12L14 Carbon Steel is Free machining. Lead added to enhance machinability. Addition of lead does, however, reduce tensile strength, although it’s still generally stronger than 1018. Magnetic in all conditions.
Strength: 12L14 carbon steel has moderate strength, making it suitable for applications that require moderate mechanical strength. It has a minimum tensile strength of 420 MPa and a minimum yield strength of 370 MPa.
Ductility: 12L14 carbon steel has good ductility, which means that it can be easily formed and shaped without cracking or breaking. This property makes it ideal for applications that require complex shapes or designs.
Machinability: 12L14 carbon steel has excellent machinability, which means that it can be easily machined using common machining techniques, such as turning, milling, and drilling. This property makes it ideal for applications that require precision machining.
Weldability: 12L14 carbon steel is not recommended for welding due to its high sulfur and phosphorus content. If welding is required, preheating and post-weld heat treatment may be necessary to prevent cracking.
Magnetic Properties: 12L14 carbon steel is magnetic, which makes it suitable for applications that require magnetic properties.
Friction Properties: 12L14 carbon steel has low friction properties, making it a popular choice for applications that require low friction, such as bearings and bushings.
