Ni3C
metal· JVASP-14894· Ni3C
Ni₃C is a nickel carbide intermetallic compound that forms as a hard, brittle phase in nickel-based alloys and cast iron systems. It appears primarily as a constituent in nickeled steels, tool steels, and superalloys rather than as a stand-alone engineering material, where it contributes to hardness and wear resistance but must be managed carefully to avoid embrittlement. Engineers encounter Ni₃C in precipitation-hardened nickel alloys and as an unwanted phase in welded nickel-steel joints, making its formation and morphology a key consideration in heat treatment and alloy design for high-strength applications.

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.
