Yes, yes, yes! Im blacksmith and was trying to find a way for a long time to make my own alloy, but the forge cant reach the temperature to melt chromium or nickel. Now the problem is solved! Thank you soo much!

[@starchild7843]

Why does my forks and spoons and other cutlery rusts if I give them a quick soak even though it says stainless steel stamped on the underside of them? They are cheap, a dollar for 4 of them. I usually don't get these kind of cutlery, but I needed some after moving to a few states away from my home state and just left everything behind that I wouldn't be needing them and have more space for more important things. Either I would let relatives have the stuff I couldn't carry or not needed or donated stuff. So when I went to Walmart I was debating on getting plastic picnic ware or just go ahead and get the cheapest metal ones. The cheapest metal ones were the 4 pack for a dollar so I picked up two of the forks, 1 of the table 1 of the teaspoons. Brought them home cut the tape that was wrapped around them, stopped up or plugged up my kitchen sink and dropped them in some hot soapy water. The first soak and wash went well not rust but when I soaked again some rusted some didn't and I'm trying to figure out why they did when it says on the underside stainless steel? Why did some rust when I only soaked them about 5 mins. The 1st soak was longer about 30 mins to an hour. I used hot water the hottest water that could come out of the tap. You think it would of been that soak that done that but it was the 2nd 5min soak that done it in hot water but not as hot as the first one. So why did they rust? Sorry for it being long I was trying to making thorough as possible to understand it better. Thank you and have a wonderful and blessed day and stay safe! ✌🏼♥️😃

@@starchild7843 I am also a blacksmith, and I've actually made quite a bit of kitchenware from stainless steel. Despite its name, stainless steel can be rusted. The corrosion (rusting/tarnishing) resisting property of stainless steel is Chromium, and most stainless steel contains a fair amount of it, in some cases up to 14% Chromium. Though even with 14% Chromium, the iron is still susceptible to rusting, especially if left in a solution (soaking) for a long time. Unfortunately, I can't say for sure why your cutlery rusts, but I have a few ideas. The most likely is that the steel is simply just not of good quality. A stainless steel with a much lower Chromium content will still resist corrosion, but it will begin to rust fairly quickly if exposed to water over a long period of time. Alternatively, the water you're using could have something in it that induces rusting. I'm not too sure, but perhaps if your water is slightly too basic/acidic, it could erode past the surface layer Chromium. Hope this helped :)

[@DidNotKnowICouldDoThat]

There is a different more traditional way. That would be putting all the metals/elements in a crucible together with glass, sand and/or a kind of flux that doesn't produce gasses cealing it up and making a kind of furnus that can reach those temperatures. Like the one from the documentary secrets of the viking sword, where they try to recreate the ulfberht sword. Coal can burn up to 2000 C which should just be enough to melt chromium but a thermite reaction does burn hotter. The thing is that it takes some time to heat up and for everything to mix properly. They used to feed air into the furnus with bellows but now you can run an electric pump. Just make sure it displaces a large enough volume of air and can run for a long enough time. I've been wanting to do this myself but I don't have the space so I've been trying to find a place that will allow me to do this. Also a lot of stainless steels actually have a slightly lower melting point than regular steel. when you have molten the iron the chromium and other higher melting temperature elements will slowly dissolve in it which will change the melting point too.

@@starchild7843 On a boat out at the salty ocean stainless steel rust within a month... If you want something that do not rust at all you need Acid Resistant Steel.

[@illumiNOTme326]

@@starchild7843 stainless steel is very rust resistant but all of that goes out the window if it gets exposed to even microscopic rust particles from let's say a steel wool Brillo pad that was just used. If left on the surface all those tiny particles become nucleation points for rust to form and eat away the surface finish. Cleaning it with some sort of abrasive will remove the rust but the longer it continues to sit on the surface the deeper the pitting will be.

Now that was unexpected and very interesting, I follow a lot of blacksmiths and love the craft. I've also watched them smelt iron ore in homemade clay furnaces in the field to make cast iron, then hammer and fold it to get out the impurities. This is a whole new path, much easier IMO. I'd love to see some Blacksmiths try this process, and see the end results. Nicely done, and very educational. Thanks!

