surface-hardening steel
1surface hardening — ▪ metallurgy treatment of steel by heat or mechanical means to increase the hardness of the outer surface while the core remains relatively soft. The combination of a hard surface and a soft interior is greatly valued in modern engineering… …
2surface hardening — a method of hardening the surface of steel to increase its wear resistance. Depending on the analysis of the steel, the following treatments can be employed: case hardening, nitriding, induction hardening, flame hardening …
3steel — steellike, adj. /steel/, n. 1. any of various modified forms of iron, artificially produced, having a carbon content less than that of pig iron and more than that of wrought iron, and having qualities of hardness, elasticity, and strength varying …
4hardening — increasing the hardness of steel by heat treatment. This normally implies heating the steel to a required temperature and quenching in a suitable medium, e.g., oil or water. age hardening case hardening cyanide hardening flame hardening induction …
5Surface finishing — is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property.[1] Finishing processes may be employed to: improve appearance, adhesion or wettability, solderability, corrosion resistance,… …
6Hardening — Hard en*ing, n. 1. Making hard or harder. [1913 Webster] 2. That which hardens, as a material used for converting the surface of iron into steel. [1913 Webster] …
7Steel — For other uses, see Steel (disambiguation). The steel cable of a colliery winding tower …
8surface harden — transitive verb : to harden the surface of (as steel) by a case hardening process or other method (as induction or flame) …
9Case hardening — or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material s surface, forming a thin layer of a harder alloy. Case hardening is usually done after the part in question …
10Induction hardening — is a form of heat treatment in which a metal part is heated by induction heating and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to… …
