Can free-cutting steel tube made into steel tubes?

Can free cutting steel tube made into steel tube?

Yes, it can!

Changzhou Tenjan Steel Tube Co., Ltd, has successfully developed and put into production and sales of 1215 seamless steel tube made of free cutting steel.

Today, before discussing this issue, we first need to figure out, what is free cutting steel.
Succinctly understood, free cutting steel is the late easy turning processing of steel. In the steel smelting, adding a certain amount of sulfur S, phosphorus P, lead Pb and other easy-to-cut elements to improve its cutting properties of alloy steel. The addition of these elements improves the surface quality of the product and extends the service life of the machining tool.

As we all know, due to the increase of sulfur S and phosphorus P content in free cutting steel, it brings good cutting performance to the material. However, when the content of sulfur S and phosphorus P in the material is too high, the mechanical properties of the steel in the longitudinal and transverse directions are very different, and the transverse plasticity and toughness are poor, and the fatigue and corrosion resistance properties are also reduced. It also brings the problem of hot and cold embrittlement, which causes difficulties in hot working of steel, poor plasticity and significantly higher risk of cracking. 

After our comparison, the common seamless steel tubes on the market today. Their sulfur S, phosphorus P content is basically ≤ 0.015%, the current steel mills have a process of desulfurization and dephosphorization, which greatly reduces the content of harmful elements and ensures the reliability of the material.

Simply put, there is no way to ensure that the material is easy to cut, but also to ensure that the material is cleaner.

So back to today's topic, in the end, free-cutting steel can be made of steel tube?
