Hi Chet.

The " purer " the Iron, the better, those specifications look quite good.

It's just dawned on me that NMR might play a part in the process like the Meyer Mace device ??

Cheers Graham.

AISI 1008 and 1026 carbon steel seem most likely available


Steels containing mostly carbon as the alloying element are called carbon steels. They contain about 1.2% manganese and 0.4% silicon. Nickel, aluminium, chromium, copper and molybdenum are also present in small quantities in the carbon steels.

AISI 1008 carbon steel has excellent weldability, which includes projection, butt, spot and fusion, and brazeability. The following datasheet will provide more details about AISI 1008 carbon steel.
Chemical Composition

The following table shows the chemical composition of AISI 1008 carbon steel.
Element    Content (%)
Iron, Fe    99.31-99.7 %
Manganese, Mn    0.30-0.50 %
Carbon, C    0.10 %
Sulfur, S    0.050 %
Phosphorous, P    0.040 %
Physical Properties

The physical properties of AISI 1008 carbon steel are outlined in the following table.
Properties    Metric    Imperial
Density (composition 0.06% C, 0.38% Mn, 0.01% Si, annealed at 925°C)    7.872 g/cm3    0.2844 lb/in³
Mechanical Properties

The mechanical properties of cold drawn AISI 1008 carbon steel are tabulated below.
Properties    Metric    Imperial
Tensile strength    340 MPa    49300 psi
Yield strength (depending on temper)    285 MPa    41300 psi
Elastic modulus    190-210 Gpa    27557-30458 ksi
Bulk modulus (typical for steel)    200 GPa    29000 ksi
Shear modulus (typical for steel)    80.0 GPa    11600 ksi
Poisson’s ratio    0.27-0.30    0.27-0.30
Elongation at break (in 50 mm)    20%    20%
Reduction of area    45%    45%
Hardness, Brinell    95    95
Hardness, Knoop (converted from Brinell hardness)    113    113
Hardness, Rockwell B (converted from Brinell hardness)    55    55
Hardness, Vickers (converted from Brinell hardness)    98    98
Machinability (based on AISI 1212 steel as 100 machinability) The machinability of group I bar, rod, and wire products can be improved by cold drawing)    55    55
Thermal Properties

Thanks ,seems you landed the holy Grail......and I learned something new ?? [almost.... hopefully more after I speak with them on Monday]
if iron holds some secrets towards excess energy harvesting , this info seems crucial towards understanding micro environments which can happen in these experiments . 

your link again
 http://www.goodfellow.com/E/Iron-Rod.html


snip
Depending upon the temperature, pure iron can exist in three forms, namely alpha-, gamma- and delta-iron; alpha iron is a polymorphic form of iron which is stable below 906C; it has a body centred cubic lattice (bcc) and is magnetic up to 768C. Gamma iron is a polymorphic form of iron which is stable between 906C and 1403C; it has a face centred cubic lattice (fcc) and is nonmagnetic (n.b. its range of stability is reduced by the presence of carbon, manganese and nickel and it is the basis of the austenite solid solutions). Delta iron is the polymorphic form of iron which is stable between 1403C and the melting point; it has the same lattice structure as alpha iron.
end snip
==============================================================
here is ions historical link for a reference to the time frame of the patent and where wire technology  was in Cook's time [patent date 1871

as ion said " a good read" [fascinating techniques ,time period information and evolution ,
http://fortepianos.com/iron%20wire.pdf

-----------------------------------------------
 on a side note makes me wonder about a whole new group of experiments under heated conditions ,and whether the anomalies seen
in micro environments [Like Mikes damaged stainless,or Celani and other ] can be better understood and utilized for true excess energy harvesting .

I've tweeted Goodfellow about pricing as the price link on their page is a 404.
