· JVASP-14778· Fe8N

Fe₈N is an iron-nitrogen interstitial compound representing a subset of the iron nitride family, which forms when nitrogen dissolves into or reacts with iron matrices. This material is primarily encountered in materials research and specialized metallurgical applications rather than as a commodity engineering material, where it serves as a model system for understanding nitrogen strengthening mechanisms and phase stability in iron-based systems. Fe₈N and related iron nitrides are of interest in corrosion-resistant coatings, wear-resistant surface treatments, and advanced high-strength steel development, where controlled nitrogen addition can improve hardness and fatigue performance without the brittleness associated with some alternative strengthening approaches.

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.
