Q:Guitar strings, nylon or steel?
Your steel-string acoustic should not be all that much harder to play than your nylon string acoustic. Classical guitars have stretchier strings, but they also normally have higher action (string height). It sounds like your steel-string may have a problem. A typical low action would be around 0.090 gap between the low E string and the top of the 12th fret, and 0.070 between the high E and the top of the 12th fret. If yours is a lot higher than that, having it professionally set up will probably help. If it's a very cheap guitar, replacement might be the best option. Why do you need to choose between classical and steel-string? You already own both.
Q:how carbon is being alloyed during steel making?
It's not really that hard. You can use your charcoal grill to do it. First build a large fire in it and then bury the steel in the coals. It'll only take about ten minuites or so for the steel to heat through. Then pick it out of the coals with tongs and drop it into a bucket of water. Repeat as desired. Eventually it'll get as brittle as glass. To fix this, you must anneal the metal. Again heat the metal in the coals, only this time let it stay there until the coals go all the way out all by themselves. Next day when all the way cool, Take it out and clean it off. Viola!, you have hardened steel.
Welding austenitic stainless steels to carbon and low alloy steels are established methods in the process and construction industries. Dissimilar metal welds involving stainless steels can be done using most full fusion weld methods, including TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas). Weld procedures using filler (consumable) enable better control of joint corrosion resistance and mechanical properties. In selecting the weld filler, the joint is considered as being stainless, rather than the carbon steel. Over-alloyed fillers are used to avoid dilution of the alloying elements in the fusion zone of the parent stainless steel.
Q:what is the elastic limit of steel in Nm^2?
It depends on the type of steel and how the wire was made (e.g. whether it was drawn hot or cold, whether it was heat treated after it was drawn, etc). For mild steel the elastic limit is about 400 MPa. Note this is not the same as the breaking stress for the wire which will typically be significantly higher for a ductile material like steel. If you want to measure a stress-strain curve to find youngs modulus, make sure you measure several points at stresses below the elastic limit - for example try increasing the stress in increments of about 50 MPa.
Q:Steel Strings or Nylons?
Kind of a silly question. I use steel strings on my steel string guitars and nylon strings on my classical guitar. It's not something you have any choice in; steel string guitars must use steel strings and classical guitar must use nylon strings.
Q:What is the difference between a steel strip and a coil? The steel strip is flat steel, and the steel coil is made of steel.
A steel strip is a steel strip of relative range, and can be called a steel strip when the width is less than 1000.
Q:steel plow?
If you're willing to substitute the word iron for steel (steel came a good bit later in history), the Girard plow from the 1300's in Belgium would be the first example known. It's named after the guy who invented it (Girard). How did it work? Like any other plow! You drag it along and it makes a trench of sorts in the ground! It was used for agricultural purposes. As for how it was produced, you need to look up the history of the Iron Age to understand how they started to use iron back in about 1200BC to make tools.

Q:how to make a unique piece of steel?
If you're looking to make steel stronger, I can suggest 2 things: 1. If you're actually smithing the steel yourself, and forging it from hot liquid metal, then if you can get ahold of some Carbon (i have no idea where you can get some), you can add it to the molten steel to make it stronger. Sword Smiths did it all the time back in the Dark Ages. (you'll have to look up the exact Science and Process of how to do it) 2. There's a treatment for steel called Tempering. If you Temper the steel, it makes it stronger. You do this by 1st Forging what you're making. In this case, I'll use a sword. Take the Sword and re-heat it (i dont know the exact temperature) until it glows-hot. You can use a blast furnace, a campfire, or any other extreme-source of heat. Some companies use molten Salt - yes, the Condement, and dip the sword in it until it's glowing-hot. Now you have to super-cool it. This is simple, all you need is Ice water. Submerge the Sword in it, until it's cool to the touch. Now toss the Sword back into your source of extreme Heat. Get it glowing hot, and then take the sowrd out. Set it aside, and let it cool naturally. Once it's cooled, it's TEMPERED, and alot stronger. NOTE: If you stop at the ICE-WATER stage, you'll only succeed in making your Sword BRITTLE. You MUST Continue the Process once Started. - Hope this helps.
Q:Does mild steel rust?
Mild steel is an alloy. It is the most common form of steel. Mild steel (a so-called carbon steel) is a general term for a range of low carbon (a maximum of about 0.3%) steels that have good strength and can be bent, worked or can be welded into an endless variety of shapes for uses from vehicles (like cars and ships) to building materials. The carbon does not stop the material rusting or corroding. In addition to iron, carbon, and chromium, modern stainless steel may also contain other elements, such as nickel, niobium, molybdenum, and titanium. Nickel, molybdenum, niobium, and chromium enhance the corrosion resistance of stainless steel. It is the addition of a minimum of 12% chromium to the steel that makes it resist rust, or stain 'less' than other types of steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide, called the passive film. The sizes of chromium atoms and their oxides are similar, so they pack neatly together on the surface of the metal, forming a stable layer only a few atoms thick. If the metal is cut or scratched and the passive film is disrupted, more oxide will quickly form and recover the exposed surface, protecting it from oxidative corrosion.
