SAE-AISI carbon and alloy steel designation numbers explained and visualized.
My last Fe amount should read 98.5kg.

So important to have a basic idea of steel compounds, its no good taking the time and effort to fabricate something only for it to fail by being not fit for purpose because the right type of steel wasn't used, ie tensile strength, hardness, ductility, wear resistance ect. It brings it home to think of a 50kg or hundred weight sack of coal as compared to the minute amount of carbon required to change it from low carbon to high carbon steel. Anyway enough of me harping on, i just want to say brilliant and easy to understand video. Thank you so much.

Do you have a link for where you pulled those material spec sheets?

Very very useful. Thank you sir. I have always wanted to learn about this. I am in steel business (family business) . But i inow nothing about steel content. I did not study mettallurgy at university. I feel regret all the time. Now your video give me light. Thank you for sharing it. May your business be always successful.

Boy that was harsh, u can still do it tho, I mean the university part.

You can watch metallurgy related videos at nptel youtube channel. It has all University level subject courses for metallurgy and other engineering branches.

Can u please elaborate on EN steels. I'm not getting which designation system used for grade EN1A

I have US drawing and the base material is : "material - 9531476; opt. material - 8493933". The SAE/AISI material grade codes are 4 digits. how do I decode these nombers?

@theoverengineer Жыл бұрын

That's difficult, the 'product code' MAY or MAY NOT have the SAE digits in them "1476" and "3933". Tricky, this one. Thanks for watching!

so what does the 10 in 1080 steel refer to?

That it's steel (aluminum alloys start with 2, 3, 4, 5, 6, 7)

What is the difference in physical properties between 4150 and 4140 steel. For example, wear resistance, ductility, hardness etc.

First numbers the metal it's made of ... 4 is molybdenum.. the second number is impurities ( weld rods 6010/7010/7018,very clean to avoid viscosity) 1 I think is lead ... last 2 numbers are carbon compounds making it harder So 4140 is softer than 4160 but same steel

Matthew Denty Could u be more simple? As simple as ur telling to an animal to understand, such as me :/
