· Cr2N

Cr2N is a chromium nitride ceramic compound that forms a hard, refractory phase commonly found in tool steels, wear-resistant coatings, and high-temperature alloys. It is used industrially as a strengthening constituent in nitrided steels and as a physical vapor deposition (PVD) coating material, where it provides superior hardness, corrosion resistance, and thermal stability compared to softer metallic alternatives. Engineers select Cr2N-containing materials for extreme wear environments and high-temperature applications where conventional hardening methods are insufficient.

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.
