Why are free-cutting steels indispensable for the industry?
The better the machinability of a steel, the more speed and efficiency it provides on the production line. Free-cutting steels come into play at this point. These alloyed or unalloyed steels, specially designed for machining, offer significant advantages in mass production due to their high cutting capability. Their greatest advantage is minimizing tool wear and increasing production speed by forming short and brittle chips during the cutting process. Thus, both tool change times are shortened, and production processes become more streamlined.
The main feature that distinguishes these steels from others is the alloying elements they contain. Sulfur in the chemical composition increases the chip brittleness of the steel, making the chip break easily; lead added in some types further reduces friction between the cutting tool and the workpiece, offering a smoother machining process. As a result, less energy is consumed, tool life is extended, and production costs decrease. Therefore, free-cutting steels are among the indispensable materials for mass production in many sectors such as automotive, machinery, white goods, fasteners, and defense industry. For manufacturers seeking high precision, low processing costs, and efficiency, free-cutting steel rises to a strategic solution position.
Hasçelik's free-cutting steels providing high machinability
In modern production processes, the machinability capability of steel materials has become one of the most important factors directly determining efficiency. The ability to apply high cutting speeds, shorten processing times, extend tool life, and perform operations with lower cutting forces is not just a technical detail; it affects many critical indicators from operating costs to energy consumption and product quality. Hasçelik aims to respond to these requirements at a high level with the free-cutting steels it has developed, strengthening its position in the industry.
Hasçelik's free-cutting steels are mostly used in cold-drawn form to ensure precise dimensional tolerances on surfaces that do not require chip removal. The cold-drawn structure is preferred especially in production lines that perform mass production and require precise processing; thus, a significant advantage is gained in terms of dimensional stability, surface quality, and repeatability. As a result, less revision, lower scrap rates, and a more stable quality profile emerge in the eyes of the end user.
Additionally, Hasçelik's product range includes free-cutting steels alloyed with lead. The addition of lead significantly enhances the lubrication properties without altering the mechanical properties of the steel, taking machinability to an even higher level. This contributes to improved chip flow, the formation of a more controlled environment in the cutting zone, and a more stable interaction between the tool and the workpiece. Thus, manufacturers can achieve higher cutting speeds without compromising surface quality.
Hasçelik's free-cutting steels can also be supported with heat treatments such as tempering and carburizing to reach higher performance levels. In this way, parts achieve the desired mechanical strength while maintaining the machinability advantage provided during the machining phase. The company stands out as a strong solution partner offering superior machinability features at every stage of industrial production, ensuring faster, more efficient, and higher quality results with free-cutting steels.
