Product Description

PM390/ASP 2052 HSS Grade - (Powder HSS T42), also known as ASP2052, is an exceptional high-performance powder metallurgical material. This alloy boasts an optimal composition of high cobalt (8%), high vanadium, high tungsten (10%), chromium, and molybdenum. It can be heat treated to achieve a remarkable hardness of HRC 67-69. The high carbon, vanadium, and cobalt contents endow it with abrasion resistance comparable to T15 and red hardness superior to M42. Thanks to its high hardness, fine grain size, and uniform carbide distribution, it is an outstanding choice for specialized cutting tools that demand high red hardness, exceptional abrasion resistance, and robust toughness. Ideal for machining nickel-base and titanium alloys, it excels in heavy-duty and interrupted cuts, making it perfect for gear hobs, shapers, milling cutters, twist drills, taps, and broaching tools.
