Micro-Melt® Maxamet®

Micro-Melt® Maxamet® is a high alloy content, super-hard, high speed powder tool steel possessing properties intermediate between conventional high speed tool steels and cemented carbide. The high room temperature and hot hardness of this alloy allow it to be considered for use in applications where conventional tool steels do not hold up, such as in dry machining. The Balanced alloying additions allow it to provide excellent wear resistance due to a high carbide volume, but to maintain good toughness at high hardness levels. In addition, the combination of high hardness, hot hardness, and high temperature stability make the alloy a candidate for applications in which tools are coated prior to service. Possible applications could include those where high speed steel is currently used and an upgrade is desired but the switch to carbide is unattractive due to cost, tooling manufacture, toughness, or machine rigidity concerns; or applications where carbide is currently being used but is not cost-effective due to limited production runs or toughness/breakage problems.
