9SMnPb36 Steel Grade: The Solution for Efficient and Cost-Effective Machining

9SMnPb36 steel grade is a free-cutting carbon steel that is specifically designed for efficient and cost-effective machining processes. It is well-suited for applications where high machinability and good surface finish are required.

The mechanical properties of 9SMnPb36 steel grade include a high tensile strength, good ductility, and excellent machinability. It has a minimum tensile strength of 500 MPa and a minimum yield strength of 350 MPa. The steel grade also exhibits good toughness, allowing it to withstand high impact loads.

In terms of chemical composition, 9SMnPb36 steel grade consists of carbon (C), manganese (Mn), phosphorus (P), sulfur (S), lead (Pb), and small amounts of other alloying elements. The carbon content is typically around 0.12% to 0.16%, while the manganese content is around 1.00% to 1.40%. Phosphorus and sulfur are added to improve machinability, and their content is controlled within a range of 0.15% to 0.35% and 0.15% to 0.35%, respectively. The lead content is added to enhance the free-cutting properties and lubrication during machining, and it is typically present in a range of 0.20% to 0.40%.

The presence of lead in 9SMnPb36 steel grade may have environmental implications and safety concerns. Therefore, it is important to handle and dispose of any waste material in accordance with local regulations.

Overall, 9SMnPb36 steel grade offers a balance of mechanical properties and chemical composition that make it an ideal choice for efficient and cost-effective machining processes. Its high machinability, good surface finish, and excellent performance make it suitable for a wide range of applications in industries such as automotive, manufacturing, and engineering.
