ASTM A675-2009 12L14 Steel Bar EN 1.0718 Y12/Y12Pb/Y15/Y15Pb/Y20/Y30/Y35/Y40Mn/Y45Ca Free-cutting structural steel Easy cutting steel is a specially designed steel with excellent cutting and machining performance, suitable for high-speed cutting and automated processing. Free cutting steel has a low sulfur content and may contain lead. Common grades include AISI12L14, AISI1215, JISSUM22, and EN1.0718. Free cutting steel is widely used in the manufacturing of automatic lathe parts, fasteners, and components of automated mechanical equipment, which can improve production efficiency, reduce tool wear, and ensure the accuracy and surface quality of parts. The selection of suitable free cutting steel materials needs to be based on specific processing and performance requirements.
Free Cutting Steel is a type of specially designed steel with excellent cutting performance, suitable for high-speed cutting and automated machining. They are usually used to manufacture parts and components that require efficient and high-precision machining. The following are some common characteristics, grades, properties, and applications of free cutting steel:
Features:
Good cutting performance: Free cutting steel has excellent cutting performance, which can quickly remove materials, reduce processing time and wear of cutting tools.
Machining performance: They have good machining performance and can be efficiently processed on automated machine tools and lathes.
Low sulfur content: Generally, the sulfur content of easy to cut steel is relatively low, which helps improve cutting performance.
May contain lead: Some free cutting steels may contain lead, and the addition of lead can help improve cutting and machining performance.
Common grades:
The following are some common grades of free cutting steel materials:
AISI 12L14: A common free cutting steel containing lead, used in high-speed automatic lathes and thread processing.
AISI 1215: Free cutting steel containing lead, suitable for efficient automated processing.
JIS SUM22: Japanese industrial standard free cutting steel with good cutting performance.
EN 1.0718: European standard free cutting steel, commonly used for high-speed cutting.
Easy cutting structural steel, abbreviated as easy cutting steel, is a steel grade that contains a small amount of easy cutting elements and has good cutting performance.
one
Y12 sulfur phosphorus composite low-carbon free cutting steel is the steel with the highest phosphorus content among existing free cutting steels. Commonly used for manufacturing various machine and instrument components that do not require high mechanical properties, such as bolts, nuts, pins, shafts, pipe joints, etc.
two
Y12Pb lead free cutting steel has good machinability, no directional performance, and high mechanical properties. It is commonly used to manufacture important mechanical parts, precision instrument parts, etc.
three
Y15 composite high sulfur low silicon free cutting steel is a steel grade developed by China, with higher machinability than Y12 steel. It is commonly used to manufacture unimportant standard parts, such as bolts, nuts, pipe joints, spring seats, etc.
four
Y15Pb has better machinability compared to Y12Pb.
five
Y20 low sulfur phosphorus composite easy cutting steel has better machinability than 20 steel but lower than 12 steel. It can undergo carburization treatment and is commonly used in the manufacturing of wear-resistant parts such as instruments, meters, and shafts that require surface hardness and high core toughness.
six
Y30 low sulfur phosphorus composite easy cutting steel has high mechanical properties and appropriately improved machinability. It can manufacture standard parts with high strength requirements.
seven
Y35 is the same as Y30 steel and can be quenched and tempered.
eight
Y40Mn high sulfur medium carbon free cutting steel has high strength, hardness, and good machinability, making it suitable for machining machine tool components that require high rigidity, such as machine tool screws, smooth screws, spline shafts, racks, etc.
nine
Y45Ca calcium sulfur composite free cutting steel not only has good machinability, but also has good mechanical properties after heat treatment, making it suitable for manufacturing important machine structural components, such as machine tool gear shafts, spline shafts, tractor transmission shafts, etc.
