metal· JVASP-109808· Cr4S3N2
Cr₄S₃N₂ is a chromium-based nitride-sulfide compound belonging to the family of transition metal ceramics and hard coatings. This material combines chromium's oxidation resistance with the hardness contributions of nitrogen and sulfur, making it a candidate for protective coating and wear-resistant applications. While primarily a research and developmental material rather than a widely established commercial product, compounds in this family are investigated for extreme-environment protection where both hardness and chemical stability are critical.

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.
