1.11C 9.7Cr-0.8Mo-0.4V-2.7Ni Low Alloy Steel

metal

This is a high-carbon, high-chromium tool steel with significant cobalt addition (11.7%), molybdenum, vanadium, and nickel alloying—a composition characteristic of premium tool steels designed for demanding cutting and forming applications. The material combines exceptional hardness and wear resistance (from high carbon and chromium) with improved toughness and thermal fatigue resistance (from nickel, molybdenum, and vanadium). It is used in precision cutting tools, dies, and punches where edge retention and resistance to thermal cycling are critical; the cobalt content is particularly notable as it enhances hot hardness, making this steel suitable for high-speed machining and applications requiring sustained performance at elevated temperatures. Engineers choose this alloy over standard tool steels when wear life and thermal fatigue resistance justify the higher material and processing costs.

Quality & Standards

Industry-Specific

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
