UDDEHOLM HIGH PERFORMANCE STEEL

1 UDDEHOLM high PERFORMANCE STEEL . Getting the best results demands care. It all boils down to carefully selecting the right material. Through every step, in every component. Having Udde- holm as a partner gives you the sounding-board you need when it comes to finding cost-effective new solutions. To ensure we do the best possible job we want to be involved in the entire process from your initial ideas right through to the finished product. UDDEHOLM is a world leader in developing and manufacturing tool STEEL . We are now going one step further by offering our STEEL know-how and STEEL grades, such as UDDEHOLM high PERFORMANCE STEEL . Dragbike slider clutch made from seven different grades of UDDEHOLM STEEL .

Edition 3, The latest revised edition of this brochure is the English version, which is always published on our web site 2 UDDEHOLM high PERFORMANCE STEEL . Better profitability with UDDEHOLM high PERFORMANCE STEEL UDDEHOLM high PERFORMANCE STEEL is a new concept in the world of STEEL , with new areas of application for UDDEHOLM 's first-class steels. By using UDDEHOLM STEEL instead of engineering STEEL in parts subject to large stresses and strains, you can benefit from the superior properties of tool STEEL .

3 UDDEHOLM high PERFORMANCE STEEL is a concept whereby the properties of tool STEEL are harnessed and used in contexts other than pure tool applications. Maintenance costs industry large sums of money each year. A high proportion of these costs can be avoided by selecting a STEEL with better material properties. UDDEHOLM high PERFORMANCE STEEL offers more advanced steels that produce better results. Thanks to their improved strength and wear resistance the STEEL grades have a longer life span, resulting in better overall economy. Go for a better STEEL it pays. UDDEHOLM high PERFORMANCE STEEL 3. Care in material selection leads to lower operating costs When it comes to choosing materials for machine REDUCE THE RISK OF BREAKDOWN.

4 Parts, care is key. This may seem obvious, but all too WITH A REQUIREMENT ANALYSIS. often companies simply do exactly what they usually Rather than following the conventional division do without considering that there could be a better between steels for machine parts and steels for solution than using the STEEL conventionally used for construction, make sure a thorough need and that application. requirement analysis is carried out.

Higher wear resistance longer life span UDDEHOLM 's product programme includes steels from size. Wear resistance can therefore be balanced with other 200 400 HB in delivery condition, as well as steels desirable properties such as toughness and ductility. The that can be hardened to 68 HRC with a carbide content durability of most UDDEHOLM high PERFORMANCE Steels of up to 25%. The carbides have a Vickers hardness of can be enhanced by means of various recognised surface 1600 2800 and vary in size from 1 to 15 microns.

Fewer stoppages and higher strength Usually the term strength' not only refers to the yield and smaller-sized slag inclusions, which has a positive point and breaking point, but also fatigue strength, impact on fatigue strength. Selecting the appropriate toughness and ductility.

9 STEEL and method of heat treatment makes it possible to increase strength whilst maintaining ductility and The breaking point increases linearly with hardness, increasing fatigue strength. It may also enable a reduction while a higher breaking point can mean lower toughness, in dimensions and a lighter construction. Care should the ability to resist brittle fracture. Ductility is the however be taken with applications subject to below- ability to resist initial cracking and can be improved zero temperatures, as the transition temperature is through a higher purity of STEEL .
