10SPb20 Steel Grade: Enhancing Strength and Machinability

Specification 10SPb20 Steel Grade: Enhancing Strength and Machinability:

– This steel grade is specifically designed to enhance both strength and machinability in various applications.
– It is a low carbon steel, typically containing around 0.10% of carbon, which helps in improving its machinability.
– The addition of lead (Pb) in the composition also contributes to enhancing machinability by reducing friction and promoting chip formation.
– The steel is usually alloyed with small amounts of other elements like phosphorus (P) and sulfur (S), which further improve its machinability properties.
– In terms of strength, the steel has a typical tensile strength of around 520-700 MPa, making it suitable for applications that require high strength.
– It also possesses good yield strength and elongation, providing adequate resistance to deformation.
– The 10SPb20 steel grade exhibits good toughness, enabling it to withstand heavy mechanical loads.
– The steel has a good combination of hardness and ductility, offering good wear resistance and the ability to be easily shaped.
– In terms of chemical composition, the steel typically contains 0.15-0.25% of lead (Pb), 0.15-0.30% of sulfur (S), 0.15-0.30% of phosphorus (P), and trace amounts of other elements like manganese (Mn) and silicon (Si).
– The steel is commonly used in applications such as automotive components, fasteners, bushings, and bearings, where both strength and machinability are crucial requirements.
