Q:What steel is the most magnetic?
Silicon steel is the most magnetic material for making into transformer cores and motor cores. It contains 1.25 to 2.5% Silicon. Silicon steel is usually rolled to 2mm plates as lamination material. Iron may be magnewtic but it has low resistivity. With high silicon alloyed to iron resistivity is increased and core and hysteres are losses reduced. Important silicon steels are designated as AISI M15, M19,M22 and M36. In ASTM, these steels are designated 36F15, 36F18 and many more.
Q:Which one steel or metal?
hi Asking this question in engineering category would give you the following answer steel is a subcategory of metals moreover steel is iron with some other additions( mainly carbon) strong in the engineering sense is not a specific word..i mean we , in engineering, have many scales to categorize metals ( which include steel)..like hardness,corrosion,elasticity, and even heat conductivity...every metal could be strong in some and weak in other but i can understand that you are not an engineering type :) that's why here's a special answer for you steel usually has the silver shiny color ( i am not sure all grades of steel have this color)...it would be more EPIC to use steel bow and arrows... if it's a fictitious books...you can just use Iron or any name you can made up... You can search....how did the ancients make their bows and arrows? thanks :)
Q:Explain how you could make plastic sink and steel float?
plastic can be denser than water. Make it a brick and it sinks. Ships float because they are mostly air - surrounded by steel.
Q:Stretching Ears: Acrylic vs Steel?
Steel is much better because acrylic can't be sterilized. If you have the option, titanium is much better because steel can cause nickle allergies, which can get pretty irritating.
Q:where is cold formed steel framing used?
It will vary from location to location. A possible way of telling is how the material is joined. If the material is riveted together it is likely cold rolled. If the material is welded then its probably normalized steel (possibly annealed but less likely). Cold rolling increases the yield strength of the material so less of it is needed. However, it also make the material more brittle. Welding creates defects in the region surrounding the weld and these are more likely to grow and cause failure in a cold rolled steel than a normalised or annealed steels. In addition the heat from the welding will change the microstructure that was deliberately introduced by the cold rolling process resulting in a localised drop in yield strength. Normalised and annealed steels are more ductile and tougher than Cold rolled steel but they have a lower yield strength. Because they are tough and ductile they are less sensitive to crakcs and defects so welding won't lead to as big a reduction in strength. Another possible consideration is the environment they are used in. Steels exhibit a transition temperature (actually more like a range) where they go from behaving like a ductile material to a brittle material. A well known example of what this can cause are the Liberty ships in WW2 (Supply vessels from the US to the UK). These were made by welding together sheets of cold rolled steel to form one continuous Hull. Unfortuantely the transiton temperature of the steel taht was sued was around 4 degrees while the Baltic Ocean is about 0 degrees. As a result small cracks would grow and then when the reached a critical size they would tear through the ship at the speed of sound in the metal (1500m/s) and these massive cargo ships would literally snap like twigs. So, if the steel is being used somewhere really cold its unlikely to be Cold rolled too.
Q:pedal steel guitar...?
I agree with everything that Lester said. Another thought is to consider starting on a lap steel guitar rather than a pedal steel - its related, a little easier to learn on, and less expensive. Once you get proficient on the lap steel, you can move up to the pedal steel. Good luck!
Q:Does steel have water in it?
Condensation forms when temperatures vary 'quickly'. The air itself is what provides the moisture. There you go.
Q:Where do I need hot galvanized steel coils and color coated rolls?
In industrial or coastal areas, due to the influence of sulphur dioxide or salt in the air, the corrosion rate is accelerated and the service life is affected. In the rainy season, the coating has been soaked by rain for a long time, or the temperature is too large and easy to dew. It will be corroded quickly and the service life will be reduced. A building or building made of colored coated steel plates, often with a long service life when washed by rainwater, otherwise affected by sulfur dioxide, gas, salt, and dust. Therefore, in the design, if the roof slope is greater, the more difficult to accumulate dust and other dirt, the longer the service life; for those areas or parts that are not often washed by rain water, should be regularly washed with water.
Q:what type of steel is used to make rail tracks?
I don't know what the technical name is, but steel used in rail is higher in carbon content. There is a trade-off as the higher carbon content tends to make them more brittle, and those rails with the highest carbon content are used exclusively for tight curvature in heavy grade. It's amazing to watch the welders with this stuff. Torches take too long, so diamond saws are utilized for cutting. The stuff is more problematic in severe cold, too. Railroading in the mountains as I've always done, nighttime and its severe chill causes pull - aparts, due to the contraction of CWR (Continuous Welded Rail) as a result of the cold, at least two or three times a week. In an extended deep freeze, the problems are nightly. What is interesting to note is that the pull aparts tend to happen with equal frequency regardless of whether a part of tangent track or curve. Still, I'd rather have it under me. I know it caused some major problems on the SP in the '80s, but it was cheaper, imported steel that was the significant part of the problem, not so much the high carbon content. Once again, you can't beat US steel.
Q:What's the length of a coil of cold rolled steel? Is there a standard?
And the length has a lot to do with the thickness. So the total length of the volume is not good.
