Hollow Bar

Global Metals for many years now have been the exclusive stockists and suppliers of Ovako hollow bars in Australia. Ovako hollow bars, or seamless mechanical tubes as they are known, are manufactured in the steel grades Ovako 280 and 495 (high strength micro-alloyed steel). The tubes have a very wide range of uses, from load-bearing structural elements to precision made components to meet high demands in machinability and fatigue strength.

The steels are manufactured in a special electric arc furnace in accordance with Ovako’s special MR process which has advantages over conventional methods and results in purer steel. This modern development permits close control of steel chemistry and produces steel with narrow analytical tolerances and low levels of harmful slag inclusion. Other advantages are the grain-refined steel produced, its high and uniform machinability and very good weldability.
