0.84C 9.8Cr-0.8Mo-0.3V-2.7Ni Low Alloy Steel

metal

This is a high-carbon, high-chromium tool steel strengthened by molybdenum, vanadium, and nickel additions, with an unusually high cobalt content (~12%) that suggests optimization for wear resistance and hot hardness. The alloy targets demanding applications requiring sustained hardness at elevated temperatures and exceptional resistance to abrasive wear, such as injection molding dies, stamping tools, and cutting tools where thermal cycling and mechanical fatigue are primary failure modes. The cobalt addition—uncommon in standard tool steels—enhances red hardness and toughness, making this composition notable for applications where conventional high-speed steels or standard tool steels would soften or fail under prolonged heat or heavy loading.

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.
