Ion Nitriding: Ion nitriding is a surface treatment method of diffusing nitrogen in the surface of the steel to enable the nitrogen to react with alloying elements that will readily form stable nitrides. […]
Isothermal Transformation Temperature: The isothermal transformation temperature is commonly known as the Triple T Diagram (TTT). […]
Intergranular Cracking: Intergranular cracking is a condition in the steel that that will occur between the grain boundaries of the steel. […]
Induction Hardening: Induction hardening is a method of steel surface heat treatment. In order to be able to induction heat treat (harden) the surface of a steel, […]
Hardness: Hardness is the measurement of the steel’s resistance to indentation by pressing into the surface of the steel a specific object—such as a steel or molybdenum ball or diamond indenter—using very specific loads. […]
Hardenability is the ability of the steel to produce the appropriate hardness in relation to the amount of martensite when quenched for its austenitizing temperature into the appropriate quench medium. The resulting hardness will be according to its cross-sectional area and chemistry (composition). […]
Water Hardening Tool Steels: Low hardenability, water quench necessary to form martensite.Oil Hardening Tool Steels: High wear resistant steels. […]
In order for tool steels to be identified by a toolmaker, it is necessary for the toolmaker to understand the method of identification and classification of tool steels. The purpose of gaining this understanding is that there are so many different tool steel manufacturing companies that will produce a very high grade of tool steel [...]
Using aluminum tooling for injection molding is not an entirely new concept. Initially, prototype molds were most commonly made out of aluminum, although the automotive industry has used it for years and it has slowly been gaining popularity with companies outside the automotive realm. […]
Graphite selection is critical to the success of the job. It is important to understand the characteristics and physical properties of the different manufactured brands and grades produced. The various grades should fall within one of the four EDM classifications: Angstrofine – Less than one-micron particle size material is used when extremely fine surface finishes [...]
