- 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:What and how hard is boron steel?
- Boron steel is rather hard, it is by no means titanium, but certainly better than mild steel. However, as with all metals, hardness is inversely proportional to flexibility, meaning that a good solid whack with a sledge hammer could crack your lock.
- Q:why use brass sell casings? why not steel?
- Expansion and more resistant to rust. Besides, steel cased ammo is made in East Eur..abia in all kinds of calibers but many people complain about it not being able to expand or that the steel wears out the extractor faster (not true), then they go and buy some.
- Q:building a lap steel guitar?
- Steel guitars have cables attached to foot pedals to change the sound. I don't know how this would work with the top resting on your lap.
- Q:is steel flexible?
- Yes, steel is flexible. Springs, like the ones holding up your car, are made out of steel. One reason why steel skyscrapers do so well in earthquakes is because steel is flexible. Piano wires are made out of steel. High tension wires for electric power transmission are made out of steel. Even a solid block of hard steel can actually bend and spring back, although it's very hard to see this tiny flexure.
- Q:Permanently expanding steel?
- You can calculate the maximum reversible strain, for elastic loading as follows: You need to look up the yield strength (for that particular type of steel). Divide this yield strength by the elastic modulus of steel (also called Young's modulus). That gives you the strain at the onset of yielding, the maximum you can strain the steel fibers before crossing the point of no return. If you are interested in the strain until failure, you need to take tensile test measurements. Seldom do people document an equation to model the non-elastic portion of the stress-strain curve of the specimen, because seldom do we design systems to operate with materials which yield. We want systems which only deform reversibly and elastically. This means you need to perform an experiment to find what you are actually desiring to know.
- Q:What were some steel advances in industries? 10 points!?
- The single most important important advance in steel production was learning to accurately control carbon content. This was done through the Bessemer Process in which air was blown through molten iron to burn out impurities and excess carbon. Low carbon iron (wrought iron) could be easily worked into shapes. Medium carbon iron could be cast into useful and durable shapes. High carbon steel could be used for structural uses (beams and girders). Adding alloys such as nickel and silicon could produce very tough steels and steels resistant to rust. Adding vanadium to steel engine parts allowed Ford to produce finely machined engines in huge numbers with existing machinery.
- Q:what caused my stainless steel sink to get rust spots?
- Use a soft cloth or nylon sponge and a little bit of detergent on the spot. Do not use bleach, chlorine or otherwise. If this does not work, try a little baking soda. Always rince out the sink after you use it, soap film can leave a rainbow looking mark in the stainless steel. I take everything out of the sink after I wash dishes. I use a small amount of veg oil on a paper towel to shine up the sink.
- Q:Galvanized Steel Poisoning?
- i have a dog with a galvanized chain on her neck ''for looks'' can she get even the slightest harmful effect from it being on her 24/7?
- Q:Is Carbon Steel a Metallic Material?
- Steel with a lower to medium level of carbon will typically be reserved for metal sheeting for use in construction, due to its increased hardness and malleability.
