Q:how is stainless steel produced?
There are different recipes, and different types of steel are made for different purposes. They all share high temperatures, which allows extra carbon to bind with the iron. This is the main thing that makes steel stainless, or rustproof. Other metals such as chromium, molybdenum, magnesium etc. are often added to increase tensile (twisting) strength, flexibility, etc.
Q:Is Galvanized Steel a raw material?
For paperclips, the raw material is steel wire. The company that makes paperclips does not smelt iron, they buy the steel wire at the diameter they want it and they feed it into automated machines that bend the wire and cut it to length. If you want to go back into the whole supply chain, then you are looking at a mine that digs iron ore from the ground. The iron ore (Taconite is one of the minerals but there are others) is sent to a smelter that combines the ore with coke (roasted coal) and oxygen in a huge furnace. They may probably add steel scrap, and continuously cast it into bar. good luck
Q:Steel sheet vs paper?
In okorder.com/... 11.7x8.3 inch paper 97.11 square inches 0.062651488 sq meters at 4.5gm is a non-standard 19 pound bond ledger paper, but that is OK, because at least it is in range. 38 gauge steel sheets are about the thinnest that hold their structure 0.00625 thick 1221 g/m² or, at 11.7x8.3 76.5grams So, with this data at hand we can better visualize the situation. Paper of 0.00625 thick in the size shown is 35# paper 131.68 g/m² 8.25grams Steel is higher in density than paper, so you cannot get the same size and air flow without it being lighter in weight than the steel and the air resistance would be lower for the heavier item, so steel of the same shape and thickness as paper falls faster. Suppose you want paper heavier than steel for the same area, then the thickness increases. Will a steel sheet 0.00625 thick and 11.7x8.3 inch size 76.5gm fall faster or slower than a 9 or 10 times thicker paper sheet? If it was able to hold flat in each type the thicker paper should get more backflow behind it aerodynamically and fall faster than an equal weight thinner steel sheet as my guess, but I don't have those numbers. The steel will always be heavier than the paper for the same exact shape and thickness by about 9x. My answer here is difficult, but the question has some flaws to think about.
Q:how strong is 440 stainless steel?
For throwing knives, 440 isn’t necessarily a bad choice. Does it list whether it is 440c or 440b? That matters somewhat. The advantages of 440 Stainless is that it’s relatively hard (for a stainless), it resists rust significantly, and it’s not so hard that it would shatter or break. On the down side 440 is notorious for not taking or holding an edge, but for a throwing knife, that’s probably not much of an issue. If you’re looking for something to train with, you’re fine here. It’s plenty of steel enough to stick in wood or other targets. Odds are it won't bend if you slam it into some wood. If it lands on concrete, eh, it's going to scratch and all that jazz, and it might hurt the tip if it hits first, but as has been said, you can use a file or grinder to get the tip back.
Q:Where can you get a thick sheet of steel?
Try the business-to-business yellow pages in your area. A local hardware store can also tell you who to contact. Or search steel plate or sheet metal on the internet to find a local supplier. No, sheet steel is not bullet proof, unless you get heavy plate. Depending on how thick it is, the plate will deform if hit by a high velocity bullet, but usually not enough to matter. Bullets have velocities from about 500 ft/sec up to roughly 3000 ft/sec, depending on the type of weapon used. I wouldn't try to use anything thinner than 3/4 inch. You'll have to experiment and see what it will actually stop. I can't guarantee it'll stop a high-velocity rifle slug. Try it and see.
Q:What makes Steel stronger than Iron?
Cast Iron' is typically brittle, while 'Maleable Iron' has a small percentage of carbon which allows it to be hammered and formed. Steel is an alloy that consists mostly of iron and has a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron. Steel is a crystalline structure of iron molecules interspersed with carbon molecules. This is properly known as cementite. The hardness and malleability of steel depends not only on the carbon content, but on how the carbon and iron molecules are arranged to one another. Internal stresses in the steel's crystalline structure will increase or decrease depending on the temperature it is subjected to and the rate at which molten steel is cooled. This 'tempering' can increase the strength of the steel at the expense of brittleness.
Q:Damascus Steel vs. Carbon steel with a simulated temper for a sword?
Damascus steel is in history books only,no body knows its composition.THey just named a modern steel as Damascus steel
Q:how to understand the chemistry of a metal.. especially steel.. from their names...?
For steels with a four number code like 1020, 4140 ect the first two digits are the alloying information. I think you need to memorise those. 10 steels are plain carbon steel with no alloying. 41 steels are chrome-molly. The third and forth digits are the carbon content. 1020 is 0.2% Carbon, 4140 is 0.4% carbon. I don't know if there is a system to stainless steels.
Q:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
In order to prevent rusting in the process of storage or transportation of steel roll, steel mills generally take the following packing: inner gas antirust paper wrapped with tape wrapped in plastic film sealing, intermediate, involute cardboard seal lining, cardboard corner, with iron and steel outer package corner protector, strapping fixed. If the inner package seal, so the steel coil is sank into the water, will not rust out.
Q:Science Question About Steel?
Carbon 'tempers' steel, by making it harder and less prone to bending (ductility). It fits the carbon atoms into the spaces in between the crystal lattice structure of the iron atoms. Too much carbon means the steel becomes more brittle, harder to weld and thus more likely to shatter under stresses which are perpendicular (shear forces) to the crystal structure of the molecules. It also is very difficult to work, requiring very high temperatures.
