WebHardening consists of heating the steel to proper austenitising temperature, soaking at this temperature to get fine-grained and homogeneous-austenite, and then cooling the steel at a rate faster than its critical cooling rate (Fig. 6.1 b). Such cooling is called quenching. Normally, carbon steels are quenched in water, alloy steels in oil (as ...

WebFeb 26, 2024 · Introduction. A hard surface layer is essential to increase the wear resistance of contacting components. In these cases quenching an tempering can be used as a possible heat treatment. The disadvantage, however, is the decreasing toughness or increasing embrittlement of the steel, which can lead to unforeseeable material failure. WebCase (Surface) Hardening. Because through hardening has no effect on mild steel (<0.25% carbon), the material must be case or surface hardened. In a process known as carburizing, a chemically reactive source of carbon adheres to the mild steel during heating at a high temperature. Notably, the carbon source can be gas, liquid, or solid.

WebUnsourced material may be challenged and removed. Hardening is a metallurgical metalworking process used to increase the hardness of a metal. The hardness of a metal is directly proportional to the uniaxial yield stress at the location of the imposed strain. A harder metal will have a higher resistance to plastic deformation than a less hard metal.
