1085/416/52100 San Mai All Integral Kitchen Knife

[ArielSalaverria]

This is a completely integral san mai kitchen knife I've made with 1085 and 416 (C 0,15% and Cr 12%) with a 52100 core. It has 13" overall and a 8" blade.

To make it I've used a capsule to place the materials, but I didn't weld it to seal it hermetically. To reduce the Cromium Oxide problem, I painted each of the steels with a flux made of Fluorure Potassium and Boric Acid.

This stainless steel (416) get an interesting effect after placing on the ferric perclorure, as the acid also attacks the stainless steel, as well as the 1085, although not in the same measure.

In my modest understanding, this is because the Cromium on it precipitates in Cromium Carbures and because it absorbed Carbon from the 1085 steel.

Although hard to notice on the pictures, it gets somewhat of the color of Titanium on satinized Duraluminum.

I'm still evaluating the stainless properties of the 416 as it's obvious that the layers of this steel were affected somehow by this process.

Thanks for looking!

Hi Ariel, A very interesting project. How did the actual welding process work with the 416/1085. Did you make the two sides seperately then weld those to the core of 52100. Was that a hard weld to make with the 416/1085. I would never have thought to try that combination. Fred

Fred,

I've always weld all the materials together on a capsule/cannister
