Q:Should I buy a guitar with nylon or steel?
Small guitars easier to find in classical range. I assume their must be small steel strings but not seen them.
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:Who or Where can I buy a Steel Pipe Making Machine?
I'll answer both those questions. Your first question is: Who can I buy a Steel Pipe Making Machine? To which I reply: anyone. I'd put great consideration on the age of the person you are giving this machine to, and perhaps their physical ability. Cripples don't work well with steel pipes. Unless you are...beating them with one. Second question is: Where can I buy a Steel Pipe Making Machine? My reply: OKorder, or Steel Pipe Makers Incorporated. You could probably just steal one out of their factories. They have billions, and the actual machines are no bigger than...a bus or two. Just pop one in your backpack on the way out. But honestly, I don't know where to get a steel pipe making machine. BUT! I do know where to get a steel pipe making machine making machine. Ask santa. (BTW: Why do you need the steel pipes? I smell conspiracy!)
Q:What is the difference between weldable steel and plate steel?
Weldable steel is a generic term for steel with low carbon content which makes it easy to weld, form, and machine. If you're looking for a knife blade material, you need either a stainless steel or a high carbon steel which is not at all weldable. The more carbon in steel, the better it responds to heat treatment like hardening, tempering, etc. Plus, the high carbon steel will hold an edge better. Hope this helped.
Q:Maple Story Steel Polearm?
you dont buy it, you earn it in the lottery cassandra was doing(it passed).
Q:quality of steel ..................!!?
Various ways: Carry out mechanical testing on it to see how strong it is. eg. Tensile testing, hardness testing, impact testing. Examine a cleaned up sample on the steel under a microscope to see what the steel grain structure is like and what condition it is in (hardened etc.) Or the easiest way is to ask the supplier what it is and then find a specification sheet giving you all the above information.
Q:.308 steel cased ammo in my remington 7400?
Kudos to NXile for his/her post. Ironically, I recently posted a similar answer in this forum and got many thumbs down. The problem with the non-expansion of steel cased ammo is not limited to the blow-back and soot build-up inside the action. The other problem is that your Remington 7400 was engineered at the Remington factory as a sporting firearm that uses brass cased sporting ammunition. When you switch to the steel cased ammo, the casing doesn't have a chance to grab at the walls of the chamber to slow it down. The result is heavier recoil on the action of the gun. Over time, you will break something. Also, I don't like the idea of steel rubbing against steel inside the chamber area of a gun. I know sure sure I won't use steel cleaning rods or brushes to clean the barrel of a rifle. So why would I want to chance shooting steel cased ammo? The only stuff I will shoot steel cased ammo out of are the junky SKS and AK style rifles that I don't care about. Anything with real value...and I only use brass ammo with non-corrosive priming.
Q:Bike Frame-Aluminum vs Steel?
Dustin You are close, but not quite right. Steel is a great frame material, It can be heavier than its aluminum counter part, But, steel often provides a much nicer ride. Aluminum tends to be a very stiff and rigid ride that many do not like. I have had frames made of all materials. I can say that I have never met a frame material that I did not like. Check the weight of the frames you are looking at. If there is more than two pound (or so) difference then the aluminum frame would be my choice. Soccerref

Q:DUCTILE-TO-BRITTLE TRANSITION TEMPERATURE IN STEEL LOW CARBON?
The temperature varies with the type of low carbon steel and how it is heat treated. Common structural steel actually have a transition temperature as defined by Charpy impact tests to be in the 50 degree range. Most low carbon steel pipe such as ASTM A53, A106 and pressure vessel plate such as A212, a515 also have 50 degree range Charpy test results. If you look at materials with fine grain such A516 plate, A300 pipe and similar materials then the transition temperature drops to around -50 degrees. The thing to remember is in addition to the transition temperature you also have to have the material at a high stress level, a stress riser such as a notch and then the sudden application of additional stress to get an actual brittle fracture failure. That is why bridges make from common structural steel don't fail at temperatures as low as -40 degrees.
