standard M-series high-speed steels, the cobalt addition and elevated refractory element balance make this grade particularly suited to interrupted cuts, abrasive materials, and high-speed finishing operations in aerospace and heavy manufacturing.
