Latrobe Dynamax™ ASTM M42, DIN 1.3247 Super High Speed Steel

 

Subcategory: Cobalt Alloy; High Carbon Steel; Alloy Steel; Metal

Close Analogs: Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.

Material Notes:
Dynamax super high speed steel is a premium cobalt high speed steel with a chemical composition designed for high hardness and superior hot hardness. These properties make the steel an excellent choice for machining high-strength and prehardened steels, high-hardness alloys, and the difficult-to-machine, nonferrous superalloys used in the aerospace, oil, and power generation industries. Dynamax super high speed steel exhibits excellent wear resistance by virtue of high heat-treated hardness (68 to 70 HRC), and the high cobalt content imparts the hot hardness. As such, the cutting edges on tools made from Dynamax super high speed steel stay sharp and hard in heavy-duty and high-production cutting applications. Typical applications for Dynamax super high speed steel include twist drills, taps, milling cutters, reamers, broaches, saws, knives, and thread rolling dies.
