Ford Metalurgical Standards

Post by Ron Patterson » Wed Jan 05, 2022 4:10 pm

Recently in a thread discussing magneto clamp screws the material these were made of.
I knew magnet clamp screws were NOT Bronze and pointed out the original Ford print for the part indicated they were made of what Ford
called "S Brass". At the time I could not find my Henry Ford trade School listing of metalurgical make up of the various Ford manufacturing Ferrours and Non-Ferrous alloys used to make Model T Ford cars.
Today I found that list and here is a copy for you all. This came from circullum material used at Henry Ford Trade School Metalurgical Department. You will find Ford's unique name for each alloy and the exact metaligurical makeup. Z Bronze, S Brass, EE Steel and on and on.
Enjoy

The EE and F do not have any Chrome in them, more flex!

Thanks, Ron:
Does the Ford trade school handbook include tables showing the mechanical properties of the alloys? And if so, would you mind posting an image of those? All the best for 2022 and beyond, jb

Does the designation EE on crankshafts indicate there is no chrome in them?

Click on Ron's link and have a look. No chrome indicated.

I see the chart says no chrome.

Is that what EE means on an EE crank?

Doesn't directly mean that it does not contain chromium. It means that it's manufactured from "EE" grade steel, which incidentally contains no chromium.

Already did that look at these two links already posated above.

Thanks, Ron: All I see in each chart is metallurgical composition, not mechanical properties, ie, stress, strain, elongation at fracture, young's modulus, etc. And a single page for each file? Thanks, jb

JB
These charts only define metalurigical compositions.
Other original Ford specs define mechanical properties and I do not have them.

Thanks, Ron. I saw the spec's listed on the magneto screw print and that prompted the inquiry. And of course, the coldworking of brass screws in thread rolling, and heat treatments for ferrous alloy parts would determine those properties in the manufactured parts. Best, jb

1). Thanks for the update Ron...

2). Sometimes the drawings contain post process info and instructions...

3). Other times you have to have the Ford post processes, which are in a chart somewhere written by Wandersee which I managed to stumble across many moon ago...I never figured out whether (say) Heat Treat W applied to all of a certain class material, or was only used on certain in class-when actually specified.

4) There are also individual sheets here and there with tidbits that are rather obscure. Like, I KNOW the z-bronze was heat treated based on an article I read somewhere along the line. Was it Ford? Was it English Humber? I just don't recall now. Heat treated? Bronze? Whaddaya mean? Bronze usually behaves the opposite of steels when 'heat treated'. I think they really meant 'temper' but the temperature surprised me, it was like at 10 degrees less than the melting point of lead and I always wanted to run that down further as to why (I think they were looking for a wear characteristic early on...and just settle on this, if I can ever find it again.

5). There had to be a tensile rating file somewhere yet I have never seen one. Why? There are drawings that say 'use 60,000 tensile steel'

I always wanted to leave that stuff for retirement projects, run it all down again and this time catalogue and source it somewhere for someone else to follow. Problem is...now near all but retired, I can't find time to do much...good luck to the next guy...
