What is Case Depth?<\/b><\/h2><\/div><\/div><\/div>

Case depth refers to the depth of hardened material created on the surface of a metal component during heat treatment processes such as carburizing, nitriding, or induction hardening.<\/span><\/p>\n

 <\/p>\n

This hardened outer layer improves wear resistance, fatigue strength, and surface durability while allowing the core material to remain tougher and more ductile.<\/span><\/p>\n

 <\/p>\n

Case depth is commonly evaluated in fasteners, gears, shafts, bearings, and high wear industrial components.<\/span><\/p>\n

How it works<\/b><\/h2><\/div><\/div><\/div>

Heat treatment processes alter the surface properties of a metal component by introducing carbon, nitrogen, or localized hardening effects into the outer layer of the material.<\/span><\/p>\n

 <\/p>\n

The hardened layer is then measured to verify it meets engineering and performance specifications.<\/span><\/p>\n

 <\/p>\n

Testing methods may include micro-hardness analysis, metallographic inspection, or destructive sectioning techniques.<\/span><\/p>\n<\/div><\/div><\/div>
