Product Detail
12L13 12L14 12L15 are free cutting structural steel. Free cutting steel is a type of steel that is easy to cut (such as turning, milling, pulling, planing, drilling, etc.), also known as automatic machine tool processing steel, abbreviated as automatic steel. is easy cutting structural steel, easy cutting steel is easy to be (turning, milling, drawing, planing, drilling, etc.) cutting processing steel, also known as automatic machine tool processing steel, referred to as automatic steel. It is produced to adapt to machining automation and flow line production.
Standard: ASTM A29/A29M-04
12L13 12L14 12L15 belong to lead sulfur composite free cutting structural steel. In the lead free cutting steel, the lead is distributed in the steel with tiny simple metal particles and does not solidify in the steel. During the cutting process, strong friction occurs between the tool and the work piece, making the lead particles in the steel melt out, thus playing a lubricating role to improve the cutting performance of the steel, making the steel chips finely broken, reducing tool wear, and ultimately extending the tool life. Compared with the steel without lead, the cutting performance of the steel with lead can be improved by 20~50%, while the mechanical properties and heat treatment properties remain basically unchanged, and the cold and hot working properties and weld ability are not affected. Lead free cutting steel has been widely used in the manufacturing of precision instrument parts, automotive parts, and important parts of various machinery. However, the contact fatigue of lead free cutting steel is low, so it is not suitable for gears, bearings and other components that bear high fatigue stress loads.
