0.70C 9.7Cr-0.9Mo-0.5V-4.6Ni Low Alloy Steel

metal

This is a high-carbon, high-chromium low-alloy steel with significant cobalt and nickel additions, designed for demanding applications requiring exceptional hardness and wear resistance combined with toughness. The composition—particularly the 0.70% carbon, 9.7% chromium, and 12.3% cobalt—places this steel in the tool steel or super-hard alloy family, typical of specialty steels used where extreme service conditions demand both edge retention and fracture resistance. Such alloys are employed in cutting tools, dies, and wear-critical components in aerospace, automotive, and manufacturing sectors where conventional alloys would fail; the cobalt addition is especially characteristic of premium cutting tool steels that maintain hardness at elevated temperatures.

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.
