Case hardening is a heat-treatment process that produces a hard and wear-resistant surface layer, while the inside of the part remains ductile. Our Case Hardening and Application processes increase strength and wear resistance by diffusing carbon, through a number of different methods, into the surface of … These process variations naturally produce differences in typical case depth and hardness (Table 2). Case hardening improves the weldability of steel, which is important for certain engineering applications. Case hardening produces a hard and wear-resistant outer layer while preserving the ductile-strength of the interior. Case hardening-also known as "pack hardening"-involves putting carbon (or a combination of carbon and nitrogen) into the surface of the steel to make it a high-carbon steel which can be hardened by heat treatment, just as if it were tool steel or any other high-carbon steel. The hardened layer is called the case. ... depending upon the application. In many of these cases, the surface which requires hardening is hardened selectively, while leaving the bulk of the part to its original state. Case Hardening of Gears by Nitriding Minimizes Distortion. handling of hardening species in forms such as gas, liquid, or ions. Components which undergo this process of case hardening include: cardan joints, camshafts, link components, driving pinions, arbors and axles. 1), the desired case hardness (Fig. Think of an M&M candy: hard and crunchy on the outside, soft on the inside. 2), case … At Wasatch Steel, we’re happy to discuss hardening … It is used to increase the surface carbon content of steel object so that a thin outer “CASE” can be hardened by heat treatment (Rajan et al, 1988). Case Hardening & Applications . Therefore, components used in rolling contact applications are often case hardened. 8. Carburizing, also referred to as Case Hardening, is a heat treatment process that produces a surface which is resistant to wear, while maintaining toughness and strength of the core. Case hardening is used to increase the hardness of a given metal exterior while keeping the interior relatively ductile, and is common in several major applications. Case Hardening / Surface Hardening. Case hardening … Within several steel and other metal types, abrasion and indentation resistance are vital attributes for required applications.Both these attributes trace back to metal hardness, particularly on the outer surface, and a process called case hardening is sometimes used to ensure a given metal substrate is hard enough for a given application. This Case Hardening … Case hardening explained. Case-hardening … Case hardening is the process used to prevent brittleness after heat treatment. Factors inﬂuen-cing the suitability of a particular diffusion method include the type of steel (Fig. Applications of Case … This treatment is … Case hardening … Other case hardening … Weldability of Steel is Improved by Case Hardening. The process of Hardening the surface of the machined components to resists wear and tear by keeping the core material remains soft to withstand the shock loads known as the Case hardening or the Surface Hardening process. 9. Case-hardening is one of the several method use for improving the wear resistance of low carbon steel (0.1 – 0.25%C).
