From an old fashioned guy who has no cell phone and had to look up the meaning of app. When I started learning about blacksmithing in the mid 1960's, I found a U.S. Government Printing Office booklet, 1966, that has helped me over the years, It is National Bureau of Standards Monograph 88, "Heat Treatment and Properties of Iron and Steel."  Admittedly, one must be circumspect in its use, because some material may be outdated, but it is surprising the amount of heat treatment info that can be applied to current steels on the market. It is on line free at Google, Books.

  Frank, here is the book you mentioned online:  http://digicoll.manoa.hawaii.edu/techreports/PDF/NBS18.pdf

 

By the way, it was nice visiting the other day.

Amazing app, lots of good information on heat treating.

thank you.

Nice thanks for sharing 

Finally got rid of my flip phone, and this is the first app I got. All I gotta say is 'Yee haw'.

Mr. L. Jockey,

Thank you for running down the reference.

I have "bookmarked" that reference.

But is this publication still "in print". I would be happy to buy it. (sometimes Government printing offices hang on to unsold stock, hope hope).

Again, bully for you, thanks & have a great day.

p.s. reading on-line publications of book length, gives me eyestrain, it is hard to flip back & forth whilst reading the text. Each electronic repository has its own syntax & method of organization, necessitating special effort to acquire its idiosyncratic lay-out. YECCCH !!

And reading same in the bathtub is a recipe for electrocution.

etc. etc.

In other words,  it is a Royal pain in the lower affasn(eh)ris.

Regards to all.

SLAG.

Thanks Mr. Newman I appreciate the info for the app, It's gonna answer a lot of questions

It's the data from this book I'm pretty sure. It's available at all the standard on line places that deal in books. Google will find it,, and its expensive. 

"Heat Treater's Guide, Practices and Procedures for Irons and
Stteels, 2nd Edition, (1995), Materials Park, OH 44073"

Mr. jockey,

Thank you for your generosity in supplying the reference.

It IS appreciated.

Have a safe, prosperous, healthy. and happy 2018.

(Hey! let me expand that wish to all i.f.i. denizens.)

Excellent app. Just downloaded and using it. Thank you for sharing

Well I don't have a smart phone; but does it take in account the cross sectional area?  I know bladesmiths working from even the ASM handbooks have to make changes to recommendations based on the fact that they are not using the "standard" 1" cross section all the charts are based on.

I don't have a smartphone, but I did install the app on my tablet some time back. Nice app.

It does for some. 1095 for sure. Perhaps for the more common steels used by knifemakers.

I ran across this image a couple days ago. It is something you could print off for reference. Or even better, get a screen in your shop and display it digitally!

I was wondering if anyone else has tried the heat treaters companion app for their smart phone. I downloaded it and it seems pretty informative as to chemical composition, ideal forge temps both high and low, and proper heat treating sequences for different grades of steel. I forge mostly mild steel, some spring steel, and high carbon for knives (plus the occasional "mystery metal" that gets scrounged up from convenient roadside scrap heaps). If you've used this app, let me know if you've found it useful

are you serious ?  read this before posting again

 

xxxx, I search barred this prior to posting a new thread.....nothing. But yes, i was serious.

Well that is what the entire 2 pages of this thread is about. start at page 1 and read. Question has been answered.

Steve

Steve Sells, pardon my impropriety, but I DO run a topic through the search prior to posting. The search pulled up no result when I used it, therefore I posted a new thread. No need for hostilities over it. Again, my bad

I didnt get hostile.  I posted to the "read this first" thread, it explained a few things you seemed to have missed, including how to search IFI to get results.  Also I did point out you were not looking when you posted, it is the first thing at the top of this page.  You did not look or read at all for yourself, and to blame me wont help

How long has the search bar been useless?

 

since the developers improved it many years ago, they also improved the photo storage retrieval system to not work so well either.  they have caused  staff more trouble than I will list,  but for now we are stuck,  it isnt easy to transfer a forum this size to another platform
