Q:Why is steel denser than wood?
Steel is basically a mixture (not the compound) of iron and carbon. Iron, by itself is an element and so is carbon. The atoms of Iron are larger in size compared to carbon. All the atoms of all the elements, smaller or larger, are spherical. If naturally a solid, the atoms of all such elements have voids as their atoms are closely packed. You can imagine a basket of oranges; you could see that void or empty space (which I am speaking about) between four or more of the oranges put together. Now, when heated to more than about 1500 degrees celcius, Iron melts and atoms in molten form increase space between themselves. Raising the teperature to 1800 degree celcius, carbon is mixed with iron. At this stage it causes the spherical carbon atoms to fill in the spaces present amongst the spherical atoms of the iron. On cooling, already dense iron becomes denser because no space is left there between its atoms. This denser form of iron + carbon has become steel in which carbon is not more than 3 to 4% of the total volume. Wood is nothing but a fallen and dried tree's part. When green and alive, tree's stem and branches have pores in there texture, which are fillled with water and other biological fluids necessary for the life of the plant. When dried all the fluids, especially water gets evaporated. and the pore are empty now. The term Density, means mass divided by volume (kg / cubic meters). Iron + Carbon (the steel) so tightly packed and Iron having very high atomic weight is surely denser than wood with just carbon and a few other elements with no significant role to play in the mass calculation; particularly if their are empty pore spaces filled with air only. Imagine the mass (which common people mistakingly call the weight) in kilograms of a peice of steel with dimensions of 1 meter cube and imagine the same for the dried wood. What do you think---which one is denser?
Q:is 440 stainless steel good for throwing knives?
Good steel ain't cheap, cheap steel ain't good... If you're just starting out (practicing anyways), I would be less concerned about the material and more concerned about the style and shape of the blade to gain consistency in your technique... When you start getting proficient for competitions and such... then I'd start investigating steel grades... Anyways, here's a summary from the wiki: Type 440—a higher grade of cutlery steel, with more carbon, allowing for much better edge retention when properly heat-treated. It can be hardened to approximately Rockwell 58 hardness, making it one of the hardest stainless steels. Due to its toughness and relatively low cost, most display-only and replica swords or knives are made of 440 stainless. Available in four grades: 440A, 440B, 440C, and the uncommon 440F (free machinable). 440A, having the least amount of carbon in it, is the most stain-resistant; 440C, having the most, is the strongest and is usually considered more desirable in knifemaking than 440A, except for diving or other salt-water applications.
Q:WHAT ARE THE WAYS THAT YO COULD PREVENT STEEL FROM RUSTING WHEN IT IS EXPOSED TO WATER? SALT WATER? VINEGAR?
rust is oxidation . remove contact with O2 , it wont rust . you can place it in a oxygen free atmosphere , you could plate it with zinc or chrome , you can use a lead based paint .

Q:How durable is stainless steel jewelry?
The bigger question is how will the watch movement hold up over time? If you have a lifetime warranty, don't worry about it they will probably offer a replacement if it gets too expensive to repair. Most men I know have given up watches except for the wrist jewelry look when going out, as you say. Because everyone carries a cellphone and doesn't actually need a wacth any more.
Q:HELP ME! Steel beam installation?
I see steel beams inserted into pockets in concrete foundations, they typically go 6 inches into the pocket. There is other problems with what you want to do. You must support the rafters while the work is being done. You must be sure your beam pockets are strong enough for the weight. another problem is that a steel beam this size is very heavy, How will you place it without a crane? Maybe an army of helpers can lift it. You may want to consider a laminated wood beam, they are lighter than steel.
Q:Is Steel crystalline in its makeup?
Steel Crystalline Structure
Q:Coating on Steel Wool?
It will be very effective if you remove the oil by appling protective polymer spin coating to the edge, top and underside of the wafer, which makes those surfaces impervious to most chemical etchants. To learn more about the spin coating theory you may check out the following source.
Q:When was steel first used in buildings?
steel was first used in the 1800s in buildings.
Q:Is sterling silver safer than surgical steel?
Surgical steel.
