Individual Product Datasheets for Atomized Low Alloy Steel

Ancorsteel 50 HP: Is a new water atomized, prealloyed low-alloy steel powder for high performance applications. The prealloyed 0.50 weight % (w/o) molybdenum addition results in high compressibility and provides good response to heat treatment.

Ancorsteel 737 SH: Is a water atomized, prealloyed 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 steel powder 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 2000 to be processed using conventional P/M sintering temperatures and atmospheres. Ancorsteel 2000, 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/cm3 can be obtained using hot forming pressures of 415–1100 MPa (30–80 tsi).

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/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. Part densities of 7.60 to 7.86 g/cm3 can be obtained using hot forming pressures of 415–1100 MPa (30–80 tsi).

Ancorsteel FD-4600 / Ancorsteel FD-4800A: These Ancorsteel powders were developed to extend the capability of P/M parts to satisfy the needs of today's technology where higher strength and toughness are required. The alloy content is composed of nickel, molybdenum, and copper, and conforms to MPIF Material Standard 35, Material Designations FD-02XX and FD-04XX. Conventional sintering practice is adequate for meeting high performance requirements. The additives are diffusion alloyed to maintain compressibility of the base atomized iron. The recommended density range is 6.8 g/cm3 and above. The composition is balanced to give excellent properties along with close dimensional control.

Ancorloy 2 / Ancorloy 4: Is the material designation given to a new product line based on the use of a new Engineered Bonding Technology for high performance applications. The composition of these bindertreated premixed materials meets the chemical composition limits for the MPIF Material Standard 35 for Material Designations FD-02XX and FD-04XX respectively. The combined carbon level of the finished sintered part can be adjusted through a graphite addition in the premix. Equivalent tensile properties can be achieved with lower graphite additions for the Ancorloy Grades in comparison with the Distaloy 4600A and Distaloy 4800A materials.

Ancorloy DH-1: Is a new press-ready, engineered binder-treated premixed ferrous P/M material designed for sinter-hardening. It has comparable performance to a diffusion alloyed product of the same composition. Ancorloy DH-1 is a hybrid alloy based on Ancorsteel 150 HP to which 2 w/o copper has been added during a binder-treated premixing operation, It is designed for use in sinter-hardening applications that do not need the extremely high hardenability of Ancorsteel 737 SH.

Ancorloy HP-1: Is a new press-ready, engineered binder-treated premixed ferrous P/M material designed for enhanced as-sintered mechanical properties. It has comparable performance to a diffusion alloyed product of the same composition. Ancorloy HP-1 is a hybrid alloy based on Ancorsteel 150 HP to which 4 w/o nickel and 2 w/o copper have been added during a binder-treated premixing operation. 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.

Ancorloy MDA: is a new press-ready,engineered binder-treated premixed ferrous P/M material alternative to malleable and ductile cast irons. It is less highly alloyed than Ancorloy MDB and Ancorloy MDC. Parts compacted from Ancorloy MDA should be sintered at 1260°C (2300°F).

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.
