Ancorsteel 85 HP
®
Ancorsteel 85 HP is a water atomized,
prealloyed low-alloy steel powder for high
performance applications. The prealloyed
0.85 w/o molybdenum addition allows
exceptionally high compressibility and
provides good response to heat treatment.
Ancorsteel 85 HP is a good base powder for
a wide range of hybrid alloy systems.

Powders with a 0.6 w/o graphite addition were compacted at a pressure of 550 MPa (40 tsi).
Heat treatment was performed at 900ºC (1650ºF) for 30 minutes in dissociated ammonia followed by quenching
in oil preheated to 60ºC (150ºF). Tempering was performed for 60 minutes in argon to prevent decarburization.

All specimens were compacted at 620 MPa (45 tsi) and sintered for 30 minutes in dissociated ammonia. Heat treatment was
performed in a production furnace at 840ºC (1550ºF) in an endothermic gas atmosphere followed by quenching in oil preheated
to 60ºC (140ºF). Tempering was carried out at 200ºC (400ºF) in air.
