Q:Heat treatment of mild steel? Process description macro-micro
Alright, usually whu heat you heat treat mild steel, this is because you would like it stronger than you got it. To do this you must alter the grain structure of the part or in other words, the CRYSTALLITES. Ultimately you'll end up altering the nature of the grains structure changing the tensile strength it can handle, yield strength, and even change the elongation percentage that it can tolerate under load. Heat treatment controls the rate of diffusion, and the rate of cooling within the microstructure to create these elements. Usually what they use to do this is add an element to it to make it stronger such as carbon to increase its rockwell hardness, which by the way the lower you go the harder the part can become. Heat treatment can be used in more ways than this. It can also be used to weaken the parts grain structure. This will lower the parts mechanical properties making it softer and more ductile or easier to manipulate if you have to bend it into a particular shape. Typically if you allow the part to cool after heat treatment it does go through annealing. The part will be heat treated into different stages. The first being the austenitic crystal phase which depending on how hard and strong you want it, will be at its peak. When it is cooled, it will go through a will transform to martensite which is a hard yet brittle crystalline structure. Martenised part will usually be tempered to a certain degree to improve the mechanical properties to what is needed. There is more to this and you can use the link below to read more about it.
Q:what can i do to polish steel or iron?
Look for buffing compound at the hardware store. Home depot lowe's od even Wal-mart/ There is a compound for steel and for iron. I t will not make iron real shinny but it will make it look good. This stuff is to be used with a buffing wheel but I have used it on rags and it work great.
Q:strongest steel ever made?
Wootz is laughable. A modern car spring has more tensile strength, not to mention better purity in manufacturing. Alpha B is right. My answer would be NS110. While wootz was the source of the original damascus steel. The manufacturing process was much like many crucible type steels of the past. And they were not used by japanese smiths. A traditional japanese sword was made from the ground up. Smelting the iron laden sand into Tamahagane. Which is a pumice like crude steel. It would be forged, and diamond powder would be applied and hammered into the skin. It would then be folded repeatedly to homogenize the blade. For what you are asking for now. I would say that 1/2 mild steel plate should work nicely.
Q:knowledge of steel composition?
You have opened a can of worms. Specific types of steel vary not only by composition but by the way they were made, their physical properties and their morphology (microscopic structure). The composition you have given would fit for High Carbon Steel and Medium Carbon Steel. Go to the reference I've given, it allows you to put in 3 of the components of your alloy and then it gives you a list of possibilities. You can open each candidate individually and see the full composition. Hours of fun. :)
Q:How to temper steel? ?
Heat treating easy, HA! It is the most critical part of bladesmithing. Done wrong and all those hours of work go up in smoke (or a snap of the steel). You'll need a bucket of oil, preferably one that is deep enough to go in point first. If not you'll have to go in edge first, not recommended on a double edged blade, ok for single edge. You'll need to build a charcoal fire long enough for the blade. You will need to blow air under the fire to get it hot enough, the challenge is getting the heat even. You get the fire going and established, put the blade in turning it back and forth (if you keep turning it in the same direction when it heats up you could work a twist in it). When it starts turning red pull it out and touch it with a magnet, if the magnet sticks put it back. Keep heating and repeating until the magnet no longer sticks. Heat a little more, then quench rapidly point first. Don't let the blade lean to one side as warpage will occur. When it cools enough to touch, check with a file. If the doesn't file cut then you've properly hardened the steel and it's ready for temper. Now comes the really hard part. Grind the scale off carefully,preferably with a side grinder with a flap wheel. I've had hard wheel break freshly hardened blades. After cleaning you'll need to put it in an oven (preferred) or use a torch and carefully heat the blade. Watch the temper colors (oven temp 500-550F) or with the torch as the steel turns colors blue to purple for a double edged weapon. Any warpage that occurs needs to be worked out at temping temp.
Q:How does Steel help us in society?
steel comes from iron. Iron is a natural resource and is abundent in nature. so being able to turn it into steel means it can be used for alllll sorts of things! from buildings, cars, piping and tubes, to washing machines, appliances and many other things. its used in our everyday life and is a great, strong material.
Q:where did WTC steel go?
Some of the steel was recycled for sale to other countries where they aren't so picky about reusing building materials. NIST had 200 pieces of the steel for their investigation, which they returned last year. This was covered in the press. The rest of the steel was held at JFK international airport's Hangar 17. Much of it will be placed/has been placed in the new museum beneath the Memorial at the WTC site. Thousands of pieces are being given out for 9/11 memorials all over the world. Just about every day you read in the newspaper about another piece going here or there to this city or that city. Yes, a lot of the steel was tested for a number of chemical compounds. It had to be for safety reasons before storing it and giving it out. Depending upon what countries the recycled beams were sent to and their rules, it was sometimes tested at the ports of entry over there, as well.
Q:whats the difference between weld steel and sheet metal?
Most sheet metal is coated with galvanizing. Not fun to weld on. Most steel for welding use is just carbon steel.
Q:Would aftermarket steel wheels weigh more than stock jeep wheels?
steel is steel is steel- they will always be heavy you would have to weigh them to find out--NOW if you are going to alloy wheels they are typically aluminum and yes they are lighter -this is good because it lightens your un-sprung weight and is less harmful to your suspension-good for your auto
