Atomized Low Alloy Diffusion and Hybrid Metal Powders
Ancorsteel® 4300: Ancorsteel® 4300 alloys are press-ready, bindertreated chromium steels for high performance applications. Excellent strength, hardenability, fatigue and toughness characteristics in the single press/single sinter condition provide a costeffective alternative to alloys that require secondary thermal treatments. High temperature sintering is recommended with these alloys to achieve optimum properties. Two levels of molybdenum are available to provide cost and performance options. Enhanced hardness and strength can be achieved with accelerated cooling in the sintering furnace. Other advantages of the alloy system include good compressibility and dimensional stability.
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.
Distaloy® 4600A / Distaloy® 4800A: Distaloy steel 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.
Ancorbond® FLM Alloys: are press-ready, binder-treated Mn-Mo hybrid alloy systems that are Ni and Cu free. These cost-effective alloys can be sintered at 1120 °C (2050 °F) using N2-H2 atmospheres and conventional sintering practices. Excellent hardness and strength can be achieved with accelerated cooling in the sintering furnace, delivering properties comparable with more highly-alloyed, diffusion-alloyed and hybrid steels.
