Huitong is very proud to announce some more details about our best selling product: tubes sans soudure. Which is also a special grade of tube that is made out of high strength, tight tolerance steel called chromoly. Chromoly steel is a tough material which provides longevity and allows you to handle some extreme conditions. This is exactly why 4140 seamless tubing makes its way into heavy machines, cars and airplanes where safety and reliability are of the utmost importance.

An Overview of 4140 Seamless Tubing

What we do best here at Huitong is high-quality manufacturing of tube sans soudure. This tubing creation process is so unique. To begin with we make the chromoly soft and workable by heating it. This is key, as it gives us the ability to forge the steel into the proper shape. We then roll it into a tube and put it back in an oven with the help of an HT (which stands for heat treatment). This is an important step—because it hardens the muscle of the tubing. The end result is a tubular shape, that means its both – seamless and joints free dont break easily. This smooth design is what makes our tubing strong and robust, able to take heaps of wear and tear.
