Ok. If not the right place, mods please move.

Hello knife makers. Non knife maker and non metallurgist here. So forgive me if this is a stupid question.

I work with some pretty nasty chemicals. HCl anhydrous (which isn't corrosive in itself) and up to 40% hydrous, among other things. Stainless is not much better than carbon at resisting it. As you can imagine, tools don't last long including knives.


Anywhere we need superior corrosion resistance or erosion resistance, we use hastalloy. Usually c-276 but I understand c-22 is even superior to that.

Question is, how would it fare for knife making? Would it's superior erosion resistance help anything? Can it be hardened as there is no iron content at all (that i saw in the assay's I looked at)? If I was to obtain a slab, and have a maker make the custom I am imagining, would it even be worth the money or effort and be useful?

Be gentle please. Lol
 
The Hastalloy family of alloys was developed for durability and corrosion resistance,
not wear applications, so would likely not be a good candidate for a cutting tool.

I'm not sure if wear and erosion resistance are different properties. We use it not only where it's corrosive but also where solids moving at high velocities cause erosion. It withstands that very very well also (think sand blaster tips, etc). In fact, we use hastalloy impingement rings to clad carbon vessels to decrease cost and increase life. Works great for that. However, of that is different than properties needed for wear resistance, I understand (well not really understand but can admit metallurgy is above my head)
 
Reading about this alloy dosent suggest any cutting tool application....and analysis
dosent suggest hardenability necessary for supporting a cutting edge.
