Thread: This ATP high temperature coating works great

Bruno, I think what Pat is saying is that he can finish his post HT grinding on the blade at 320 grit so the finish sanding on the blade is no different that not using the high temp mask. Where it saves him sanding hardened steel is on the tang.

Hey Pat,☺

So your doing the rough grinding, including the shaping and tapering of the tang.
The razor now has a preliminary hollow grind.
How much of the razor is being coated?
All? If you are applying the ATP to the entire razor does that interfere with the heat treat?
I understand the desire to minimize the damage done to the surface of the razor from heat treating and tempering.

The razor pre coating is complete except for final grind on hollow at this point all I need to grind is the hollow it is .050 I finish the hollow and then do clean up sanding only.

Thanks. Now I understand what you meant.

ATP 304 or ATP 504 ?

I use the ATP-641

I coat the whole blade does not interfere with heat treat now I just finish grind the blade down to 15 micron belts and buff all done.

Thanks Pat

Ah ok. In that case I understand.
I found that heating in an iron pipe also prevents the formation of heat damage.

I do the same, but in a gas forge. I also put a piece of charcoal in the end of the pipe to keep a reducing atmosphere in the pipe. I get no scale at all.

Caution: Do not try the charcoal trick in an oven as CO is a fuel and could cause an explosion!
