Hollow Bars

Metal Yard is the best manufacturer of Hollow Bars. A Hollow Bar is a cylindrical shape. In the case of bronze, it is actually centrifugal casted and is commonly used in Bushings and Bearings. It is also used as hydraulic valve parts, pump rods, slides and more. 316L Austenitic Stainless Steel Hollow Bar is useful in applications where its low metal on metal friction is an advantage. For a hollow bar, welding is not used. There are two main ways to create hollow bar, with the process depending on material type and dimensional tolerance requirements. One method for creating hollow bar is called drilling. This process involves sending a drill through a solid bar stock of material. This process can produce highly accurate part dimensions for critical applications. The second method is centrifugal casting. This is when a round mold is rotated at high speeds as molten metal is poured into the mold. The force created by the spinning mold forces the molten material to the inside mold wall where it cools and hardens. Centrifugal casted 20MNV6 Hollow Bar tends to be dense and uniform. There are really only two metals that refer to hollow bar; stainless steel and bronze.

A 4140 High Tensile Steel Hollow Bar can be made to be extremely homogeneous and can also possess very tight dimensional tolerances. On the other hand, achieving tight dimensional tolerances can be more challenging with tube. Also, if care is not taken by the manufacturer, the welding process used for manufacturing tube can potentially create a lower quality product than desired. The excess weld metal should be removed to avoid stress concentrators in the welded tubing. Also, the tube should be annealed or heat-treated after welding to ensure that a homogenous product is being created. Welding processes can create different crystalline structures near the weld zone which could affect the desired mechanical properties of the tubing.
