Atomized Unalloyed Steel
Ancorsteel® 1000: This is the workhorse of our atomized powders, the material that has advanced P/M into the modern age of higher density compacts. More P/M components have Ancorsteel 1000 as their base than any other atomized powder. It has low levels of carbon and oxygen along with good compressibility. Ancorsteel 1000 provides excellent physical properties with small additions of graphite, copper, or nickel. Ancorsteel 1000 is also available with guaranteed low levels of inclusions for powder forging applications.
Ancorsteel®1000B: The second generation of atomized high compressibility powders. High purity provides greater compressibility than Ancorsteel 1000; densities of 6.8 g/cm3 at 410 MPa (30 tsi) are commonly achieved. The combination of purity, compressibility, and green strength makes Ancorsteel 1000B ideal for high strength, high density, multi-level structural components. This is the highest compressibility iron powder available.
Ancorsteel® 1000C: Compressibility ratings of 7.1g/cm3 at 550MPa (40 tsi) provide outstanding sintered properties at lower compacting pressures. With Ancorsteel 1000C, you can achieve densities equivalent to other powders with lower compacting pressures, and thus extend the effective working range of your compacting press. Due to its low oxygen and nitrogen levels, Ancorsteel 1000C is also used extensively for electromagnetic applications.
Ancorsteel® AMH: A low apparent density water atomized powder for structural applications. The atomizing process imparts a spongy morphology to the powder particles giving the material superior green strength for an atomized powder combined with good compressibility. The powder production process used to make Ancorsteel AMH involves refining of the liquid metal so that the oxide inclusions typically found in sponge products using the reduction process are removed.
Ancorsteel® 1015: A low apparent density water atomized powder for structural applications. The atomizing process imparts a spongy morphology to the powder particles giving the material superior green strength with good compressibility. Ancorsteel 1015 results in fast and uniform carbon pick-up during sintering and permits shorter sintering cycles. Dimensional change factors are lower especially in the copper steels.
