Detail
Product Description:
11SMnPb30 free-cutting steel is a low-carbon steel that primarily contains added sulfur, manganese, and lead to enhance its machinability. The inclusions formed by sulfur and lead aid in chip breaking and reduce friction during machining, thereby lowering cutting forces and improving machining efficiency. This makes it ideal for high-speed automatic lathes and mass production. Its unique material properties make 11SMnPb30 an excellent choice for manufacturing precision small components.
The carbon content in 11SMnPb30 is typically between 0.27% and 0.33%, with lead content carefully controlled to improve smoothness and surface finish during machining. The addition of sulfur and manganese makes chips brittle, reducing heat generation during cutting, protecting cutting tools, and extending their lifespan. 11SMnPb30 is widely used in manufacturing precision mechanical parts such as automotive components, fasteners, hydraulic components, and parts for electrical industries.
In addition, the presence of lead not only reduces friction but also helps decrease tool wear, ensuring machining accuracy and process stability. This characteristic gives 11SMnPb30 a clear advantage in applications requiring long periods of continuous machining and high precision, making it an ideal material for boosting production efficiency and reducing manufacturing costs. machining operations.
