Steel Pick + Acoustic Guitar = Trashed Guitar?
- That's not a question, it's a statement. And how would using any kind of pick trash a guitar? At worst it would harm a $5 set of strings, not the guitar.s

Is mild steel environmentally friendly?
- Steel just rusts, it doesn't produce any emissions just sitting there. They even make architectural steel called Corten to rust to a nice patina. If you consider how the steel was made in the first place, a great big NO! Steel making requires massive amounts of electricity plus it gives off some nasty fumes in the liquid state. Leather itself doesn't emit much of anything, but the dyes might. Again though, if you look at how it's made, tanning leather is right up there with steel mills and paper mills for pollution, some of the worst.s

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.s
what is 440c stainless steel means?
- It is the alloy number given by the American Iron and Steel Institute, or AISI. This is the trade organization of the U.S. steel industry, one of the oldest such organizations. 440C is also known under the UNS system as S44004 440C is a high carbon, plain chromium stainless steel. Or more specifically: 18% Cr, ~1.1% C, ~1.0% Mo, Si, and Mn 440c is mostly used in cutlery, bearings, and valve parts; because it has the best strength and hardness after basic heat treatment of any stainless steel. Relatively poor properties in other areas make it less suitable for other types of items. for example 440c becomes very brittle in sub zero temperatures. 410 is similar to 440, but it is a cheaper milder steel with less chromium and carbon, so it is less brittle, more easily worked and machined, but lacks final strength and hardness. it is often used in cheap stainless fasteners and bushings.s
