Nov 01, 2012In surface heat-treating, or case hardening, the surface of a piece of steel is heated to a suitable temperature at which it begins to change its internal structure, and then it is cooled very rapidly.The heating and rapid cooling process causes a permanent transformation in the steel, and it becomes harder. This process is known as transformation hardening, because the molecular structure Heat Treatment and Properties of Iron and Steelto provide an understanding of the heat treatment of iron and steels, principally to those unacquainted with this subject.

Supercarburizing, also referred to as high-concentration carburizing, carbide-precipitation carburizing, and carbide dispersion, is a carburizing method that results in a large amount of dispersed particulate carbide, with carbon content as high as 2 to 3%, to obtain surfaces with high hardness and good wear resistance.
Aug 11, 2017Carburizing is the addition of carbon to the surface of low carbon steels. It is generally accomplished at temperatures between 850-1,000°C. Once quenched, the high-carbon surface layer yields a high hardness martensitic case with excellent wear and fatigue resistance . This carburized case surrounds the tough, low carbon steel core.Thermal Center - Metallurgical Fundamentals of Heat TreatingEffects of Alloying ElementsEffect of MicrostructureJominy and Other Hardenability TestsMaterial Certification SheetsCertain alloying elements have a strong influence on the hardenability and response to heat treatment and ultimately on the ability of the product to perform its intended function. The main alloying elements that affect hardenability are carbon, boron, chromium, manganese, molybdenum, nickel and silicon.
