From North American Höganäs, Inc.
One area where powder metallurgy has proven to be superior to other means of manufacturing is wear resistant structures. Highly wear resistant high speed steel powders are commonly used in both HIPped and pressed and sintered forms. The carbide size and structure obtained depends both on production conditions and carbide type but the carbide types are fixed by the alloy composition. Alternative carbides have different properties and can be introduced in new alloy compositions. This paper presents the development of a new material where the carbides are designed to be of the most useful type for a sintered tool steel. A mix of small hard carbides and larger less hard carbides in a matrix capable of being hardened gives a good combination of properties. In some applications, the properties achieved are more effective than those obtained from the pressed and sintered M3/2 and M2 currently in use. Products & Services
Carbides and carbide materials include silicon carbide, tungsten carbide and titanium carbide as well as other compounds of a metal (Ti, W, Cr, Zr) or metalloid (B, Si) and carbon. Carbides have excellent wear resistance and high hot hardness.
Powders are finely divided or powdered forms of metals, ceramics, polymers, composites, minerals or other raw materials.
Balls and sphere shapes are used for check or ball valves, bearings, or other applications requiring a spherical product. They are fabricated from materials such as carbides, ceramics, sapphire, metals, plastics, rubber and elastomers.
Isostatic presses are used for compressing powdered materials into shaped pre-forms or general products. There are two main types of isostatic presses; cold isostatic presses (CIP) that function at room temperature and hot isostatic presses (HIP) that function at elevated temperatures.
Master alloys and alloying additives are alloy element concentrates, grain refiners, hardeners, deoxidants and other agents added into a melt or metal powder blend to produce a particular alloy, modify a melt or alter processing characteristics.
