Ancorsteel FLD-49HP is a nickel copper-molybdenum alloy steel powder developed for high-performance sinter-hardening applications. This alloy conforms to MPIF Material standard 35, designation FLDN4C2-4905. The nickel and copper are diffusion-alloyed to the molybdenum pre-alloyed powder during processing to maintain good compressibility while enabling high hardness and toughness in sinter-hardened parts. This datasheet provides information on composition, physical properties, and tensile properties as well as fracture toughness. It also includes information on powder metal forms. Filing Code: SA-809.
