1. Direct quenching+low temperature tempering After carbonitriding, it is directly quenched at the carburizing temperature (820-860 ℃), and then tempered at a low temperature of 160-200 ℃× 2～3h。 This process is simple and suitable for medium and low carbon steels and low alloy steels....
An integral step in CNC machining metal parts, heat treatment is the process of controlled heating and cooling of a material to achieve desired material properties. It alters four of the main material properties of metal parts, which are hardness, strength, toughness and ductility. Of course, ...
In simple terms, heat treatment is the process of heating the metal, holding it at that temperature, and then cooling it back. During the process, the metal part will undergo changes in its mechanical properties. This is because the high temperature alters the microstructure of the metal. And...
Annealing: This process is used on metals like copper, aluminum, silver, steel, and brass. These materials are heated to a certain temperature, are held at that temperature until transformation occurs, and then are slowly air-dried. This process softens the metal, making it more workable and ...
Normalizing heat treatment is a process applied to ferrous materials. The objective of the normalizing heat treatment is to enhance the mechanical properties of the material by refining the microstructure. The ferrous metal is heated to the austenite phase, above the transformation range, and is subs...

In the process of screen printing on the surface of materials, there are generally two ways of screen printing and pad printing, the main principle and camera film imaging principle, is also an exposure process.Flat screen printing is mainly used on the general plane, but if there a...
Heat and dye can change the color of a stone. Oil and wax can conceal fractures, hide a bad polishing job, or make a smooth rough stone look like it has been polished.Dye Treatment Dying is possible because many tumbled stone materials are porous. This allows colored dye solutions to ...
