Forging Issues
Hello wootz guys,
Experienced my first serious issue with forging on some crucible steel. I am a bit at lost as it what actually going on. I’m aware hot-shortness is a common problem but I don’t think that is this. I did have a crack from on the tip pretty early and cut that out, than I thought there was some wild scale that just didn’t wanna fall off, figured it was a weird thing with the carbides.
However after I stopped and cleaned the blade, some immediately (scale or peeling) came back with reforging and they seemed to repeat in the same areas.
Overall most of the blade looks fantastic! But I gotta clean some areas that may change the profile more than I want.
Here is a pic of the cake and some pics of what I experienced.
Note: It forged to large bar without issues and seemed to lower temp forging as a culprit. This mix was different and contained half 1018 so it was much much higher in MN. The other possible thought was I tried slow cooling this a little different , so far those are my two best guesses! 😬

Interesting, I was a bit shocked on the forging too cold as I worked this billet "to the best of my ability" identical to previous ones. But the chemistry difference you mentioned, I may have overlooked.
For that shear pic, that color is after reviewing the damage for a bit and decided to record. It was a forged down the width plane to try and even out some. Bummerrrrr, I can say I don't believe P to be my culprit here. This mix was getting the phosphorous from wrought iron, which I had less of that in this particular ingot but was from the same wagon wheel. The replacement material had little to no P, so I can only be less and that is my thought process.
It appears my overconfidence with the early success of the others had me make some rookie mistakes. One the bright side I did still get the sword out of it, but I started forging it hotter that time 🙂
