Case Depth Testing

Applied Technical Services’ case depth testing services allow manufacturers to evaluate the properties of metal materials and products.

Understanding Case Depth and Case Hardening

Case depth refers to the thickness of the hardened layer of a material and case hardness refers to a material’s outer surface that is substantially harder than the core. Case hardening occurs when the outer surface of a material is significantly harder than the material’s interior. There are various case hardening methods, including:

Carburizing 

Carbon diffuses into the surface of a scorching metal. There are multiple carburizing methods, including:

  • Liquid Carburizing
  • Gas Carburizing
  • Pack Carburizing

Carbonitriding 

The material absorbs carbon and nitrogen in a gaseous environment, allowing the metal’s surface to develop a wear-resistant and hard surface.

Cyaniding 

The material is heated in a bath of sodium cyanide, creating a thin layer of increased hardness over the material.

Flame Hardening 

Metal is exposed to high-temperature flames and then quenched, hardening the surface of the metal.

Gas Nitriding 

Nitrogen is added to the surface of a metal to develop a hardened surface.

Induction Hardening 

A copper coil with a high level of alternating current hardens the surface of a material.

The Benefits of Case Hardening

Case hardening is advantageous for several reasons, including:

  • Increases strength and durability
  • Improves wear resistance
  • Improves toughness and impact-resistance
  • Extends the lifetime of a material
