loneronin Posted January 27, 2008 Share Posted January 27, 2008 where can I find some good recipes for L-6 and MA5M heat treatment? I mean temperatures, time, quenching, tempering, anneling... Quote Link to comment Share on other sites More sharing options...
Rich Hale Posted January 28, 2008 Share Posted January 28, 2008 What are you going to make with them? Quote Link to comment Share on other sites More sharing options...
Pault17 Posted January 28, 2008 Share Posted January 28, 2008 out of curiosity, where are you? If you go into your User CP, you can give everybody a better idea as to where you are and if anybody is close by. I did not see L6 in this one, but here is an interesting siteDiehl Steel - D-2 Air Hardening tool Steel Quote Link to comment Share on other sites More sharing options...
markb Posted January 28, 2008 Share Posted January 28, 2008 This is from... Metals Handbook vol. 2 eighth edition "heat treating, cleaning and finishing" American Society for Metals I didn't find MA5Mb but this book is circa 1971 Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted January 28, 2008 Share Posted January 28, 2008 Generally the manufacturer will provide a spec sheet listing suggested heat treat info; or as Mark has mentioned the ASM handbook is a great place to find such info. Quote Link to comment Share on other sites More sharing options...
loneronin Posted January 28, 2008 Author Share Posted January 28, 2008 Rich, some kinves, what else???? Pault17, I'm from Italy (I just updated my profile). thanks for the link. markb, thank you for your scan! I found a piece of circular saw and I wanna try to make a knife with it. I have also some MA5M... I'm serarching info. Thomas, I'm downloading chapter 4 of the ASM handbook: "heat treating". seems really interesting! ciao Quote Link to comment Share on other sites More sharing options...
Rich Hale Posted February 1, 2008 Share Posted February 1, 2008 I thought maybe knives,and did not meant offend, but I do things a bit different for knivesdepending on use and size. A long blade knife from L-6 I would temper a bit softer that a short skinner. It is a great steel as I see it. enjoy Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted February 1, 2008 Share Posted February 1, 2008 Good Point most standard heat treat texts are based on items with at least 1" square cross section. Knives being *small* often skew things; like a standard water hardening steel will do better in wam oil, an oil hardening steel may harden in air in the breeze from a fan, etc. I've met some BNK (big name knifemakers) whose copy of the reference texts are so full of annotations and papers that they bulge to nearly twice their size. What it gets down to is that the reference works are a good place to start and then your testing and experience with a steel will modify their suggestions---why many makers suggest learning *1* steel throughly and then adding another alloy to your repertoire.

Quenchcrack Posted February 2, 2008 Share Posted February 2, 2008 One of the problems with an international site like this is that we tend to forget each nation has its own set of specifications and steel identification numbers. There are some cross references but they are ususally incomplete. I looked up MA5M in Woldman's Engineering Alloys (1500 pages in 1962) and did not find it. Could be an alloy unique to Italy.

loneronin Posted February 2, 2008 Author Share Posted February 2, 2008 yesterday I found these tables and surprise... the MA5M is the 420c. if you have something similar for other steels, please post it. could be useful for everybody.
