Q:Which is stronger, Wood or Steel?
steel bridges that have been made of wood lasted way longer than steel bridges NOT true. Why do you think bridges are made from steel or concrete, and not wood? wood rots and splinters and doesn't last more than 10 years when exposed to the weather. .
Q:Stainless steel or white appliances?
We got rid of the Stainless Steel because they showed every smudge, finger print and smear. Very hard to clean. Harder to keep clean. I recommend any color except Stainless Steel.
Q:Steel Buildings!!!!!?
Yes of course they look nice and I think they are more durable and weather resistant than conventional concrete buildings. So if you are thinking of constructing a building then opt for steel buildings buddy :)
Q:Will carbon steel knives stick to a magnetic knife strip?
Carbon steel knives will stick to a magnet. Stainless steel may not.
Q:What does Blue Steel meen?
Reference is to a gun which is typically the process of Bluing the steel of the guns metal parts.
Q:Quality of Cold Steel Recon 1 (folding knife)?
I recently bought the same weapon and am really impressed. There is no decline in quality and it arrived sharp enough to shave with. I rank upon the finer knives that I own. I would not hesitate to use it in a defensive situation (or offensive).
Q:has anyone heard about the 2010 specialized allez steel?
Steel? I doubt it's made out of steel, more labor and a heavier frame. Most likely aluminum. Shimano 2300 you say? The Shimano 2300 is the lowest of the low of Shimano road components. Most likely not too reliable and heavy. www.cyclestore.co.uk/productDetai... I think this is what you might be looking for.
Q: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.
Q:How much pressure can concrete and steel take?
A common allowable stress for steel is 24,000 psi for A36 steel. Note that allowable stress is a working stress that is less than ultimate stress the stress at which the material will rupture. This allowable stress keeps the steel within the elastic range. Concrete allowable stress is typically around 3000 psi. Concrete, though, being a mixed material has variable values for allowable stress. Reinforced concrete design theory suggests that concrete should not be considered to be able to carry much, if any, tensile force. This explains why you will see steel rebar or reinforcing bars cast in to the concrete. The steel is there to carry any tensile forces, while the concrete is there to carry compression forces. This is a VERY basic explanation. There are entire books on both of these subjects...
Q:How to temper steel? ?
Heat treating easy, HA! It is the most critical part of bladesmithing. Done wrong and all those hours of work go up in smoke (or a snap of the steel). You'll need a bucket of oil, preferably one that is deep enough to go in point first. If not you'll have to go in edge first, not recommended on a double edged blade, ok for single edge. You'll need to build a charcoal fire long enough for the blade. You will need to blow air under the fire to get it hot enough, the challenge is getting the heat even. You get the fire going and established, put the blade in turning it back and forth (if you keep turning it in the same direction when it heats up you could work a twist in it). When it starts turning red pull it out and touch it with a magnet, if the magnet sticks put it back. Keep heating and repeating until the magnet no longer sticks. Heat a little more, then quench rapidly point first. Don't let the blade lean to one side as warpage will occur. When it cools enough to touch, check with a file. If the doesn't file cut then you've properly hardened the steel and it's ready for temper. Now comes the really hard part. Grind the scale off carefully,preferably with a side grinder with a flap wheel. I've had hard wheel break freshly hardened blades. After cleaning you'll need to put it in an oven (preferred) or use a torch and carefully heat the blade. Watch the temper colors (oven temp 500-550F) or with the torch as the steel turns colors blue to purple for a double edged weapon. Any warpage that occurs needs to be worked out at temping temp.
