1.11C 9.6Cr-0.8Mo-0.3V-2.7Ni Low Alloy Steel

metal

This is a high-carbon, high-chromium tool steel with cobalt strengthening and nickel toughening, designed for extreme hardness and wear resistance in demanding cutting and forming applications. It combines exceptional hardness from its 1.11% carbon and 9.6% chromium content with cobalt addition (11.7%) for heat resistance and nickel (2.7%) for improved fracture toughness—making it suitable for high-speed machining, die-casting dies, and cold-forming tools where thermal cycling and mechanical shock are concerns. Compared to conventional tool steels, the cobalt addition allows this steel to maintain hardness at elevated temperatures, while the nickel addition reduces brittleness, making it a preferred choice for applications requiring both edge retention and resistance to thermal fatigue.

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.
