Q:what is the origin of stainless steel?
Source Of Stainless Steel
Q:whats the benifits of using steel material for fasteners?
Relatively cheap, strong, and non-toxic. For Carbon Steel alloys rust and corrosion are problems. For stainless alloys, cost becomes the problem [and corrosion is not eliminated]
chromium nickle steel aka stainless steel exact amount of chrome and nickle will determine type/grade numbers Check the google for steel type/grade Never head of aircraft grade, however,, there is marine grade - normally baltic birch with waterproof glue and no defects i.e. knots, etc. Very strong (also quite expensive) but worth it for the correct applications
Q:Mag. Wheel (steel and aluminum info)?
Negative facts for steel wheels: (1) Not as many style choices as aluminum. (2) Rust easily even when painted or powder coated, due to rock chips. (3) Heaver than aluminum, as far as fuel economy. Negative facts for aluminum wheels: (1) More sensitive to proper torquing of lug nuts. IE torque must be checked more often. (2) Susceptible to impact damage from road hazards much more than steel. (3) Need constant attention to prevent oxidation. Are these what you are looking for? I hope so. Wingman
Q:Galvanised Steel Questions?
Dear HC, You have a great military box and a cool conversation piece. Take a vacuum and clean the dust. Take some 0000 steel wool and use on the steel parts. This will take some elbow grease! If this doesn't work try some 320 grit sand paper. lightly sand the wood and brush polyurethane on everything . The box doesn't pose any health problems. Also you might find that the box will bring a pretty good price if you decide to sell. Good luck. Sniper
Q:i want to see the atomic structure of carbon steel?
This is actually a quite complex question... The atomic arrangement in steels can be controlled over a pretty wide range of different structures. This is really the fundamental reason why steel is such a commonly used material. The different atomic structures produce different physical properties so metallurgists have developed many different processes to control the atomic structure to get the properties they want. One simple answer is that Fe is BCC, body centered cubic at room temperature at equilibrium conditions. When you heat Fe up, it transforms to FCC, face centered cubic. If you continue heating Fe, it goes back to BCC, then it melts. The addition of C makes these structures (and the transformation temperatures) different. Deviating from equilibrium conditions by, for example, cooling very quickly (quenching) creates different atomic structures (one of the most important is known as martensite). Depending on how much C is in the steel, you can also have two different atomic structures (two different phases) present in equilibirum, for example, pearlite which is a mix of alpha Fe (BCC) and iron carbide Fe3C (orthorombic crystal structure). So... you need to think a little more about exactly what you want a picture of. I hope this helps
Q:the difference between mild steel and steel?
As the first answers suggest, the prolbem is that these terms are not specific, they are not scientifically or technically defined. This is like asking: what is the difference between a four door car and a sedan? There are hundreds of steel alloys ranging from Fe + a little C + very little else to alloy and tool steels with significant amounts of Cr, Ni, Si, and a number of other elements + C. And... for any given steel alloy, there are many different ways to heat treat it. A given piece of steel can be heat treated so hard and brittle that it could shatter like glass and then it could be heat treated to make it into a spring or heat treated to make it stretch like taffy. If you really want to understand steels, yes, there are lots of books on sword making (some written by people who actually understand steels) but... you need to study metallurgy. There are graduate level courses just on the metallurgy of steels. Of course to understand this course you need to understand a whole lot of fundamental metallurgy. All this stuff on steel makes perfect sense because, in terms of weight (tonage) produced, steel is, hands down, nothing else remotely comes close, the most important metal humans have.
Q:POkemon best game steel?
Robopon ;) Transformers? really... fail joke, Robopon is essentially pokemon with robots ;) But on-topic, i believe Platinum would be your best choice.. from memory, it had no end of steel and steel-hybrids.
Q:Nylon Or Steel Guitar FAST ANSWER!!!?
He's using a nylon guitar. The trick to know whether it is nylon or steel is by looking at the headstock. steel ones use the ones you see from a regular electric guitar. the nylon ones has two major holes on them I don't know why but that's based on what i have seen. One more thing is its bridge. the nylon ones do not use pin-like stoppers to prevent the strings from falling off unlike the steel-stringed guitars that use them.
Q:Is it me or is everything steel in pro wrestling?
The guard rails have to be steel or fans would tear them apart. The steps have to be steel..( although they are not 'solid steel'), in order to hold all that weight of people going up and down them for an entire show. The chairs are very forgiving. All in all, I can see where you are going with this, however it has been this way for decades now. Notice there are no steel tables or steel announcers desks?
