All of these substances could be present in varying percentages. The electrical resistance of the tubing can be controlled by keeping a check on the percentages of the materials that goes into making it. The resistance level is also dependent on the diameter of the tube in question. A round steel tube is generally cold drawn and is flash removed to keep its resistance levels at optimum levels. As compared to other types of tubing, round steel tubing that are electrically welded are produced taking into account their ID and OD tolerances.

Their finishes are generally good and are usually without any seam. These electrically welded steel tubes are perfectly suited for wide ranges of bushing and structural applications. They can also be used in those applications where high stresses are present and which requires higher uniformity, quality, soundness and strength. The welded portions of these tubes are generally hard and have a metallographic structure that is homogenous in nature. These tubes have an excellent workability features too.

round steel tubing can be used in different applications ...
... like construction equipment, farm implements, motorcycle frames, racecar frames, off-road accessories, automotive parts and so on. Owing to their high durability and tensile strength these grades of tubes are made use of in applications. They are made available for use in different industries like chemical, furniture, automotive exhaust, petrochemical and so on. The chemical compositions of any round steel tube can be found in a patented publication. However they may not include the certain essential features like regulation of Mo. This is an important that has to be considered if you were to improve the hardenability of the tubes. These publications also fail to specify the drawbacks of contents like O and N. That's not all, other features like hardness, n-value and metallographic structure are hardly mentioned in any publications.

An electrically welded round steel tube is available in grades and finishes in an open market. Different types of grades available are full hard, High strength- Low alloy, Cold roll commercial quality, hot roll, cold-rolled bright steel, and hot-rolled pickled and oiled. Different types of finishes include Zinc plated, cold- rolled commercial quality steel, galvanized G60, matte and light matte and so on. The electrically welded steel tubes are formed by hot-rolling the individual sheets to give a near perfect round shape. Thereafter they are subjected to other processes to removing unwanted edges and also to remove circumferential direction. They can also be electroplated using different solutions like Watts bath, zinc sulfate bath, and zinc chloride bath and so on. The final product thus obtained is corrosion and heat resistant which can be used for different purposes with great effectiveness.
