Q:What kind of steel alloy have the strongest attraction for magnets?
Magnet
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: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:Will painted steel rust?
Rust is the process of steel oxidizing when in contact with oxygen, this reaction can be much fast if certain components are present, such as wet air or water. However, if the paint completely isolates the steel from the environment, the encompassed steel will never rust as long as paint shields it. Aluminum corrodes but it does not rust. Rust refers only to iron and steel corrosion. Aluminum is actually very prone to corrosion. However, aluminum corrosion is aluminum oxide, a very hard material that actually protects the aluminum from further corrosion. Aluminum oxide corrosion also looks a lot more like aluminum, so it isn't as easy to notice as rusted iron.
Q:what type of steel is used to make rail tracks?
Well i guess they have to ( engineers ) take into account stuff like tensile stress and crap and then also the amount by which it contracts and expands during extremme tempertures if i were you put this question under the engineering section. It might lead to a right on the nail answer and also there ought to be a log book which gives us like you know the best steel for railroad maufacture. Architectural engineers or construction engineers are always goin around with books bookworms to be more precise. haha anyways best of luck mate.
Q:how to tell if its really stainless steel?
Magnets stick to some stainless but not all of it, so a magnet is not a reliable indicator.
Q:How do you melt steel without a blast furnace?
Iron melts at a very high temperature, so if the goal is to melt it, then there will be a certain amount of intense heat of course. Steel is recycled in a carbon arc furnace. The bottom is lined in graphite. Large graphite rods are lowered into iron scrap and enormous amounts of electricity melt the iron due to the heating of the carbon due to its resistance. The carbon also removes any oxides by forming CO2. Aluminum and lead can also be recycled in this fashion. Ordinary rust can be turned into liquid iron through the use of the thermite reaction. Rust and aluminum power can be ignited with a propane toarch or a magnesium ribbon fuse. The aluminum is oxidized and the rust reduced to molten iron. This reaction is used to spot weld cracks in steel structures, like railroad tracks. It is also a popular arson device used by spies.
Q:Is Steel a Pure Substance or a Mixture?
Scott, there are 3 types of materials: elements, compounds, and mixtures. Compounds are covalently bonded elements. Compounds and elements are both considered 'pure' substances. Mixtures are not bonded in any fashion. So a steel mixture can have varying amounts of iron, carbon, silica,molybdenum, etc., giving the steel the desired properties (strength, rigidity, rust resistance, etc.).
Q:quinching steel... hardening?
boy what a though question ! let me explain. when you rapidly cool a steel from high temperatures(depending on steel type) with water or oil or other means , it is called quenching. it depends on the steel type to say if it is better to quench it with oil or water but basically in water you will have a harder steel rather than oil. for some steels if you do this you will ruin it's properties ! you can't totally tell what kind of steel do you have until you get it analyzed with Quantometer analyzer with a pocket knife it is more like an estimation and it can't be trust able generally if you can scratch the steel with your knife it means it is not a hard steel and it might not be expensive. I hope that helps but for more information i need to know more !
Q:Origin of the steel guitar in Country music?
As I don't know for sure I have a couple of really good guesses. I would say either Jerry Byrd of Ernest Tubb's Texas Troubadours or Don Helms of Hank Williams' Drifting Cowboys. I can tell you for sure that Bud Isaacs was the first player to use a pedal steel guitar on a hit recording: Slowly by Webb Pierce in 1953.
