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’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?

[@LegendLength]

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

[@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.

[@AquaMarine1000]

A 100% pearlite structure is at 0.83 carbon. This video takes me back fifty years when I studied the subject.

[@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.

[@abhishekjaiswal1321]

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.

[@Toxictheory416]

Question I have some material with Cr .50 Ni 3.5 and Cu 1.25 but can't find a grade for it anyone know?

[@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?

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.

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.

What Quran the book of living miracles written 1500 years back, talks about Iron ? Why the verse of Book and The Balance (Constitution/Law/Legislation) talks of Iron ?? What Equality for all, in resources / status / society, had to do with steel / Iron ??? Note the naming of Chapter and Verse 57:26 the atomic Wt and atomic No of Iron???? لَقَدْ أَرْسَلْنَا رُسُلَنَا بِالْبَيِّنَاتِ وَأَنزَلْنَا مَعَهُمُ الْكِتَابَ وَالْمِيزَانَ لِيَقُومَ النَّاسُ بِالْقِسْطِ وَأَنزَلْنَا الْحَدِيدَ فِيهِ بَأْسٌ شَدِيدٌ وَمَنَافِعُ لِلنَّاسِ وَلِيَعْلَمَ اللَّـهُ مَن يَنصُرُهُ وَرُسُلَهُ بِالْغَيْبِ إِنَّ اللَّـهَ قَوِيٌّ عَزِيزٌ ﴿الحديد: ٢٥﴾ Most certainly, We have send our Messengers with signs and send with them “The Book and The Balance” (Constitution/Law/Legislation) to establish equality / justice among men. And We sent down ““Iron”” (on purpose). In Iron, are great-powers (hard steel for structures) and diverse specification (magnetism and current) for men. And Allah knows, who helps Him and His messenger “unseen” Verily Allah is in Himself, most mighty and most Powerful. 57:26. Now connect the verse, to understand unseen power of Iron and how it helps to propagate the Message of Allah ? Signs Balance Iron Power Uses Helping unseen (science) (Gravity) (Magnetism) (electricity) (Current Uses) (Dawa on social media) The Greatest Science in this verse of Quran is “”We sent Iron””...... Iron was not the produce of planet earth at the time of its birth,,, as water. Iron was sent to earth after millions of years of its creation / birth. and then water was sent......2:27 We know now by science Iron is not the product of earth but it came to earth by meteorites when planet earth was still in volcanic stage. Then came the water to cool the earth and start life. Why Iron was sent first and Water next ? Iron formed the gravity and held the water vapors from flying off back in space. This information was unknown at the time of revelation and was discovered by scientist few years back..... THEN HOW DOES QURAN MENTIONS THIS.???? This authenticates / confirms / Certifies Quran is a Divine book A PARALLEL BOOK WITH SCIENCE.... Whereas Bible .....it starts with first fake sentence Genesis 1 First earth for Formless, Dark and Dark oceans Then God created light And God saw light was good ......bla bla bla So with this verse, Quran discloses great secrets of creation procedure of planet earth Lets science and see points wise: 1) First earth was Dry, Hot, Volcanic and Lava filled 18:45 / 6:59 / 22:5. 2) First earth was Gravity-less, so no atmosphere.57:25 3) No atmosphere means, water oxygen cannot stay on earth. 4) Iron should be sent in lava earth period, where it buried in depth of earth necessary. 5) Quantity of Iron sent should establish, proper Gravity to hold atmosphere and support life. 6) After atmosphere, it was time of Water to cool earth and start Sea, Oceans, and Rivers because of Gravity. 7) After water and rivers plants and first single cell life because of Gravity 2:27 All this, “then unknown secrets” are enclosed in this simple verse of Quran certifying that Creator of universe knows its secrets billion of years back. This is how Quran talks in short sentences or telegram messages.

Meteoric Iron was the only form used by ancient humans as it was found on the surface and we didn't understand how to obtain iron from ore yet. However, iron ore is quite common on Earth and the core of our planet is composed of Iron. I guess those verses illustrate the ignorance of early man.
