For some reasion I want to start a heat treat oven thread now lol

Shoot @JTknives ......start with Evenheat commercial oven......... ± temperature uniformity inside oven , what kind of protection have this oven from overheating by direct radiant heat ....etc
After that you can give us specification of your home made HT oven , again what kind +/- heat uniformity you have , what kind of protection from overheating you have ....You know that when the heat elements are ON they radiate far more heat then that 1475f @Wille71 want.
Lets see that when @Willie71 set temp. on 1475f ..... have 1475 heated blade inside !

Just a quick update. 1084, 1095, 52100, and O1 with standard heat treat are done. I did all of them at 1475f,10 min soak. Tempered in 50f increments from either 300-450f, or 350-500f. I’m going to do more O1 and 52100 with a 1550f soak, cryo, and then temper for comparison. I might do 1095 and W2 like that as well.

This guy should be banned.

This is not a friendly thread about heat treating, it is personal attacks on some of our best members who actually contribute positively to the forum.

Nutlek does not have a furnace nor does he do any heat treating. He does think that he knows everything about the subject however, from reading the internet.

There are many advantages to small shop heat treating. Blades heat up faster, blades move from furnace to quench faster, blades cool off faster, blades move to cryo faster etc.

Blades are not grouped with steels from several different melts hoping to get a similar outcome. They are not heat treated with steels that have overlapping heat treat schedules. More control is given to each blade. Rockwell hardness is not a very good indicator of an optimum heat treat, it’s only part of it.

I could go on and on.

Trying to elevate youself as a knifemaker by tearing others down should be cause to be banned.

This is spillover from another thread where he claims that you can’t do quality heat treating in a small shop. He also included some personal attacks on Larrin and others.

Nutlek has made very few knives yet interjects into lots if threads.

That s simple not try ! I don t claim that you can not HT steel in that kind of oven! I claim that TEST would not be 100 % Valid because of inaccuracy of that kind of oven ! Do you want to see to what kind of oven I have access ?

Banned ?? For what my friend ? For opening thread to discuss pros/cons of commercial HT ovens ? If you don t like this thread .......:D

Are you finish with complaints ? Personal attack ? Interject into lots of thread ? Where is that thread where I interject and what I done wrong in that thread that you don t like ?????
Maybe it is my English...but my intention there was just to point that for that kind of test is important to have a little better HT oven then commercial one if you want to get reliable data from all that hard work .

More trolling.
 
So , did anyone measured temp. in different place in oven ?
Because ...........
Temperature uniformity is one of the most important technical indexes in heat treatment furnace, which relates directly to final performance of heat treatment products

Natlek,
This thread is nonsense. I would like to think it was the result of a night of heavy drinking.

I am closing this thread. I have noticed lately you have mostly posted that your methods are better than those who have years of experience. I don't really know your abilities, but the posts lately are purely argumentative. We don't need that.

Please post photos of your build projects and the knives you make. Leave these arguments out or I'll have to deal with it.
