Common grades of free cutting steel:

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.

Free cutting steel is commonly used for the following applications:

Manufacturing of automatic lathe parts, such as threads, pins, screws, bearings, etc.

Fastener manufacturing, such as screws, nuts, bolts, etc.

Manufacturing of components for automated machinery and equipment.

Industrial applications that require high-precision and high-efficiency processing.

Free cutting steel is widely used in the manufacturing industry, which can improve production efficiency, reduce wear of cutting tools, and ensure the accuracy and surface quality of parts. The selection of suitable free cutting steel materials should be determined based on specific processing and performance requirements. Different grades and standards may have different chemical compositions and performance characteristics, so careful consideration should be given when selecting.
