About this file
This is a technical solicitation document for custom machining and heat treatment services for pure iron components required by Oak Ridge National Laboratory's High Flux Isotope Reactor (HFIR) program.
The solicitation requires machining and post-processing of multiple pure iron parts from ARMCO® soft ingot iron sheet stock (3 sheets, 40mm thickness, 500mm x 500mm each). All work must follow a strict three-step process: (1) electropolishing surface finish without plating or powder coating, (2) ARMCO heat treatment in a controlled atmosphere furnace at 950°C (±20°C/-10°C) with specific heating/cooling rates of 2-4°C per minute and minimum 90-minute hold time plus 15 additional minutes per 5mm thickness over 25mm, and (3) selective coating with either white powder coating (maximum 60-80 microns thickness on designated sides) or bright nickel plating on remaining surfaces. The solicitation includes detailed engineering drawings for ten distinct part types with varying quantities: poleshim (24 units), polecap (12 units), polecap_MIR (12 units), centerpoleshim (6 units), centerpolecap (6 units), yokeaddonb (72 units), yokecover (72 units), and smaller components with quantities ranging from 6 to 72 units. All parts require precise dimensional tolerances (±.200 inch for standard, ±.010 for double X, ±.005 for triple X) and multiple threaded holes and counterbored features. Quotations should include both machining costs and post-machining process costs separately, or machining costs alone if post-processing services cannot be provided. Contractors should contact frankli@ornl.gov for technical questions. Raw materials will be supplied upon order approval and unused material must be returned with completed parts.

Heat treatment of ARMCO pure ion
STEP 1: Finish the surface with electropolishing. DO NOT PLATE or POWDER coating.
STEP 2: ARMCO heat treatment with the following procedure. Please keep the furnace clean and DO NOT introduce any impurity such as carbon-bearing greases, residues, oils, or remnants of material from prior heat treatments in the furnace. A high temperature anneal used to optimize magnetic properties. The iron undergoes a solid phase transformation which results in small, refined grains and uniform composition within the matrix. If carbon and nitrogen levels are not sufficiently low, magnetic aging may occur.
Heating: 2 – 4 °C (4 – 7 °F) per min Hold Temperature: 950 °C (+ 20 °C / – 10 °C) / 1742 °F (+36 °F / -18 °F) Hold Time: A minimum of 90 minutes with an additional 15 minutes per each 5mm (0.2 in.) thickness over 25 mm (1.0 in.)
Cooling: 2 – 4 °C (4 – 7 °F) per minute until the change temperature is below 550– 600 °C (932 – 1112 °F).
The parts should remain in a protected atmosphere until the temperature of the parts is below 300 °C (572 °F).
STEP 3: Coat the parts with powder coating or Nickel with the appropriate masking per the drawing.
Raw material:
Teh following material will be provided upon the approval of the order and please return the unused material together with the parts.
3x ARMCO® soft ingot Iron sheet - T 40mm 500mm x 500mm
Quote instruction:
Please quote the cost of the machining itself and also the cost of the post machining processes. If you cannot provide both, please quote the machining itself.
