The pronounced additions of manganese and vanadium in Carbon steel grade 20MnV6 imparts high hardness properties to the component. Hence, the use of EN 10294-1 Grade 20MnV6 hollow bars is preferred over regular pipes. Although hollow bars look like pipes or tubes, they differ from either of the two with regards to their wall thickness. Generally, manufacturers use dimensions that are much thicker to ensure the walls of the EN 10294-1 Grade 20MnV6 Carbon Steel Seamless Hollow Bars remain broader.
In comparison to a regular solid bar, there are several points that separate the two. For one, the weight of a hollow bar is much lighter than the conventional solid bar. The absence of a densely packed metallic core in the product is the reason for the lower weight of the EN 10294-1 Grade 20MnV6 Carbon Steel Hollow Bars. The next point of difference is the cost of production. Even if both solid and hollow bars were produced using the same material, the hollow core reduces the material consumption during manufacture. Thus there are lower alloying costs as well, leading to the 20MnV6 Hot Rolled Hollow Bar having a relatively lower price. Despite these differences, there is no marked difference between the mechanical properties of both the solid or hollow bars. In fact, the strength of the 20MnV6 Hollow Bar remains equivalent to its solid counterpart.
