Individual Product Datasheets for Atomized Low Alloy Steel & Metal Powders

Ancorsteel 4300: Is the first in a new line of engineered high performance binder-treated products that simulate wrought steel compositions and can be processed at conventional sintering temperatures.

Low sintered oxygen levels (500 ppm) are achieved in this unique Cr-bearing alloy when processed at 1120ºC (2050ºF). The graphite level can be tailored to the demands of the specific application. Other advantages of this alloy include good compressibility, and exceptional dimensional stability with respect to graphite content, compaction pressure, and sintering conditions.

Ancorsteel 721 SH: Is a water atomized, prealloyed atomized steel powder specifically developed for sinter hardening. It complements Ancorsteel 737 SH as it contains slightly lower levels of molybdenum and nickel. Ancorsteel 721 SH may be used for applications where the slightly higher hardenability of Ancorsteel 737 SH is not required. With good compressibility and stable dimensional change Ancorsteel 721 SH is the powder of choice for small to medium size parts that are to be sinter hardened.

Ancorsteel 737 SH: Is a water atomized, prealloyed atomized steel powder specifically developed for heat treatment by either the sinterhardening process or conventional quenching and tempering. The primary characteristics center on excellent hardenability in conjunction with good compressibility, particularly at higher compaction pressures. This unique combination of attributes differentiates its performance and optimizes both static and dynamic strength. Low sintered growth, resulting in higher sintered densities, along with stable dimensional response are major hallmarks which enhance suitability for a wide range of demanding applications. In some instances, the exceptional hardenability provides a means of sinter-hardening without requiring accelerated cooling equipment or high percentages of admixed additions.

Ancorsteel 2000: Is a water atomized low-alloy powder metal containing nickel, molybdenum, and manganese which satisfies Metal Powder Industries Federation (MPIF) material specification FL-4200.

It has good compressibility and green strength, enabling parts to be made easily to densities above 6.7 g/cm3. 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.

It is more highly alloyed than the hybrid alloy Ancorloy 4. Tempering as-sintered compacts made from Ancorloy HP-1 improves their tensile strength and tensile ductility.

Ancorsteel Phosphorus Alloys: Are ferrous base powders for P/M parts requiring superior electromagnetic performance. Compared with parts made from pure, high compressibility iron powders, those made from the phosphorus alloys have higher resistivity, permeability and induction, and reduced coercive force. The presence of phosphorus also decreases the susceptibility of a P/M component to nitrogen aging. Ancorsteel phosphorus alloys are produced by making ferrophosphorus additions to the highly compressible iron powders Ancorsteel 1000B or Ancorsteel 1000C. Components made from the phosphorus alloys exhibit a good combination of tensile strength, ductility, and impact absorption energy. The particle size of the added ferrophosphorus is important as it has a significant effect on these properties. The ferrophosphorus powder should be finer than 20 micrometers and preferably should have a median particle size close to 10 micrometers. The Hoeganaes products Ancorsteel 45P and Ancorsteel 80P contain 0.45 and 0.80 weight % (w/o) phosphorus respectively. Typical applications for parts made from Ancorsteel phosphorus alloys include speed sensors, magnetic solenoids and plungers.
