Q:Why low carbon steel have poor magnetic properties?
The composition you mention is not a low carbon steel.The carbon and manganese content are high enough to mean that the crystal grain size will be small. A very large grain size is needed in steels for transformers,motors etc.The large grain size and lack of carbides in low silicon steels for magnetic purposes allows the easy movement of magnetic domain walls.Transformer steels typically have a carbon content of about 0.003% and 3.5%Si with the phosphorus and sulphur at a tenth of the levels you mention.The high Si content increases the electrical resistivity of the magnetic core and reduces the power loss from eddy currents(the core metal has voltages generated in it by the changing magnetic fields) and the power lost in eddy currents heats up a transformers core so it needs extra cooling;the loss is inversely proportional to the resistivity and 3.5%Si increases resistivity of iron by a very large amount.The presence of high silicon with ultra low carbon and manganese level allows the soft magnetic steels to be annealed at very high temperatures(850 to 1100deg C)without a phase change so that the crystals have 10,000 to 10,000,000 times the volume of the crystals in heat-treatable (Just)steel you mention.Fine for playing with and demonstrating electromagnetism but not as electrical engineering feedstuff.
Q:Can steel oxidize?????????
Yes - Steel can oxidize, its most commonly called rust Steel is a metal. Depending on the level of oxidation, you might be able to polish it with very fine steel wool. If is is really bad, then you might need a chemical cleaner such as Naval Jelly, which can be found at the hardware store. But the Naval Jelly might discolor the metal, so then you might need to polish it afterward to return its finish.
Q:Is this guitar steel string or nylon?
That's a very low-end Kay, maybe from the 60's or 70's. It has a weird mixture of steel-string and classical features that you often see in cheap imports from around that time, maybe because the factory didn't want to stock different parts for different lines. The tuners (one of which is missing) are made for steel strings. They will work with nylon but not well. The bridge is a generally classical type but appears to be bolted on and seems to have some compensation carved into the saddle, which indicates it may have been intended for steel strings. Probably it's ladder braced, which is not a great design for either type. It has a classical rosette and a steel-string pickguard. I am guessing the neck has steel reinforcement but unless there's a sticker there's no way to tell. Personally I'd put light or (preferably) extra-light steel strings on it. The short scale length will help keep the tension down. I'd keep an eye on the neck though. You could also try silk steel to be on the safe side, but the bass response will probably be lacking.
Q:Does a Butcher's steel actually make your knives any sharper ?
It does work but unless your technique is right you can knacker your knives. I think it is around a 45degree angle. You also need a good quality, rough, steel, if it's smooth and cheap it won't work. Having said that I knew an old farmer who earned pocket money out of sharpening people's knives and scissors with a stone and he got immaculate results.
Q:Steel horse shoes vs. aluminum?
Steel is not much different to be honest as long as you aren't doing any special shoes. A horse like yours I would probably stick in some steel eventers and go on your way. That's about average and honestly between a comparable aluminum shoe you won't see a difference in his movement unless the farrier starts messing with breakovers and shoeing him different. There are few times when I will do aluminum and all of it has to do with special circumstances. My 4 year old is in aluminums on his front right now because his special shoes are close to an 3/4 thick and about an inch wide. In steel those shoes would be very heavy, but those are what he works best in compared to the steel. I can give him more of the support he needs with the aluminum than I can with the steel. I also prefer eggbars, hartbars, etc to be done in aluminum for the sheer size of the shoe. Steel lasts more resets and it's stronger than aluminum. Aluminum is useful for therapuedic shoes. So you all have the pros and cons, but a horse in shoes with no special needs is a horse who should just stay in steel.
Q:Quick ... Does fire burn steel?
no, fire MIGHT cause steel to oxidize, depending on the alloy, but think of steel as a block of ice. Steel melts at 2800 degrees F and boils and evaporates at 5400 degrees. Some metals like magnesium can possibly catch fire but not steel
Q:Steel Clutch Vs. Transmission?
First of all it's not really a steel clutch..it is called a sintered iron clutch disk... a sintered iron clutch has a very aggressive amount of friction and is generally only used in racing application because of this...also it is ushually a non sprung disk. all of these factors = a very abrupt ingagement of the clutch which will shock the driveline very badly...say he's making 400hp and has really sticky tires..there is bound to be a weak link between the engine and the tires, in a factory driveline this would probably have been the clutch(it would slip) but since he has upgraded it he has now found the next weekest llink..in this case the transmission, he either needs to look into a beefier box or not launch the car so hard.
Q:Can you use steel strings on a classical guitar?
Everyone okorder.com/... The treble strings are steel, but are gauged so that they are at a lower tension than the treble strings on a western acoustic. The bass strings in Martin Silk Steel have a silk based core, and a metal wrap wire (just like in normal classical guitar strings), which again keeps the tension in the strings lower than its steel based cousins. The Martin Silk and Steel will give you a more western acoustic sound, but it won't be exactly the same as a western acoustic guitar.
Q:1 inch thick steel target good for mosin?
It sure will. It will also be a major pain in the back side to move it to where you can safely shoot at it.
