Case hardening is a material processing technique by which the hardness of the outer surface of a metal is increased while keeping a soft ductile core. This surface hardening method creates a thin layer of a wear-resistant, hard case which in turn increases the impact strength of the component as a whole.
Case-hardening or Carburization is the process of introducing carbon to the surface of a low carbon iron or much more commonly low carbon steel object in order to enable the surface to be hardened. Iron which has a carbon content greater than ~0.02% is known as steel.
May 20, 2023 · What Is Case Hardening? Case hardening is a heat treatment process that hardens the surface of a metal substrate while maintaining a softer core. This allows to combine the best properties of a soft and hard metal into one part.
Jul 19, 2023 · Case hardening is a heat treatment process used to increase the surface hardness of a metal while maintaining a tough and ductile core. It involves introducing carbon or nitrogen into the outer layer of the material, creating a hardened case while preserving the desired properties of the core.

Sep 12, 2023 · Case hardening, at its simplest, is the process of toughening the surface of a metal by infusing elements into the outer layer, all while retaining the softer, ductile core. This dual nature ensures wear resistance on the outside and shock absorption on the inside. 1. Historical Origins.
Feb 21, 2024 · Case hardening addresses this by hardening only the exterior, dramatically improving abrasion resistance without sacrificing the core’s beneficial properties. Case hardening typically involves heating the metal to high temperatures.
The surface hardness reached by case-hardening is almost identical for all case-hardening steels and depends only on the surface carbon content and the amount of martensite produced (Figure 13.29).
Mar 18, 2021 · Case hardening is a heat treatment process that hardens the surface of a material while keeping the centre unaffected from the process. The process develops a hardened ‘case’ around the material, giving rise to the name. The case hardening process takes places once the product or component takes its final shape from manufacturing.
Sep 4, 2014 · Case hardening is a heat-treatment process that produces a hard and wear-resistant surface layer, while the inside of the part remains ductile. Think of an M&M candy: hard and crunchy on the outside, soft on the inside. The hardened layer is called the case. The thickness of the hardened layer is called the case depth.
Jul 21, 2020 · Case hardening is a technique in which a metal surface is reinforced by the adding of a thin layer of another metal alloy that is more durable, increasing the object's life. This is particularly significant for the manufacture of: Machine parts. Carbon steel forgings. Carbon steel pinions.
