Case hardening steels are a group of suitably alloyed low carbon steels. These steels, when heat treated, absorb and diffuse carbon onto the surface. This is known as Carburization.
High Tensile steels are a group of carbon steels which are suitably alloyed to improve their hardenability. The improved hardening ability allows these steels to be heat treated to achieve levels of strength greater than plain carbon steels, in the same size range.
Chrome bar (Chromium plated) is normally electroplated or cold finished product suitable for applications including heavy equip plants, hydraulic cylinders, and general machinery.
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.
Most of our customer require greater strength than pure aluminium affords. By adding other elements to the pure form of aluminium creates better strength andor machinability.
Phosphor bronze continuous cast, centrifugally spun bars and hollows are provided by Global Metals. The production methods provide advantages of tight grain structure, elimination of inclusions, excellent mechanical and machining properties, resulting in savings in machining and tool wear.