[@PBGetson]

Great idea. Please share this video with those blacksmith channels. I'd bet with enough of the viewers of those channels seeing this method, it might encourage a few of them to give this a try.

[@douglasboyle6544]

This was absolutely fascinating. I never thought about using the thermite redox to get the components in the alloy at the same time, so damn cool.

[@IAMZERG]

That's really neat! Didn't know you could use a thermite reaction to produce steel.

[@TheRealSykx]

oh ya that's one of the products of the thermite reaction: Fe2O3 + 2Al => Al2O3 + 2Fe when reacting it tends to fling molten iron around, so it's best to keep a safe distance

Excellent video as usual. I had no idea that a thermite reaction could be used to make alloys. I have made soft iron ingots using a kilo of thermite, but stainless steel is totally next level. A note for anyone trying this at home: Iron(III)oxide powder can cause serious eye damage and potentially irreversible damage to the digestive tract. Also the fumes can cause heavy-metal fever. Stay upwind!

Not loopholes, on the contraty he used chemistry at its finest

[@C-M-E]

This is surprisingly a more approachable version of how tamahagane has been made for hundreds of years, which the surprising part is more people don't use it. If you ever decide to do it again, I'd add a few pinches of Nickel in place or in addition to the Chromium, a dash of Manganese, and a pinch of Vanadium, then set it off with KMnO4 and a few drops of glycerin/glycerol. Then when you go to the forging process, folding the blade will remove impurities and close up the grain structure (reducing inclusions). The big inclusion on your blade will Definitely become a point of failure during heat treating. It's a bit more time consuming getting the amount right as you have to factor in shrinkage and forge losses, but if done correctly, you can cast thermite directly into a graphite mold like a billet or a larger version of your final product (ala sand casting with a graphite powdered barrier to prevent the steel sticking to the sand), then go to town on an anvil. I like to use the billet method as I'm going to fold it anyway for better grain structure.

[@ferrofeles2063]

the problem with thermite is that its not 100% iron usually its a combination of iron oxide and aluminum oxide beyond which can be added manganese etc but my point is shrinkage thermite shrinks quite a bit simply from the fact that all of the air gaps got burned out not to mention that the aluminum oxide would burn off to slag leaving you pretty pure iron getting steel out of the process is frankly fascinating

Hardness test was performed without sufficient support, measured value of 200 Hardness Leeb D scale is indicating wrong measurement- annealed steel has ~500 HLD, thus any piece of steel You may find and measure will have at least 500 HLD. For example, hammer head should have at least 700 HLD. To achieve proper reading, support knife blade on a heavy( couple kg) flat steel piece, store-bought kitchen knife will have at least 700 HLD~= 50 HRC.

Excellent! Thermite is so versatile, and you can do so much with the process. It is a wonder that it isn't shown to be one of the earliest ways to make iron and other alloys of iron. Bauxite and iron oxide works as good as aluminum powder to make thermite.

[@Markle2k]

Bauxite already has oxygen attached. How is it going to steal oxygen from the iron and other oxides?

[@HenriFaust]

Aluminum requires large amounts of electricity to be extracted from bauxite.

@@HenriFaust No, it requires heat, which we use electricity to produce with carbon rods in the bauxite. The excess oxygen reacts with the carbon rods to produce MASSIVE amounts of carbon dioxide gas and liquid aluminum.

Either way keep it up Estonia, the more Estonians that become popular in around the world the more the people from other nations will support Estonia and force their governments to take action if Russia decides to go full Soviet Union.

Quenching is different from tempering. Quenching reduces the temperature dramatically thus increasing hardness and tempering is a gradual heating process to remove excess strain in the metal increasing toughness.

Why does steel that was made is the early days so much more corrosion resistance than metal made today ?? The rust color is much redder than the old steel color of light red. Also, the corrosion stops when the surface is lightly rusted. What is causing this to happen Thoisoi2.

[@StodOneR]

To start blacksmithing you only need 3 basic things Something to heat the steel with , something to hit the steel with and something to brace the steel against. So you can use a railroad for anvil , regular hammer and even a simple hardwood with some air supply would heat the steel enough to forge . In this case though you would need something to hold the steel with since it's small .
