Jaro Petrina Posted March 22 Share Posted March 22 What I am doing wrong here, was I over the quench temp with 52100 ??? Link to comment Share on other sites More sharing options...
Jerrod Miller Posted March 22 Share Posted March 22 There is pretty much no such thing as too many normalization cycles for 52100. How many did you do? What was your whole process to get here? Link to comment Share on other sites More sharing options...
Jaro Petrina Posted March 22 Author Share Posted March 22 2, however, no soak. I think thats the problem and also quench temp too high Link to comment Share on other sites More sharing options...
Alan Longmire Posted March 22 Share Posted March 22 It definitely got overheated at some point! For 52100 I use four or five normalizing cycles and no soak at all after forging. For quenching I may let it soak for one minute once it's at heat, but usually not. Link to comment Share on other sites More sharing options...
Jaro Petrina Posted March 22 Author Share Posted March 22 The blade is gone, off course, but when it gets so coarse, can I just normalise again and quench again? Should make martensite again no? Link to comment Share on other sites More sharing options...
Jaro Petrina Posted March 22 Author Share Posted March 22 scratch that, can you tell me whats your normalisation temp and do you just aircool? Link to comment Share on other sites More sharing options...
Alan Longmire Posted March 22 Share Posted March 22 I watch for decalesence, I don't know the temperature. And yes, air cool to black in a dark room, then back in the forge. Link to comment Share on other sites More sharing options...
Joël Mercier Posted March 23 Share Posted March 23 According to Verhoeven and Larrin's testing, a DET anneal will give you the best structure for hardening. But it's not a viable option when you forge HT. Still, plenty of good info https://knifesteelnerds.com/2019/05/13/how-to-heat-treat-52100/ 2 Link to comment Share on other sites More sharing options...
Doug Lester Posted March 23 Share Posted March 23 Others may not agree but I like to cool to black and check the blade with a magnet to be sure that phase change has occurred before returning the steel to the forge.. The magnet should stick to the steel. Doug HELP...I'm a twenty year old trapped in the body of an old man!!! Link to comment Share on other sites More sharing options...
Jaro Petrina Posted March 23 Author Share Posted March 23 Well it would have been a nice knife. Link to comment Share on other sites More sharing options...
Gary LT Posted March 24 Share Posted March 24 What temperature did you quench this at? 52100 has been my steel of choice last few years Gary LT "I Never Met A Knife I Didn't Like", (Will Rogers) Link to comment Share on other sites More sharing options...
