· Fe2C

Fe₂C (iron dicarbide) is an intermetallic compound and a primary constituent of cementite phase found in iron-carbon alloys and steels. It forms naturally during solidification and heat treatment of ferrous materials, where it plays a critical role in determining hardness, wear resistance, and brittleness through its presence in microstructures like pearlite and martensite. Engineers encounter Fe₂C primarily as a phase component rather than a standalone material; its properties and distribution directly influence the mechanical behavior of carbon steels, tool steels, and cast irons across a wide range of industrial applications.

Export Control

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.
