52100 Heat Treat Recipe
Ive searched, and came up empty. I know there must be a post here somewhere but I couldn't find it.
I forging a 52100 blade after being away from it for 3 years. I will be using a gas forge, and working with a magnet. If anyone has a good method of heat treating 52100, Id appreciate it! What type of quench you are using would be helpful also. Thanks in advance. God Bless Mike __________________ "I cherish the Hammer of Thor, but I praise the hand of God" |

52100 is not a simple steel and for proper performance temperature and time control are important . At least use a thermocouple in that forge. BTW annealing 52100 or any high carbon steel can cause serious problems.

Hey Mike, have you asked Len Landrum? He makes the toughest darned 52100 blades of anyone I know. At Bowie's this year Wiggins took a 1/8" deep chunk out of the steel frame of the cutting table with no discernable damage to the edge of his blade, 52100 HT'd by Len. If you don't have his number, PM me and I'll hook you up. I know he'd like to hear from you!

mete,
I have the means to do the controls (heat treat oven and high temp salts) and I would really like to hear your detailed advice on heat treating 52100 from start to finnish. if you have alredy done that in another thread etc. could you direct me to it? Thank you very much. |

I suggest looking at these two pages as a start:
http://www.crucibleservice.com/esele...bon/52100.html & http://www.cashenblades.com/info/steel/52100.html Who knows how long the Crucible page will stay up. __________________ Cap Hayes See my knives @ knives.caphayes.com This quote pains me: -- "Strategically placed blood grooves control blood spray in covert deanimation activities." -- |

I don't have anything specific but Cashen's info is as good as any. He started a long thread on BF about hypereutectiod steels and that is a good general discussion about those steels .Well worth reading that thoroughly.
You mention a magnet but that has no use for you , rely on temperature controls. Max forging temp - 2100 F Mf -235 F , Ms - 480 F I could answer specific questions better than general. |

There was a good discussion of heat treating 52100 on hypefreeblades forum. It was pretty much lead by Kevin Cashen. You might log in over there and do a search.

The first thing you must remember is that it was designed specifically for bearings, so the process recommended by industry needs to be adjusted slightly, something I seldom find with many other steels, where problems often arise from folks no sticking to the procedures closely enough. So ignore the standard industrial hardening heat and go for 1475F instead. |

Mr Cashen Go to 1475 and soak for how long for .058 and .078 thousandths thick 52100. Then temper to what degrees and how long and how many times. Do I need to put in liquid nitrogen. And how hard can I get 52100 for a thin slicer. Red

I rarely soak fro more than 10 minutes, unless there is something amiss in the carbide size and dispersion. Tempering is a matter of Desired Rc hardness for that specific blade (tempering effects will depend largely on the outcome of the quench and the amount of carbon locked in solution). For most knives, that I would use this alloy on, I would start at 350?F and not exceed 400?F. Tempering should always be around 2 hours in total time.
