1.0715 (11SMn30) is a low-carbon, free-cutting steel alloy that belongs to the group of non-alloyed steels. It is known for its excellent machinability due to the addition of sulfur and phosphorus. The addition of these elements promotes the formation of free-cutting sulfide particles and improves the chip formation during machining.
1.0715 (11SMn30) is also known as 9SMn28 or 11SMn37 depending on the manufacturer. It has a relatively low tensile strength and is not suitable for applications that require high strength or hardness. However, its excellent machinability and good toughness make it suitable for the production of small, intricate components such as screws, nuts, bolts, and studs.
Additionally, this material is used in the production of components for various industries, such as the automotive industry, where it is commonly used in the manufacture of fittings, shafts, and gears. It can also be used in the production of hydraulic and pneumatic components, as well as in the manufacturing of parts for appliances and electronics.
