How to get Harmon with 1084

i am ready to heat treat a gyuto out of 1084. Is it possible to get a hamon ? Do I just use the high temp goo I use for w2? What's your advice? Thx

 

Is this Aldo's 1084? It's a bit higher in manganese than preferred, but it will definitely produce a hamon.

 

Yes it is. That's what I thought. Any advice? Using an evenheat kiln. Thx

 

Being eutectoid it's going to heat treat pretty simply. What are you using for a quenchant? And what 'goo' did you use for your W2 lol? Pictures of both would be awesome, just so I can see how your layout was etc.

Honestly, it's going to heat treat a lot like W2 to some extent.



Tempering Temperature and resultant Rockwell Hardness

°C - °F - HRC

149 - 300 - 65

177 - 350 - 63-64

204 - 400 - 60-61

232 - 450 - 57-58

260 - 500 - 55-56

288 - 550 - 53-54

316 - 600 - 52-53

343 - 650 - 50


^^^^^ is pretty much everything you need to know. Heat to 1450°F-1500°F, let soak about 5 minutes (not necessary with this steel, but I like to make sure everything is in solution), quench into canola oil.

 

Parks 50. I forget the name, but it is furnace sealant, used in Dave lischs w2 class mixed with some oil. It created a great hamon on w2. I have a picture of the actual tube on my phone, not available right now. What do you use. Thx for the info Chris!

 

Rutland's Furnace Cement? Black? I mix mine with water myself. I use either it or Satanite. The Parks should be fine, but might actually harden it a bit too quickly. It could be you need a thicker layer of clay than you did on the W2.

And any time my friend...glad to help!

 

Yes that's it! Thx! I appreciate your help! Eric

 

Any time! Feel free to share pictures, and don't hesitate to ask if you need anything else

 

Awesome Cris. Good luck Eric and I can't wait to see the pics!
