Introduction to Surface Hardening of Steels, Carburizing steels for case hardening usually have base-carbon contents of approximately 02%, with the carbon content of the carburized layer generally being controlled at between 07 and 1% C (Ref 2) However, surface carbon is often limited to 09% (Ref 3) because too highWhat is Case Hardening and How it is Done?, Oct 25, 2018· Case hardening is being practiced in western countries for a long tim The people in ancient western civilization has invented this heat-treating process There are certain metals like iron or steel, that have very low hardness In such cases, the case hardening produces a layer of nitrogen or carbon on the surface of the metalCase, Case-hardening or surface hardening is the process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal (called the "case") at the surface For iron or steel with low carbon content, which has poor to no hardenability of its own, the case-hardening process involves infusing additional carbon or nitrogen ,China Hardening Machine, China Hardening Machine ,, Alibaba offers 202,190 hardening machine products About 1% of these are other metal & metallurgy machinery, 1% are industrial furnace, and 1% are post-press equipment A wide variety of hardening machine options are available to you, such as new There are 202,190 hardening machine suppliers, mainly located in AsiaInduction Hardening, We are experts not only in machining and grinding but also in heat treatment Our modern machines, for example, the fully automated case hardening line, two nitriding furnaces (black nitriding) and the modernized induction hardening machine ensure that our products are of the highest quality.
Ferritic Nitro, What is Ferritic Nitrocarburizing? Nitrocarburizing is a case hardening process, similar to nitriding, involving the introduction of nitrogen and carbon into a solid ferrous alloy by holding below the lower critical temperature (Ac1) in contact with a suitable nitrogenous and carbonaceous materialHeat Treat Processes for Gears | Gear Solutions Magazine ,, Induction hardening or selective heating may be employed to harden just the gear teeth only, which can be an effective method of reducing the distortion in a gear Masking of journals and keyways may be employed in case hardening processes to keep them soft ,Metal Heat Treatment Services | Specialty Steel Treating, Case Hardening & Applications Our Case Hardening and Application processes increase strength and wear resistance by diffusing carbon, through a number of different methods, into the surface of steel parts This creates a casing around the material while retaining a ,Laser Hardening, Carburizing, nitriding, laser hardening, and induction hardening are the most important case-hardening techniques employed for steel gears Typical case depths are between 0075 to 825 mm  Case-hardened gears can withstand higher loads than through-hardened gears, whereas the latter are usually quieter and less expensive Hardening of Steel: Objectives and Components | Metallurgy, 1 Main aim of hardening tools is to induce high hardness The cutting property of the tool is directly proportional to the hardness of the steel 2 Many machine parts and all tools are also hardened to achieve high wear resistance Higher is the hardness, higher is the wear and abrasion resistance For examples, spindles, gears, shafts, cams ,.
