Q:Are steel casings reloadable?
Steel Casings
Q:What material is strongest? Human bone, steel, or concrete?
Takfam is correct, but in the loooong run, concrete will exist for thousands of years after the steel oxidized, deteriorates, and disappears. The ancients compounded concrete even before the Romans (I can't recall but during the time of the Assyrians), and concrete is almost forever.
Q:Brass or steel cases through an AR-15?
my uncle is a cop and he received't run metal case by skill of his ar. it actualy did reason it to jam, and he cleans it after each decision visit. the element with ars is they are very low tollerance and require softer metals which will push them round esier. by skill of the years, metal will also positioned on down your internals swifter than brass because brass is softer. some mags each once in a lengthy time period wont damage some thing, yet when i wouldnt completely use metal case in mine.
Q:Steel content of kitchen knife any good?
I am a former chef and have used Chinese chefs knives, different types from cleavers, even french knives, they are mostly carbon steel, and are made with a cold forged process, they are as good as the European knives and are marketability cheaper, I have one a french knife a 8 one with a green non porous handle. I like it, it is light weight and very well made, and keeps an edge quite well, just look for the better type available.
Q:Purchase Steel - For Construction Purpose?
I'd keep in mind whether your potential supplier is close enough to still give you good service, and provide delivery when you need it. I'd want to contact as many local companies as possible, in order to get competitive bids. Then, I'd pick the lowest cost bids that I felt would still provide the service I needed. Most decisions of this sort, in the end, are based on price.
Q:Bike Frame-Aluminum vs Steel?
Dustin You are close, but not quite right. Steel is a great frame material, It can be heavier than its aluminum counter part, But, steel often provides a much nicer ride. Aluminum tends to be a very stiff and rigid ride that many do not like. I have had frames made of all materials. I can say that I have never met a frame material that I did not like. Check the weight of the frames you are looking at. If there is more than two pound (or so) difference then the aluminum frame would be my choice. Soccerref
Q:in what stores do they sell steel toe shoes?
Walmart Steel Toe Shoes
Q:Can steel dive deeper into sun?
Dont understand are you going to put them in sun ? Sun made from gas wich is on fire. Its impossible to get to the sun and not to get burn. Steel is really more solid and strong than iron so its more hard to break it or to bend. But in camparing of fusion temperature - iron is a bit more better, though it would not make a big difference .From metals - tungsten has the highest fusion temperature - near to 3400 C . Iron is near to 1530 C, steel is near to 1300 -1500 C. So according to this tungsten can go most close to sun. Right near the sun temperature is millions of degrees so anything will fuse and burn there.
Q:Stainless steel can be used to do??
Stainless steel can be used to (1) industrial use stainless steel (2) building decoration use stainless steel;(3) medical equipment (4) life with stainless steel tableware and the Jawaysteel is a great Chinese company, offer various kinds of stainless steel Maybe you can to their advice
Q:Can a 1000lb hollow steel ball float in water?
Say The radius of steel ball is R. Its shell is t thick so the air filled cavity if of radius r where r = R - t Steel has a density p The mass of the ball m is given m = 4/3 pi (R^3 - r^3) p If the ball is just to float then the mass dived by the must equal the density fo water d d = m / 43/ pi R^3 Equating m in the above equations yields (r/R)^3 = (p - d)/p or r = c R where c =((p-d)/p))^1/3 Using above leads to m = 4/3 pi R^3 (1 - c^3) p and hence R can be solved for So taking p (density of steel) 490 lb/ft^3 and d (density of water) at 62 lb/ft^3 yields c= 0.9557 Applying the equation above gives R = 1.565 ft or a diameter of 37.55 in The shell thickness is R (1 - c) or 0.06938 ft or 0.8327 in Note I do all my work in metric units so I had to do some conversions on the run. I hope you will check things to make sure the maths is correct. Anyway good luck
