well yes it strain hardens,for an instance if you take an annealed copper rod and bend it,it would bend quite easily but if you try to bring back the original shape,you wouldn't be able to do it with your bare hands....simple explaination is that its due to work hardening property,same is with ss304
Hi, I believe you are referring to the 4 blocks holding up the fiber board (also know as a kiln shelf). These are two pieces of our magnesia soldering blocks cut in half. Here is a link to this product: www.cooltools.us/ProductDetails.asp?ProductCode=SOL-407 Thank you for your question!
Hi Molly, copper rod is used in this video. For all of the products used, click the link below and they will all be listed: www.cooltools.us/Annealing-Metal-s/1775.htm Thanks for watching!

Annealing is a heat treatment that increase ductility which makes the metal more workable.
This comment could of saved me about 2 hours of useless videos that drag on explanation
thank you, but why you guys differentiate ferrous & non ferrous metals?
Does working with the metal after annealing, cause it to harden once again? how many times can you anneal a piece while you are working with it?

Plz say about it's temperature
Hi, you will just want to heat your metal until it glows. Because a torch is being used, there is no specific temperature to state. Hope this helps!
effective keep it up THANKU 4 PRESENTATION
👍👍
thanks! I'm studying introduction to materials science and this helped me understand annealing.. exams are close cheers!
same here :)
Very informative video for mechanical engineers
What us meant by the critical temperature we are using here?
Could you please explain?

thats so cool man, thank you for you awesome explanation
instructive :D
Thanks helped with my DT hw for school
Why do you not quench? I was taught to quench to maximize softening.
Quenching hardens the steel
thanks a lot but i have a doubt
what did you use to torch the metal piece?
Hello, an acetylene torch is used to torch the metal. Thanks for watching!
@@cooltoolsvideos thanks a lot
Love Cool Tools Videos.
it is simple and straight forward.
0:20
What is the difference between Tempering and Annealing. Plz tell!!! My exams r upcoming!!!!
Why is this video interlaced?
Ok but how will heating a bar of metal help with my internal stress
hi what kind of flame is that? neutral or carbonising?
1:50 is what you're looking for..
The video cut at 2:40 freaked me out watching him pickup the glowing rod 😅
Super interesting demonstration!
Thanks bro
Oh neil
Whats the white thing u used as stand...???

Thanks for watching!
how much temperature required for annealing?
Hello, you want to heat the metal until there is a dull red glow on across the whole piece of metal. Hope this helps!
About 30 to 40 Deg.C, above the upper critical temperature range of the metal.
@@benalexandre4423 what's the meaning of critical temperature ?
