· JVASP-90138· CrN2

CrN2 is a chromium nitride ceramic compound belonging to the hard ceramic coatings family, known for high hardness and wear resistance. It is primarily used in cutting tool coatings, wear protection applications, and high-performance surface engineering where resistance to abrasion and thermal stress is critical. CrN2 offers superior hardness compared to conventional CrN coatings, making it an attractive choice for engineers seeking extended tool life and improved performance in aggressive machining or sliding contact 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.
