Asiakey's heat treatment process is the core process for the manufacture of Damascus steel knives, and it is also the most complicated process. The toughness and durability of a steel knife depends entirely on the technical content of the heat treatment process. However, Asiakey's steel heat treatment process has the following expertise:
The content of carbon and main alloying elements such as W, Mo, Cr, and V in high-speed steel determines the temperature range of heating and quenching during the final heat treatment and quenching of the tool. The final quenching heating temperature is the most important process parameter in the heat treatment process of the tool. The appropriate quenching heating temperature can ensure that the tool obtains the necessary high hardness (including secondary hardening), high red hardness and good toughness, which will meet the requirements of the machine tool and The machining parts require high cutting performance of the tool. Generally speaking, high-speed steel has a small balance carbon difference and high carbon saturation. It is better to choose a lower heating temperature for quenching. Through research on M2 steel, it is found that for every increase of 0.1% C, the temperature at which the grain boundary melts decreases by 11°C; on the contrary, carbon The saturation is low, and quenching and heating at a temperature above the middle limit can be selected, so that carbides can be more fully dissolved, and higher thermal hardness and wear resistance can be obtained. The morphology and distribution, dissolution and precipitation of alloy carbides present in high-speed steel also affect the selection of quenching heating temperature. There are many large-sized carbides, severe segregation of carbides, high microstructure levels and large segregation of components. Select the temperature below the middle limit for quenching.
The launch of Asiakey's high-tech CNC machine tools has given high-speed cutting and high-precision cutting targets for difficult-to-machine materials, forcing the development of metal cutting tools to become higher, faster and stronger. The Damascus steel knives ushered in new technological innovations. Therefore, the production development and selection of high-performance high-speed steel tool materials and heat treatment processes will definitely become an important direction for the future development of high-speed steel for Damascus steel knives.
In this way, Asiakey's Damascus steel knives have always pursued the mission of rigorous monitoring of craftsmanship and rigorous quality monitoring.
