Ancorsteel 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/cm 3 and above.
The composition is balanced to give excellent properties along with close dimensional control.

Application

• Parts requiring greater toughness than attainable with conventional P/M materials. Ancorsteel FD-4800A is recommended for more severe conditions.

• Parts subjected to brinelling type of loading.

• Parts subjected to dynamic loading.

• Parts with close dimensional tolerances.

Compressibility and Green Strength
The diffusion-alloying technique used in making the Ancorsteels retains the high compressibility of the base atomized iron. Both powders have good green strength in the design density range.
