The plating coat of Aluminium-Zinc Alloy Armor plate is Zn-Al alloy, and its composition is 55% Al, 43.3% Zn and 1.6% Si. The plate is of smooth surface and excellent corrosion resistance of the atmosphere, which is 2 to 6 times higher than hot-dip galvanized sheet of the same thickness of plating coat. After through three processes, including payoff reel, crop shear and welding, enter into the continuous annealing furnace. During the annealing process, strips are heated closer to the recrystallizing temperature, and then heated to 20~50°C above the recrystallizing temperature in the reducing furnace. After keeping the same temperature for 170s, strips are naturally cooled to the normal temperature in the slow cooling process. Afterward, strips enter into the zinc pot through the elephant’s trunk and begin in the hot-dip coating process. The optimum temperature range of the plating coat is 630°C~660°C. Coated with aluminium-zinc alloy, strips enter into the cooling tower by the steady roll and air knife. After fast cooled with wind or water, they are directly produced into Al-Zn armor plates. The general rate of cooling is 30°C/s or so, and strips are cooled to about 60°C.

Q:Heat treatment of mild steel? Process description macro-micro
Mild steel is a solution of carbon within iron, etc. When the steel is very hot the carbon is well distributed. As the steel is cooled iron crystals form excluding the carbon that will then collect at the boundaries (grain boundaries) between iron crystals. If cooling is rapid at any point in the cool down crystal growth will cease (affecting final grain size and the mix of carbon and iron at the grain boundaries). The ductility or hardness of the resulting steel will be determined by the grain sizes and makeup of the carbon/iron mix between grains. Ductile iron permits 'slabs' of iron to slip past each other within iron crystals and location of carbon atoms may help prevent slip resulting in hardness. Therefore, heat treatment usually consists of 'soaking' the steel at a temperature high enough to dissolve all the carbon uniformly then cooling it down slowly or rapidly to obtain optimum grain size and interstitial carbon between grains to obtain desired properties.
Q:Carbon Steel/ Stainless Steel knives?
If your talking about a folding pocket knife, I think that it's basically six one way and a half dozen the other. I actually do prefer stainless for my pocket knives. I don't want to oil a knife to the degree I feel carbon requires, only to then stick it my pocket to attract dirt to the knife and oil to my pants. I'm the exact opposite on sheath knives though. I like 1095 carbon steel, plain edge sheath knives. I'll thrash on them HARD, and I rarely have major edge problems. Of course, I require them to be coated with some kind of powder coat or the like, because they can rust, but I do try and keep them clean and dry when in the sheath, so they won't pit the uncoated edge. My reasons for this sheath knife preference is multi-fold. First, these knives are simply affordable. I don't spend $80 dollars on a outdoors sheath knife. I use the tool too hard to want to spend more. I don't like the more traditional stainless steels such as AUS-8, 420HC, and 440C (not to mention the HORRENDOUS 440A) because I feel that the all else being equal, a stainless blade will bend before a carbon blade will break. I also think that carbon holds an edge at least as well, if not better, than traditional stainless, and it's much easier to hone. I don't know much about these new laminates, other than the very hard, but not so tough. They seem to be POSSIBLY too brittle for my use. That, combined with the fact that they cost a FORTUNE, means that I just won't be considering them.
Q:Anyone seen Man Of Steel?
saw it yesterday and it was great. all the complaints about it being gloomy...nonsense really. how would u feel if u found out ur life was a big question mark THEN u grow up only to get tossed in giant sh*t storm. many right now are excluding this is a story driven movie/character. u can't go in expecting anything with this movie especially ANY comparison to precious films. between Reeves and Cavill... I'm not gonna make that decision yet. this portrayal was one of a complete serious nature. u only get a couple glimpses of other emotions. the ending was a great lead off in which the sequel will showcase a lot more emotion within the character guaranteed. for now Reeves is still the best. until we all see Cavill display a full form of charm and charisma then the entire debate is really pointless
Q:How much is 18k steel and gold worth?
Steel does not come in an 18k version and is worth only about $1.50/pound. 18k gold (.750 or 75% pure) is currently worth about $40.20/gram, based on the spot price of gold of $1,667/ounce at this moment.
Q:Copper pots....tin or stainless steel lined?
Stainless is a fairly poor conductor but that is not why it has hot spots. That's because they tend to be thin. Cast Iron is also a poor conductor and has about the most even heat distribution. Many Copper bottom pots are just Copper plated for looks. In fact only the most expensive will have the heavy Copper bottom needed for even heat. Tin is a metal, an element. Stainless Steel is a mixture ( alloy ) of Iron and Chromium or Nickel or both. I do not know of any cookware that is Tin plated on the inside. I like Aluminium clad Stainless Steel. Good heavy bottom for even heat and Al. is a good conductor. A little more expensive are three layer bottoms. They have the Al. between Stainless so you get the looks and easy cleaning os SS with the heat distribution of Al.
Q:How is steel coloured?
Steel can be plated(Chrome),Blackened(Black Oxide),Powder coated(color of your choose).All of this is done to prevent rust.All of these aforementioned processes can be worn off through being used.I suggest polished Stainless steel.
Q:Is Grade A Surgical Steel...?
Perfect! 3
Q:Steel plugs in the winter?
I have never had a problem with mine in any weather. They may feel a little tighter if you are cold, but if it is uncomfortable, just take 'em out!
Q:How do you calculate density of the steel ball in grams per cubic centimeter?
The fact that they are pretty similar leads to the idea that Jupiter, too, is mostly H and He.
Q:Are oil and steel monopolistic competition?
While oil and steel may seem to be all the same, they are really not. There are many different grades of crude oil and many different types of steel.
