Ancorsteel 4600V is a water atomized low alloy steel powder containing nickel, molybdenum, and manganese which satisfies Metal Powder Industries Federation (MPIF) material specification FL-4600. Ancorsteel 4600V is particularly useful for conventional P/M parts requiring greater hardenability than is possible when using admixed or diffusion alloyed powders. It has good compressibility and green strength, enabling parts to be made easily to densities above 6.7 g/cm 3 . The use of nickel and molybdenum as the principal alloying elements permits Ancorsteel 4600V to be processed using conventional P/M, temperatures and atmospheres. Ancorsteel 4600V, because of its high degree of cleanliness and uniform chemistry, is ideally suited for powder forging (P/F) applications that require the hardenability and mechanical properties associated with cast and wrought steels. Part densities of 7.60 to 7.86 g/cm 3 can be obtained using hot forming pressures of 415–1100 MPa (30–80 tsi).

All mixes include 0.75 w/o zinc stearate. They were compacted to 6.8 g/cm3 and were sintered 30 minutes at 1120˚C (2050˚F)in a dissociated ammonia atmosphere.
Austenitized 840˚C (1550˚F) in D.A. for 30 min., oil quenched. Tempered 230˚C (450˚F) for 1 hr. in air.
The lubricant used in each case was 0.75 w/o zinc stearate. Graphite additions were adjusted until the sintered carbon analysis was 0.4 w/o.

Powder ForgingPower forging (P/F) is a natural extension of the conventional press and sinter (P/M) process, which has long been recognized as an effective technology for producing a great variety of parts to net or near-net shape. In essence, a porous preform is densified by means of hot forming in a single operation. Forging is carried out in heated, totally enclosed dies, and virtually no flash is generated. Powder forging, therefore, is a deformation processing technology aimed at increasing the density of P/M parts and thus their performance characteristics.
