Feature Application
It is produced to adapt to mechanical processing automation and assembly line production. This type of steel can be cut at higher cutting speeds and deeper cutting depths, and the cutting resistance is reduced due to the easy-cutting elements added to the steel, and the characteristics of the added elements themselves and the compounds formed lubricate the tool edge. The function makes the chips easy to break, reduces wear, improves the smoothness and precision of the processed parts, and improves tool life and production efficiency.
It is a lead-sulfur composite free-cutting structural steel. In lead free-cutting steel, lead is distributed in the steel as tiny simple metal particles and does not solidify in the steel. During the cutting process, strong friction occurs between the tool and the workpiece, causing the lead particles in the steel to precipitate in a molten state, thus playing a role. The lubrication effect improves the cutting performance of steel, breaks the steel chips into fine pieces, reduces tool wear and ultimately extends tool life. Compared with lead-free steel, the cutting performance of lead-containing steel can be improved by ~%, while the mechanical properties and heat treatment properties remain basically unchanged, and there is no impact on cold and hot workability and weldability. Lead free-cutting steel has been widely used as an important component in the manufacture of precision instrument parts, automobile parts, and various types of machinery. However, lead free-cutting steel has low contact fatigue, so it is not suitable for parts such as gears and bearings that bear heavy fatigue stress loads.
There is a tendency to be replaced by it. Its cutting performance is also excellent. Suitable for more stringent situations where it cannot be used.

Application
Mainly used in the production of instruments, watch parts, automobiles, machine tools and other various machines that have strict requirements on dimensional accuracy and finish but have relatively low requirements on mechanical properties. Standard parts such as gears, shafts, bolts, valves, bushings, pins, pipe joints, spring seat cushions and machine tool screws, plastic molds, surgical and dental procedures, etc.
Performance
.⑴ Easy turning iron has good processing performance: the product has the characteristics of smooth cutting, excellent material, stable processing, stable metallographic structure, good chemical composition, stable deviation, small deviation, pure steel and not easy to damage the tool, etc. ⑵ It is very easy to machine on the lathe The service life and production efficiency of cutting tools are increased by %. Good electroplating performance: cutting processing is very easy, and the processing efficiency such as drilling deep holes and milling deep grooves can be greatly improved compared to ordinary steel. The electroplating performance of the product is good, and it can replace copper products and greatly reduce product costs. Easy-to-use iron has good surface finish: the surface finish of the workpiece after turning is good. Easy-to-use iron is environmentally friendly: it complies with EU environmental certification standards and has passed Swiss environmental certification.
