How many companies do you know that temper in oil, lead, or salt baths? Normal atmosphere tempering is the most common probably followed by vacuum tempering. Those liquid baths are primarily used for martempering (not the same process as tempering), austempering (also not the same process as tempering) or differential hardening. Also the normalization time cited in this video is true for blacksmiths and knife makers, industrial normalizing of forgings often requires hold times on the order of hours not tens of minutes.

Thanks from indonesia

Very educative

Thanks for the videos sir.The videos are so much helpful to understand the metallurgy concepts.

what about xnxx?

Good stuff!

Awesome! Thanks for sharing!

Nice. Makes more sense with the making of a knife

I like this AI voice, could you share it pls?

You can bet they' re making pizza in the furnace when the boss is not there

Hello good afternoon Can you please give us a lecture on stages of heat treatment

Interesting indeed

Thank you 👍

The increasing use of hydroxyapatite in implants would probably warrant inclusion in the video.

Thank you for the Informative video presentation. This makes easy to understand learn for people who are getting into maintain their own homes or trying to find not only construction company but know what materials they want for their house.

Very informative.thanks sir

If only we had resources like this thirty years ago when I was doing my Mech Eng degree, I might have finished up with a decent overview of the field instead of general frustration & bewilderment.

James, as in shitasian? right?

valid

Everyone forgets that this " clean alternative " is powered by the burning of fossil fuels and/or fisionable materials...😅

Dr : can you send your email

What's your measurements to water

Hello from Turkey. The critical cooling rate used in the field of heat treatment is related to hardenability. If the TTT diagram of a steel is close to the right side, a high hardness microstructure can be achieved even at slower critical cooling rates. This depends completely on the chemical composition of the steels (%C, %Ni,%Mo,%Mn,%Cr)

where is intergranular corrosion??

Extremely useful and informative! Thank you!!

Been doing this shit 8 years and didn’t know half the shit this dude talked about haha

Very good information. The AI voice over always distracts me though

Thank you sir ❤❤❤ From India ❤❤

Anyone know what the name of the machine at 4:01 is? The pressure forming one that spins.

Thank you for taking the time to create this video. It was very useful.

Nice

Really helpful! Thank you 🙏🏻

The bed height depends on both the diameter of the cupola bore and the blast pressure. It may or may not be 40 inches. Also, with the advantages of a cupola listed at the end, you forgot two of the most important. They are FAST. Many times faster than a large crucible type furnace. And they are continuous melters, dropping charge after charge as long as layers of metal and replacement fuel are added at the top.

What I really want to know is the difference between broiling and grilling. Maybe even the differences between braising and broiling, too. Nevermind roasting.

The purpose of roasting is removing sulfur from the ore. Hot air converts solid sulfide to gaseous oxide.

Thank you. This is informative.

I wish to highlight the difference between a "transmitter" and a "switch".

Vanadium is missing

Thank you.

Thank you very much for this informative video!

Seu conteúdo é muito bom. Há 40 anos minha cidade era uma terra de produtores de ferro e aço, de fundições e forjarias e toda cadeia relaciona a produção, na cidade vizinha temos uma jazida de minério ferro. A produção de minério continua em expansão, as siderurgias diminuiram de número mas se sofisticaram. Por isto aprecio tanto o seu conteúdo. Saudações de Minas Gerais State, Brasil.

Most experts call grains crystallites. The smaller the crystallites, the stronger the alloy. Elongated crystallites make stronger alloy than spherical crystallites.

Great video sir. Thank you!

Hi. Thanks for your video. I am looking for the source documentation regarding your chart listing the various mix especially for Grade 30,35 and 40 concrete. Thanks.
