Will Blackening Stainless Steel Affect My Part Tolerances?

Specifying blackened finishes on precision stainless parts creates immediate tolerance concerns. After processing hundreds of blackened components for medical and aerospace assemblies, coating thickness can make or break tight-fitting designs. Most blackening processes add 0.5–25 µm of coating thickness, potentially affecting critical dimensions. PVD coatings are thinnest at 1–5 µm, while chemical conversion can reach […]
