Uddeholm Ramax HH


Uddeholm Ramax HH is a corrosion resistant holder steel with good machinability, supplied in a high prehardened condition. Good machinability and corrosion resistance reduces tool manufacturing and maintenance costs. <ul> <li>Low mould production cost thanks to low wear of the cutting edges in the milling and drilling operations and shorter machining time thanks to increased cutting speed possible.</li> <li>Lower mould maintenance costs due to corrosion resistance</li> <li>Lower production costs since water cooling channels are less effected by corrosion, ensuring consistent cycle time</li> </ul>
