Heat Treatment of Steel

[JCKelly]

I, being a metallurgist, am absolutely in awe of this new heat treat book, put out by a furnace company, Seco Warwick. 
Now, before you all throw up your hands in HORROR at the detailed stuff only a metallurgist could love -

Take a look at pages 56, 83, 84 and 98. Just these pages.
page 56 - gives times & temperatures for different depths of carburization (case hardening, the depth of case one gets)
page 83 - heating, and tempering colors, described.
page 84 - melting points of lotsa metals
page 98 - quenching matters. Tells just exactly why a brine quench is superior to plain water. I sorta knew this, but not so exactly.

Grit your teeth and download this book.

Thanks.  I dig that stuff.

and the price is right.

It made itself a link.

Thank you JC.  I know just enough metallurgy to get myself into trouble, but my Dad was Chief Metallurgist at USS's Ensley Works, and this in addition to being practical information is a reminder of him and the old days.

very good stuff, thanks for posting.  Already learned things I didn't know for sure, specifically about case depths.  I was surprised to see how deep a case depth you can get even at the lowest time and temp ranges.  I always thought it would be in the .002-.003 range, but it is 3x-4x times that.    Re-enforces the idea not to heat and quench parts at too high of a temp, so as not to risk excessive warping and cracking, if it's not specifically needed.

Thanks again.

Great resource JC, thanks for sharing. Lots of useful stuff there. Saved that to my favorites.

Great stuff!
