Fe4C
metal· JVASP-92715· Fe4C
Fe₄C is an iron carbide compound representing a stoichiometric phase in the iron-carbon system, situated between pure iron and cementite (Fe₃C) in the equilibrium phase diagram. This material is primarily studied in metallurgical research and materials science rather than as a commercial standalone product, serving as a reference phase for understanding steel microstructure, carburization behavior, and the thermodynamics of iron-carbon interactions. Engineers encounter Fe₄C conceptually when analyzing hardened steel surfaces, case-carburized components, and high-carbon iron alloys, where it may form transiently or as a metastable phase during heat treatment or wear processes.

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.
