Steel Metallurgy - Principles of Metallurgy

Steel is the widest used metal, in this video we look at what constitutes a steel, what properties can be effected, what chemical elements we add to steel and how these effect the properties.

i learn more from this video about metallurgy than 6 months of school when it comes to metallurgy, and the properties of the different alloying component.

It's rare to find a video so thorough when it comes to alloys, thanks

I’m a Metallurgical Technician going to an interview tomorrow morning. This good stuff. I was looking for a review. I’ve only got the one course on Metallurgy they teach in Oregon and three years experience in a Met Lab. It’s been a year and eight months since a large cutback cost me the best job I ever had. This is stuff I’m familiar with, but this video is great. Just what I was looking for. 👍

[@krzykris]

I hope the interview went well! Did you work in steel in Oregon?

[@user-ms5hn1td4n]

Simplified and straightforward. Thanks very much

[@laernulienlaernulienlaernu8953]

It's amazing how many different variations of steel there is, just by adding different elements in varying amounts and by how it's heated and cooled.

[@TOUGHEYES]

This is the groundwork and fundamental, material principles that determined the innovation and foundation of our civilisation. And here I am, motivated to look into this subject at length solely to make perfect Greatswords that cannot be lifted by normal men or broken/corroded, or legendary style weapons that goes into a culture's mythology they're so awesome/scary.

wow, thank you so much, i am currently studying , i am an apprentice tool maker, and so far the information supplied via my course has been extremely hard to grasp. when you see the graphs and read the words its not enough to understand how to read the graph its self . This video made so much sense. it really made everything i have been reading click into place, especially the graphs. thanks to this video it all fell into place. thank you so much. i have been struggling to understand this. and now i see how simple it all is. i really appreciate the effort you have made to explain this heat treatment system. thanks again .

Sulphur combines with manganese to form MnS (manganese sulphide). This MnS combines and forms slag. It is than removed by de-slagging process thus lowering the content of Sulphur in steel/austenitic manganese steel.

theres this thing called taking notes, i dont know if you've heard of it before but it works great

[@zachattacking]

Why not take a screenshot for every step in the explanation?

[@artinveins2281]

Manganese is combined with sulphur to prevent hot shortness??? Pls explain...

[@kiritibhattacharya2772]

If sulphur is allowed to remain in steels, hot shortness results, meaning you would have non-metallic brittle phase between the ductile iron grains...no good. So we add Mn. This now combines with the sulphur, forms MnS which does not form the brittle network at the grain boundaries. Hope this helps.

[@DanielVeja.]

Hot shortness in kind of innacurate. Hot embrittlement is more accurate. It means growing the temperature at which steels become brittle (eg.: if a steel usually embrittles at -20C, if it has a high sulphur content (~0.5% or more) it could embrittle at -10C). When we add Mn, it forms MnS (in combination with S) and this (partially) eliminates hot embrittlement.

[@canesvenatici9588]

So basically Sulphur is a bad impurity to be in your steel that leads to brittleness especially in low temperature but we can still counter it without trying so hard purifying it by adding Manganese? am I right?

How does the SS retain austenite phase at room temperature when below 723deg austenite does not exist ? Do you mean you heat to above 723deg and quench it to retain its austenite phase ?????

What about temperature

[@pekkolainen]

nice vid. some small "faults". for ex. chromium used in stainless steel? chromium is what makes it stainless steel :) *used in steel to make stainless steel.

[@flamingfrancis]

That is not a "fault" in any way. In the manufacturing of raw stainless steel Ferro Chromium is often added to the melt in the process. As a rule stainless scrap with approximately the required content for the elevant specification, is used in the charge. As a techno person who worked with many, many specifications including most stainless grades for over four decades I can vouch for much of the info contained herein.

[@davidcarter5813]

This is the kind of teaching that should be done in a Metallurgical Engineering curriculum, but it's not. Instead they go deeply into dislocation theory and crystallographic transformations in a way that will only be useful in a research position. A Bachelors degree in this field is now useless. Don't even bother.
