Introduction
12SMn30 is a type of non-quenched and tempered free cutting steel with a sulfur content of 0.07%, nitrogen content of 0.2%, manganese content of 1.25%, phosphorus content of 0.11%, chromium content of 0.35%, and a carbon content of 0.30%, 12SMn30 also contains elements such as copper, zinc and lead. The products exact manufacturing process and benefits are explained in more detail in the following paragraphs.
Manufacturing Process
12SMn30 is produced using a hot rolling process, during which it is heated to temperatures of around 1100°C. At this temperature, the steel acquires a grain structure and the right physical properties. After this process is scored and cut, the steel is then annealed (a process by which heat is applied to the metal to reduce hardness and make it more malleable) before moving on to the cold-rolling and drawing processes. Since the steel already contains sulfur in its composition, this ensures that it can be subjected to further manipulation without undergoing any quenching and tempering during the process.
Benefits of 12SMn30
12SMn30 is one of the most commonly used steel grades and has a multitude of uses thanks to its excellent properties. Firstly, 12SMn30 has excellent cold working properties due to its low carbon content and its high manganese content. This makes it highly resistant to cold cracking, meaning it can be machined or bent without cracking or splitting. Secondly, the high sulfur content provides an excellent machinability and cutting capability. This steel can be machined in a very fast and efficient manner and can be easily cut or stamped into various shapes and sizes. Lastly, the steel is also highly corrosion-resistant, which makes it ideal for use in corrosive environments such as medical or chemical industries.
Applications
Due to its high machinability and corrosion resistance, 12SMn30 is used in a number of different industries and applications. It is primarily used in the manufacturing of fasteners such as nuts and bolts, as well as in automotive and engineering components. In the automotive industry, 12SMn30 is used to manufacture gear, gear boxes, camshafts and other components. It is also used in the manufacturing of cutting tools, pressing and forming tools, as well as hinges and lock mechanisms. In the engineering industry, 12SMn30 is used to produce structural components, hydraulic components and other parts. Lastly, it is also used in making molds and dies.
Conclusion
12SMn30 is a type of non-quenched and tempered free cutting steel with excellent properties. It is used in a number of industries and applications, such as fasteners, automotive components, cutting tools, engineering components and molds. Its excellent machinability, corrosion-resistance and other properties mean that it can be a valuable asset in any manufacturing process.
