hi guys,i mainly use 1095 steel for making my knives,i came across a LN dewar for free and was wondering it there would be any benefit in freezing this steel type and if so what would be the best way to do it and for how long,thanks

According to all the Wiz Bang stuff out there it only works on SS
BS I say always adds 2-3RC pts when I do it
 
hey blinker,ive also heard that too,but my guess would be that it'll improve any type of steel,guess it wont hurt to try
 
It will help most steels, carbon or stainless. The only steels I know of that it doesn't make a noticeable difference are some of the CPM steels, due to their already ultra fine grain and high percentaqe tranformation to martensite.

I used to have it done to my 52100, and it definately improved the steel.
 
So we can aply the same crio techniques used on SS to carbon and expect some improvent in grain and hardness? Cool.
 
Well, it's certainly not going to hurt your blades, so why not get it?
 
ok guys i had it sent off today to have it filled,i have a buddy that works for a welding supply house and it wont cost me hardly anything,when i get it back how long should i leave my blades in the dewar?

works for most of the high-carbon steels. 1095 benefits from even a night-stay in the freezer. Ed Fowler "freezes" his 52100. 5160 also works in it.

If it's free...why not try it out, right?



(yes...I am having jealousy pain :p)
 
I have heard a lot on this subject and have not done it myself. Reason being I can't do it myself. If I had one I would for sure experiment with it for I think from all I have heard and read it will help.

From what I have found with 5160 and 52100 if LN freezing makes a lot of difference in performance you can make up the deficit by working on forging and heat treating methods.
