1.Structure of Cold Rolled Steel Description

The raw material of cold rolled steel coil/sheet is high quality hot rolled product, and after pickling continuous rolling, degreasing, annealing,skin pass,slitting and cut to length line etc. Along with it many kinds of new  technology and new process of global cold rolling production have been applied. Therefore the quality of the goods could be guaranteed. The product is widely used in outdoor and interior decoration, furnishing manufacturing, home appliance, automobile etc.

Q:Best affordable steel combat knife?
Sorry, probably aint gonna happen in that $ range. How big of a blade will effect the steel selection. For instance I have one I forged from 52100, a most excellent steel better suited for 5-6 blades. For larger blades either 5160 or L-6 can make an indestructable blade. For 5 and under D-2 is about as fine a steel as you can get. No blade made from these will come cheap, L-6 is only available from custom makers. Save up your money, expect to pay 100 - 200 for a well made blade. You pay cheap prices you get cheap workmanship.
Q:Titanium or Tool Steel?
Titanium is a significantly stronger and lighter metal, but is also extremely expensive. If you have the option for titanium, go for it.
Q:911 conspiacy theorists. Can fire melt steel?
Don't know the differences in steel strength between the WTC towers and the bridge, but I'll tell you they don't always use the strongest steel in buildings. It is a question of value engineering. Engineers do as code requires, and make the determination based on economics of building. If a steel member requires say 48 KSI, with certain span, but if the price is less expensive to use 35 KSI and reduce the span by adding vertical elements then that is an option that the architects, engineers and developers consider. Like I said, don't much about bridge engineering, but in buildings, it isn't always the strongest steel, based on engineering and economics. And BTW, said time and time again, but ok one more time. STEEL DOESN'T NOT HAVE TO MELT FOR FAILURE. IT LOSES STRENGTH WITH HEAT. THAT IS WHY IT MUST BE PROTECTED BY FIRE RETARDANT. BUT IF THE FIRE RETARDANT IS REMOVED BY EXPLOSION, THEN FIRE CAN CAUSE FAILURE. Sorry for the shouting, but I'm not the only one who says that, but people keep saying steel can't melt, but it doesn't have to for failure. If the steel joist had been in concrete, the WTC towers may have stood, at least longer. But hindsight is 20/20.
Q:dangers of the steel factories?
Same as other steel plants, getting crushed by falling steel, getting burned by hot metal etc
Q:Is blue steel stronger than stainless steel? i heard it is.?
Stainless steel requires less maintenance, but I've got a K-38 Combat Masterpiece from 1974. Back then SW used the real blueing process, and the blue steel looks like its a foot deep. Probably the best looking gun in the accumulation. Still new in the box, never fired. Its my Vietnam tribute gun, same one I carried as a Security Policeman in the Air Force from 1969-1971.
Q:Angular Velocity of a Steel Ball after a Collision?
You need to do conservation of angular momentum about the steel ball's axis. Angular momentum = I.ω The steel ball's initial ω = 5 rev/s = 5*2pi rad/s = 31.4 rad/s The steel ball's moment of inertia I = (2/5)*m*r^2 = 40*25 kg.m^2 = 1000 kg.m^2 The marble's initial ω = v / r where r is the perpendicular distance from the steel ball's axis You need to look at the diagram for this. The marble's I about the steel ball's axis is I = m*r^2 where r is the same as above. (marble is treated as a point mass). Then work out the total initial ang. momentum = final ang. momentum and solve for ω...
Q:what types of stress require steel to be placed in footings?
Shear and bending stress.
Q:Which one is better to start? Steel or Acrylic tapers?
Steel
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:what is the stucture of high carbon steel?
I dont know percentages just that it is basic steel with added carbon it is used for tooling and other reasons that need a steel that can be hardened ~~
