- Q: im buying a new guitar,, it has a built in tuner and its semi acoustic (can be plugged into an amplifier) ,, im trying to choose which strings are better ,, steel or nylon..?
- That's not an option Guitars are designed for either nylon or steel strings. They aren't interchangeable. Putting steel strings on a guitar designed for nylon strings WILL destroy the guitar. If you've already picked out the guitar you want, then you've already made your decision about nylon or steel.
- Q: Can solution annealing be done on carbon and low alloy steels. please give an explanatory answer.
- No. Carbon steel has two different crystal structures, FCC and BCC , depending on the temperature. when you heat steel up and then quench it, it locks the crystal structure into the BCC form. this makes it hard. whereas precipitation hardened austentic stainlesses remain BCC regardless of the temp, so the hardness change is not a function of thermally induced strain. you can anneal carbon steel but the thermal profile is closer to the precipitation profile of PH stainlesses than it is to the Solution annealing profile.

- Q: I need to construct a table with three columns, which states the name of the steel, its compositions (e.g. Fe and C), and its special properties for a variety of different steel products.Help me please, a site with info would be great, explanations would be even better.
- Steel is an alloy consisting mostly of iron, with a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron, but various other alloying elements are used, such as manganese, chromium, vanadium, and tungsten.[1] Carbon and other elements act as a hardening agent, preventing dislocations in the iron atom crystal lattice from sliding past one another. Varying the amount of alloying elements and form of their presence in the steel (solute elements, precipitated phase) controls qualities such as the hardness, ductility, and tensile strength of the resulting steel. Steel with increased carbon content can be made harder and stronger than iron, but is also less ductile. H.
