Toaster oven for tempering?

7 Temper Blade. Heat an oven to F. Clean off the quenching oil and put the blade in the oven for 30 minutes. Let it air cool. Repeat this cycle three times. Tempering will slightly reduce the hardness of your knife. But the knife will have added toughness and therefore be stronger overall. Next. Tempering makes the knife A Bit Softer and a Lot Tougher. Heat treating your knife hardens it significantly, but also makes it brittle like glasssusceptible to cracks and breaks if dropped. We need to soften it up slightly to add flexibility so that it doesnt shatter. Were trying to achieve a Rockwell Hardeness of somewhere between This step should be carried out soon after heat treating, .

Given that I lack a specialized tempering oven, I was wondering if it is possible to temper blade steel I'm using currently in either a kitchen oven or a grill. I really don't have the money to buy a tempering oven, which is why I'm asking this question in the first place yes Steve, before you chastise me rather than answer this question, I did look for a similar question and couldn't find anything.

There is, however, a problem that I see with using the oven: It is in a kitchen, and my forge is outside, so I'll also ask how long does in take a quenched, untempered steel blade to crack after the quench? Perhaps if I move this post to the blade heat treating section I can't answer your specific question, but I can offer a piece of time-tested advice: If you quench in any oil other than canola, do not temper in your kitchen oven.

Unless you have a solid exhaust system and a good divorce lawyer. It would be relatively easy to get it up to the temperatures mentioned in the "Advanced Heat Treating" post, and it's outside and can be warmed up quickly, so yeah, may not need to use the oven. How long does it take for something I drop to hit the ground? Like your question, very indeterminate.

The best answer is to move quickly from the quench to the tempering. You can buy "toaster ovens" for a reasonable price if your rdw cv low what does it mean are normal knife blade sizes, one of those might do the job for you.

If you normalize during the forging and again before you harden you shouldn't have problems. I let ten-hundred series steels cool to room temp after quenching and wire brush the scale and oil completely off the blades before tempering whether I'm using an oven or drawing heat from a sacrificial piece of steel to watch the colors run and temper by eye. Toaster ovens tend to have big heat swings but you can compensate for that somewhat by going on the high end of the heat range.

Most toaster ovens don't go over f. Start with your temper cycles at max heat for your toaster oven and then see if a file skates on the how to replace electrical box. If the file cuts your what is an ms flare up easily you can re-harden and try again at lower heat.

Bottom line, without precision equipment you won't get precision, predictable results without some trial and error. You can get good, repeatable results by keeping notes, only changing one thing at a time on each run through and doing it exactly the same way once you get the desired results. I've never even thought of using a gas grill but if you have one with a thermostat try it and see what works.

You could also stack fire bricks inside your gas grill to make an insulated chamber, an oven in an oven. Place a second temperature probe inside your brick pile so you know exactly what's going on in the inner chamber and see if you can find a grill setting that holds that inner chamber steady at a desired temp.

This has probably been mentioned a bazillion times before, but warrants mentioning again I use our electric oven and put an oven thermometer in it. Our oven is actually about degrees hotter than the temp setting.

No problem front to back how to get wife to lose weight a single pan; I just pulled them as they were done. Gave two loaves to my daughter as a house warming gift and ate the other one myself I got lucky there, ours is a convection oven to boot, so the circulation is better than none.

Yes, I do put the thermometer where I place the work. You can post now and register later. If you have an account, sign in now to post with your account. Paste as plain text instead.
