@IAINMAN96 regular steel is used in survival and combat knives, because it is stronger and holds an edge better. Also, sharpening the edge would remove the antirust layer anyway
Cast steel is an alloy of iron and carbon below 2% of carbon in it. Steel itself is made by mechanical processing of cast steel (rolling, forging etc.)
But stainless steel sucks for swords, something about it being too expensive to harden properly. You need high carbon steel, and you have to oil it a lot, to prevent it from rusting.
hmmmm, professor the phallic nature of the mascot will be the main and probably only discussion ,but your innocent outlook on life warms a cynics heart .
@entoris476 Hi, I wouldn't say this was our definitive steel video, just something we did for fun when we heard about the mascots being made of steel... I expect we'll do more on steel soon.
The American mascot will be a donkey and an elephant which have been sewn together at the hips... All they'll be able to do is run around in circles while they yell at each other and stomp/kick an entire country into the ground.
nice video... more like this would be nice, but more complex and in depth ! as an engineer metallurgy has always interested me though, so perhaps i'm bias
Should add that iron's not really 'Soft," but brittle. It actually has quite a high surface hardness, and that (along with the roughness that typically comes in castings) is why it's hard to machine. That's why cast iron is used in car engines, even in aluminium blocks, it doesn't wear out quickly. Only a few engines (like the Nissan GT-R and some new ford engines) use different metals for cylinder liners, but these are coated in superheated iron plasma spray.
I love this channel and the odd characters in that lab. With a good script it could be a sit-com. Pete's love for burning booming things is fun to watch. They even have an Igor who almost never speaks.

Does it feel like he's patronizing all the nerds in the world in an attempt to get them into sports to anyone else?
With his crazy Einsteinian mad-scientist hair and half-baked attempts to incorporate science into the characters like "they're made out of steel" and "they have webcams for eyes"
Not gonna work, homie, when I want to see some weird creatures made out of steel having adventures, I'll just play Pokemon.
@MarlonOwnsYourCake No, not to me. It just feels like a bad pretext to try to segway into Steel. I do however agree that it should be dropped and just stick to the steel itself.
Still, I liked this video, as with all (or most at any rate) the periodic, sixtysymbols, etc videos.
@MarlonOwnsYourCake I highly doubt that his intention is to draw people to sports. I do believe that it's quite the opposite: He is using an event everyone in the world can recognize in order to draw more attention to science and chemistry. If you regularly watch the periodicvideo channel you will notice he does this often.
Wow you sure are a downer. He doesn't talk down to people and he didn't 'incorporate science into the characters' he is just pointing out the features that the Olympic committee chose.
@RectumPilum it is. zinc is used to coat a metal (usually aluminium) which protects it by providing both a physical barrier and an electronic barrier.
adding carbon to iron toughens it and gives it slightly different properties. When other metals are added, this gives stainless steel which doesnt rust. these metals are added whilst everything is still molten to form an alloy, not a coating such as galvanizing.
How about showing a follow-up video that talks about galvanized steel?
Great series, please make more.
