Something NEW from the Baron!!

Are there any nitrides formed? Does/will that increase wear resistance?

No nitrides were predicted at austenitizing temperatures. I'm not sure whether practically there would be primary nitrides formed during casting which would lead to them being retained at lower temperatures.

Thats for the info, Larrin. Either way, would the main benefit in a kitchen knife application be increased corrosion resistance at the expense of some abrasion resistance?

Yes.
Would their be any difference in the ability to take super fine, stable edge?

No, or at least not from a composition perspective. There can be differences in casting, forging, and annealing practices.
 
Just realized it's listed in your chart - sorry, Larrin! I suppose the question is still a relevant one, tough, although the answer is pretty clear..
 
Very interesting !.
If you look at the Sandvik knife steels they are fairly similar but with significant performance differences. .If the quality is maintained and extra steps need not be done by the custom maker it will be a hit. Certainly factories can benefit from it also.
Judging from the many questions about warpage problems , eliminating just that an you've got a hit.
Thanks Aldo !
 
The new stuff appears to have a couple of tenths more carbon. Maybe a little increase in potential hardness? I would jokingly say that the new Aldosteel will be a boon for dingalings who love really sharp edges can't take care of a regular stainless steel knives.;) But in all seriousness, this new stuff could be good for salt water knives. in addition to being good for kitchen knives for your sister-in-la who insist on putting them in the dishwasher. :eek: Okay,to be fair it was my niece. :p

My sister hid all of the knives I made for her family, as she us tired of washing everything by hand. If there was a dishwasher safe steel, I'd be all over it. Doesn't solve the problem of water and grit abrading a fine edge though.
 
Aldo,
That sounds like a Steel worth checking out!
I appreciate the heads up about the Wonky AEB-L out there. Fortunately I only purchase my steels from you or PMS...
 
On my knife that got washed, it was the handle that got messed up. Just so you know, even stabilized wood can "move" in the hot dishwasher.

I included 14C28N in the chart because the two are obviously similar, the biggest difference being chromium content. I wonder if the tiny amount of vanadium was added to avoid patent issues.
 
Larrin, I once had the project of making a steel where all the other steel makers had already made a version , each patented . So our alloy was made by just looking a place in the chart that would give the required performance . Crazy but true but it worked ! We metallurgists are strange !!
 
Be specific about whom you are referring to. You've posted serious accusations about your competitors. Post specific information rather than implicating everyone who sells AEB-L.

It has come to my attention that there is a load of AEB-L being sold that has both inclusions and some real bad stress problems causing it to bow significantly during heat treat. I was also told that waterjetters are having some really bad problems with knife blanks bowing up on there tables once they are cut, causing them to break off the carbide tips to the tune of 80 to 100 dollars per tip. This is typical of coiled steel that has been improperly flattened and more so this coil was probably the center of a larger coil which is the only explanation for why even a piece as short as a knife blank would pop up and break a carbide tip on a water jet. It is an issue we had early on before we added a cold roll process to our steels that all but eliminated the issue.

I want it to be known that this IS NOT OUR AEB-L and that if it was we would do whatever it took to remedy the problem. We sell the best damn knife steel we can get for all of you and take great pride in the fact that our complaint department is ME, and I take care of such issue's as promptly as possible when they come up.

Many of you have raved about our AEB-L and about our other steels as well. I am done with sitting back and taking the humble route while watching people get screwed over by steel suppliers who won't take responsibility for there own F@#*ups. Who ever is responsible for this CRAP that is circulating around, do the right thing, suck it up and replace it!

Salem, steels get rolled!! they also get straightened. it's the straightening and how it's done that makes the difference. When we first started processing our own bar the stuff was straightened on a stretcher. It didn't do so well. We have since added a skin pass. It is a cold roll process that seems to have helped a lot with that issue. We typically plate quench when we heat treat in my shop and don't have many problems. Most of our knives go out to Peter's. There stuff ready to grind .

Devin! Good to hear from you. We added .05 Vanadium and 1200PPM Nitrogen to the standing formula of .65c and 13.5Ch

We are still working out the details for 1.2519 which, if you look is very close to Blue#2 with added Chrome, but that's for another day.

Thanks for the info Aldo, looking forward to Blue #2 clone!

Increased corrosion resistance. It makes it more stainless.

So it would make AEBL possibly one of the most stain resistant metals.

Chuck: I highly doubt he's talking about you, the few pieces of AEBL I've gotten from you have been absolutely excellent
