Cerakote mess up Temper?

[Army of Nobunaga]

Hey guys, I did a search and did not see this topic. And I figured you knife makers would know the answer.

A buddy and me are thinking about getting some of our high carbon large knives Cerakoted.

My question is will the 350f mess up the temper in any way?

Thanks in advance.

It would help if you specified the steel that you were using. That may or may not make a difference.

I dont know the time in the oven for the Cerakote.


Thanks man.

Here are data sheets on all 3 knives.

Army ....

Your question has a few variables involved, Most High Carbon steel knives (That I do anyway) are tempered in the 350 - 400 F. Range. I wouldn't go over 350, and who knows their process and how steady / stable there heat is? Time at a temp is not a problem, Temp is everything.

I assume you don't have handle material on them?

Yes the knives we were thinking about doing, we can take the handles off. I was afraid that 350 might be too close to the temper level. The guy that does it says his oven is a steady 350.

Is there a way for a layman to check temper? If so we could do a trial knife and see what happens. Sorry if my questions are dumb... Metal working and propertys are a new field for me.

Don't worry about it, The cerakote won't affect the temper.

And, no, you can't check to tell what the tempering temperature was. All you can do is test the edge and see if it chips or rolls. If it is not either of those, it is a good temper .
For most blade steels, the temper range is 400-450F. Many makers temper at 350F, but that is usually a bit too low for any blade but a kitchen slicer. The edge will usually last longer with a slightly higher temper. The amount of drop in hardness is almost nothing between a 350 temper and a 400 temper, but the edge is tougher.

First off..why is this coater curing at 350!! 250 all day long is the perfect temp...300 at most. At those temps I have never had a issue with messing up the temper of anything.

Thanks guys, I will find another coater and compare temps and prices, Ill post pictures and results of the first one.

Cerakote instructions are 250 for two hours or 300 for 45 minutes.

Depending on the color and the item that is in the oven that is correct....I know curing temps for different colors and different items being coated as that is what I do for a living.
