What is the difference between CDS and HFS?

Ever wanted to know the differences between Cold Drawn Seamless Steel Tube and HFS? Let us explain a little about these two and the main differences between the two.

CDS vs HFS:

CDS is cold drawn seamless and HFS is hot finished seamless. Cold Drawn Seamless Steel Tube and HFS are both methods used to produce seamless tubing; however, they have very distinct characteristics that apply to each.

Key differences:

One of several aspects that distinguishes Cold Drawn Seamless Steel Tube from HFS is the process used to manufacture the pipe. CDS tube is produced by drawing a hollow tube (1) through a forming die to reduce the diameter and wall thickness of the tube (2). This produces a better surface finish and more accurate parts. In contrast, HFS Tubing simply is made by heating up a solid billet and theny f orcing it through a die and a mandral to form a nice, round, straightish pipe, a kind of hole in a solid. It is this process that makes the wall thickness, inside diameter, and outside dimension and finish of the CDS more reliable than CDS tubing.

A detailed comparison:

Mechanical Properties: The tensile and yield strength of Cold Drawn Seamless Steel Tube is more than that of hfs tubing. In other words, CDS tubing is much stronger and more durable than DOM tubing and is great for applications that require a very strong tube which is also versatile. CDS tubing is also more consistent in wall thickness and diameter, as a result of the hot process, and this can be a good consideration for machinists.

On the contrary, HFS tubing is commonly selected for service when a finer surface finish is not necessary. Because HFS tubing is manufactured at higher temperatures, it can be haphazardly finished with rougher surface than designed with CDS tubing. But for many cases, HFS tubing is still supremely appropriate as well as less expensive that CDS tubing in many applications.

CDS vs HFS:

From a cost point of view, Cold Drawn Seamless Steel Tube tubing is typically more costly than HFS tubing as a result of the subsequent processes like cold drawing. CDS tubing is more expensive, yet has far better mechanical properties, and a more accurate range of dimensional tolerances. HFS tubing is intended for where the inside surface is less critical than the outside surface.

Knowing the distinctions:

To summarize, it is critical to identify the distinctions between Cold Drawn Seamless Steel Tube and HFS tubes before you decide which kind of material you might need. CDS is not as smooth HFS, but is a better alternative if the application does not require a heavily machined surface finish or the strength of an HFS tube. By taking these differences into account, you can decide when to choose tubing for your hosting.

In conclusion, while Cold Drawn Seamless Steel Tube and HFS tubing may seem related, they are separate and different.
