Q:Guns, Germs, and Steel?
i dont really understand this question but if it means to how it was before then it was absent because the native americans were not into technology so they obviously had no guns created that was something that they had traded to get from europe as for the germs i ddo not know about thta really except for if it means that common disease and one of the diseases most used in history books is malaysa from mosquitos but when they had traded with europe they got all sorts of diseases now for steel the only reason i remember them traveling for is for gold and i dont remember them ever looking for it until 13 colonies were established as you can see im not exactly sure about germs and steels but i know that the guns part is correct
Q:Is carbon steel a type of alloy?
Carbon steels are alloys. This is evident in the carbon-iron phase diagram:
Q:Question about the strength of steel..?
Gary is right on! To add to it some rebar is heat treated if you weld it it loses the heat treating if you don't re heat treat it it will fail at the welded joint.
Q:Good steel toe motorcycle boots?
You don't need steel toes in a motorcycle. The top of the foot isn't where the danger comes from when injured in a motorcycle accident. Where you need the most protection is in the ankle and heel. The ankle twists and the heel and calf bang on the ground. You need some protection at the toes, but that is from the road impacting the toes and grinding against the boots as you slide. Any boots made for motorcyclists will do. Stay away from steel toed work boots - they are designed for a job site, not a motorcycle crash.
Q:Does mild steel rust?
Mild steel is an alloy. It is the most common form of steel. Mild steel (a so-called carbon steel) is a general term for a range of low carbon (a maximum of about 0.3%) steels that have good strength and can be bent, worked or can be welded into an endless variety of shapes for uses from vehicles (like cars and ships) to building materials. The carbon does not stop the material rusting or corroding. In addition to iron, carbon, and chromium, modern stainless steel may also contain other elements, such as nickel, niobium, molybdenum, and titanium. Nickel, molybdenum, niobium, and chromium enhance the corrosion resistance of stainless steel. It is the addition of a minimum of 12% chromium to the steel that makes it resist rust, or stain 'less' than other types of steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide, called the passive film. The sizes of chromium atoms and their oxides are similar, so they pack neatly together on the surface of the metal, forming a stable layer only a few atoms thick. If the metal is cut or scratched and the passive film is disrupted, more oxide will quickly form and recover the exposed surface, protecting it from oxidative corrosion.
Q:Is Steel crystalline in its makeup?
Steel is crystalline. In general the bigger the crystals the better.
Q:What are the brands that sell 100% stainless steel cookware(interior and exterior)?
You do not want 100% stainless steel cookware, because it's a poor conductor of heat. All high quality stainless cookware is layered with stainless steel only on the exterior and interior surfaces, while having at least an internal heat spreading core of aluminum or copper. Not all stainless steel is sufficiently ferrous (magnetic) to work with electric inductive cooktops, so some stainless cookware adds an additional layer of ferrous steel in addition to the thermal cores. You also wouldn't want a slow cooker that's 100% stainless steel, because the uneven heating would cause food to burn more quickly. They are usually made of ceramic stoneware for a reason, even heating. Besides, a stainless pressure cooker (with alum/copper) core can in less than an hour everything a slow cooker does in 3+ hours, with better flavor, color, and nutritional content. By the way, the Prestige stainless cookware isn't 100% stainless, of course, and that's a GOOD thing.
Q:Why was there molten steel at Ground Zero?
that's just it: there wasn't very much molten steel for the very reason you point out. Jet fuel burns at 800° to 1500°F. This is not hot enough to melt structural steel. However, engineers say that for the World Trade Center towers to collapse, their steel frames didn't need to melt, they just had to lose some of their structural strength. Steel will lose about half its strength at 1,200 degrees F. The steel will also become distorted when heat is not a uniform temperature. after the collapse, a LOT of folks took a look at the remains. the result was the conclusion that the fire caused the central core of the building to weaken. When the floors collapsed one on top of the other, the weight was too much for the weaked core to bear, causing the result we are all familiar with. hope this helps
Q:stainless steel appliance?
Baking soda mixed with liquid dish soap can make a good paste to gently rub on stains. Be sure to rinse the stainless steel surface thoroughly, and towel dry. If the stains still remain you can try vinegar. Remember to thoroughly rinse and towel dry. If stains still remain I recommend trying a stainless steel cleaner and polisher. Barkeeper's Friend is a good powder formula that can clean without scratching. Be sure to follow the directions, rinse thoroughly, and towel dry. These methods should help remove the discolorations
Q:how can one go about melting and casting steel?
Steel is melted in a cupola furnace. you don`t cast rods you cast a large ingot and then while its red hot and still soft it is rolled in between gradually reducing shaped rollers so it gets stretched out and the structure of the metal makes it less likely to snap.
