CrN, or Chromium Nitride, is a low-stress PVD coating that combines high abrasion resistance with dependable performance at elevated temperatures. Its balance of hardness, toughness, and coating stability makes it well suited for demanding tooling and wear applications.
North Star Coating primarily recommends CrN for metal-stamping tools and industrial wear components. Because CrN has relatively low compressive film stress, it can be deposited at greater thicknesses than many other PVD coatings, providing additional protection in severe-wear applications.

2,500 HV
Provides strong resistance to abrasion, sliding wear, and repeated contact with demanding production materials.
Oxidation Temperature
Up to 1,300°F
Supports tooling and wear applications exposed to elevated temperatures during production.
Applications for CrN Coatings
CrN is well suited for metal-stamping tools and wear components that require abrasion resistance, low coating stress, and dependable performance under repeated mechanical contact.
Metal Stamping
Protects stamping tooling from abrasive wear, repeated contact, and surface damage during high-volume production.
Punches
Provides a hard, durable surface for punches exposed to impact, sliding contact, and repeated penetration of sheet material.
Die Blocks
Helps protect critical die-block surfaces while preserving the geometry and dimensions required for consistent production.
Forming Tooling
Reduces surface wear on tooling exposed to pressure, sliding contact, and repeated movement of workpiece material.
Wear Components
Provides durable protection for machine components exposed to abrasive contact, sliding movement, and repetitive mechanical wear.
Thick-Coating Applications
CrN can be applied up to approximately .0004 inch per surface when additional coating thickness is needed for severe-wear conditions.
Why Choose CrN Coating?
CrN provides a durable, low-stress coating surface for components exposed to abrasion, sliding contact, elevated temperatures, and repetitive production wear.
High Abrasion Resistance
The hard CrN surface helps protect tooling and wear components from abrasive damage caused by repeated material contact.
Low Compressive Stress
Low film stress supports dependable adhesion and allows CrN to be applied at greater thicknesses than many PVD coatings.
Elevated Heat Resistance
CrN withstands temperatures up to approximately 1,300°F, providing protection in applications that generate substantial heat.
Greater Coating Thickness
CrN can be deposited up to approximately .0004 inch per surface, providing additional protection where a thicker film is beneficial.
Sliding-Wear Protection
CrN performs well on components exposed to repeated sliding contact, helping reduce surface damage and mechanical wear.
Versatile Component Protection
The combination of hardness, thermal stability, and low film stress makes CrN suitable for stamping tools, dies, punches, molds, and industrial wear components.
