Heat Treating and Metallurgy

07 March 2011, 03:34

I'll throw this out there and see if anyone is interested. Maybe I can pay you back a bit for the information on this site.

I graduated from Montana Tech in 2000 with a degree in Metallurgical Engineering and a minor in Welding Engineering. Since then I have worked for an Indiana steel mill designing products, and troubleshooting both our process and our customer's processes. Those are my credentials.

I have seen several long discussions on the heat treatment or re-het treatment of mauser actions, with the springfields and enfields being dragged along.

Would anyone be interested in more technical (or factual) information on this subject? I can cover the alloys used, heat treatment, why they did what they did, how this compares to todays arms, hardness testing, lug setback, and much more.

Let me know, one of the reasons that I became a metallurgist was to know how firearms are made, but more importantly, why parts are made the way they are.

I think that would be a great idea and perhaps a moderator could make it a sticky for future reference. This issue always seems to come up.

Thanks,

That would be the best contribution to this subject posted in a long time!

I'd love to learn more about it. I'm afraid you'd have to dumb it down for me, though!

I spent some time many years ago working on a labor gang cleaning one of the basic oxygen furnaces at Inland Steel's Indiana Harbor works in East Chicago.

Talk about heat treating! It would nearly melt your safety glasses when that huge lance blasted oxygen at Mach 2 speed deep into the maw of the BOF!

Mike,

You have experienced the joy or maybe horror of an integrated melt shop. I worked at the LTV's Harbor Works when I first graduated before they went belly up. It was quite an experience for a small town Montana boy. 100 foot plumes of slag and steel shooting into the air get your attention.

Please give me a couple of days, and I will start to post. I started on it over the weekend and it would probably work best in a few installments.

I'll cover the basics of steel first. Then hit heat treating, and case hardening (color and standard).

I'll finish up with my study of a 1934 Mexican Mauser, a VZ24 (manufacture date unknown), and an early manufacture Eddystone US Model of 1917. I cut pieces off of the tang on each Mauser to analyze. The Eddystone was in a boz of parts, and has a cracked receiver ring, so I cut it up for analysis out of curiosity.

I'll do my best to make the concepts clear and cover 'smithing issues in each section.

Well, hurry up, please.

P.S.

This is an affirmation of every other post.

I will also be eagerly waiting to read and learn more.

Thanks for your efforts!!

I'm an old retired metallurgist and have been on the forum for a number of years .Occasionally I interject a metallurgical comment !

Welcome to the group Jeremy .

I was wondering if there were more of my kind around here. I am still medium young, and working. Given the state of the union, I will not be able to retire. Enjoy your retirement for me

.

Please fact check my commentary. I posted the first installment as The Basics of Steel.
