Alloy 718 Powder Specifications/Statement of Work

Scope:

These Specifications provide the necessary details for 2,500 kilograms of Nickel Alloy 718 Additive Manufacturing/Laser Sintering powder to be procured by The George C. Marshall Space Flight Center (MSFC). The Nickel Alloy 718 powder, also known as Inconel 718, must meet the following requirements in order to work properly in the laser sintering machine.

Requirements:

1. The Nickel Alloy 718 Additive Manufacturing/Laser Sintering powder must be spherical in shape.

2. The Nickel Alloy 718 Additive Manufacturing/Laser Sintering powder must be in the particle size range of 10-45 microns.

3. The Nickel Alloy 718 Additive Manufacturing/Laser Sintering powder must be gas atomized (i.e. in argon) for purity.

4. The Nickel Alloy 718 Additive Manufacturing/Laser Sintering powder must be shipped in inert packaged containers or drums no larger than 20 kilograms each.

5. The Nickel Alloy 718 Additive Manufacturing/Laser Sintering powder shall have composition as follows:

Ni (50-55 wt-%) Cr (17.0-21.0 wt-%) Nb (4.75-5.5 wt-%) Mo (2.8-3.3 wt-%) Ti (0.65-1.15 wt-%) Al (0.20-0.80 wt-%) Co (≤ 1.0 wt-%) Cu (≤ 0.3 wt-%) C (≤ 0.08 wt-%) Si, Mn (each ≤ 0.35 wt-%) P, S (each ≤ 0.015 wt-%) B (≤ 0.006 wt-%) Fe (Balance*)

*Reference to the ‘balance’ of a composition does not guarantee this is exclusively of the element mentioned but that it predominates and others are present only in minimal quantities.

6. The Nickel Alloy 718 Additive Manufacturing/Laser Sintering powder will be delivered with Certificates of Conformance to requirements herein.

Deliverables:

The following items shall be quoted and delivered to MSFC:

1. Nickel Alloy 718 Additive Manufacturing/Laser Sintering powder, Qty 2,500 kilograms Schedule:

The Nickel Alloy 718 Additive Manufacturing/Laser Sintering powder shall be delivered to MSFC on or before July 31, 2016.
