Q:What is Light gauge steel? is it same with light weight steel?
guage means thickness.
Q:dangers of the steel factories?
All manufacturing jobs of that era were incredibly dangerous, even textile work, but steel work was likely the worst. Men would fall into vats of molten metal, be crushed under huge metal bars, hit by cranes, burned by simple contact with any of the red hot pieces of metal flying all around, and most commonly, die from asphyxiation or lung ailments from the constantly burning fires. Heat stroke was a big killer, too. There was virtually no form of compensation, either for injured workers, or, in the case of death, for their families. The Bessemer method, which Carnegie introduced into the US, was hoped to improve conditions...instead, it merely improved output, and Carnegie's factories after 1900 worked 200,000 men, twelve hours a day, on wages that barely kept their families alive.
Q:i know stainless steel don't rust, does that go the same for just regular steel..?
There are dozens of types of steels, some stainless and some not. They differ a lot in their chemical composition and in how they're made (especially heat treating methods). They all vary in their strength, working properties and corrosion resistance. Regular steel (technically carbon steel--mostly iron, with a little bit of carbon) rusts quite badly if unprotected and in the right environmental conditions i.e. humidity/moisture. The iron in regular steel reacts with oxygen to form iron oxide--the orange/red stuff we call rust. Iron oxide is a loose and porous material which provides no protection to the underlying steel, which is why rusted regular steel will continue to rust. Stainless steel, in addition to containing iron and carbon, contains chromium as a component--and it's the chromium that is important for corrosion protection. To be fair, even stainless steel rusts but what happens is that it's the chromium that reacts with oxygen to create a microscopically-thin layer of chromium oxide. This layer is very tough and actually protects the uncorroded steel, preventing further corrosion. Broadly speaking, the higher the chromium content, the more corrosion resistant the stainless steel.
Q:Why not use stainless steel to make coins?
Stainless steel has been used by some countries to make coins, but it's not an ideal metal. When a coin is struck, a die comes down and strikes the blank with many tons of force (the blank is also sitting on top of another die--one has the image on the obverse (front) of the coin, while the other die has the image of the reverse of the coin). When the die strikes the blank, the force causes the metal in the blank to flow into the recesses of the die. The problem with stainless steel is that it doesn't want to flow into the die. To get an image, either the relief (how high the raised portion of the design will be) has to be very low, and the coin has to have a simple design, or they have to greatly increase the pressure of the strike. This slows the coining press down, and greatly shortens the life of the dies.
Q:Will painted steel rust?
Rust is the process of steel oxidizing when in contact with oxygen, this reaction can be much fast if certain components are present, such as wet air or water. However, if the paint completely isolates the steel from the environment, the encompassed steel will never rust as long as paint shields it. Aluminum corrodes but it does not rust. Rust refers only to iron and steel corrosion. Aluminum is actually very prone to corrosion. However, aluminum corrosion is aluminum oxide, a very hard material that actually protects the aluminum from further corrosion. Aluminum oxide corrosion also looks a lot more like aluminum, so it isn't as easy to notice as rusted iron.
Q:what can i do to polish steel or iron?
If the steel knife is dark and not mirror-shiny, then it is probably carbon steel and not stainless steel. If they are carbon steel, then you cannot polish it to a mirror finish - sorry. If there's any rust on them, you can use a very-fine grit sandpaper to remove. Do not put carbon steel knives in the dishwasher, and dry them thoroughly after hand-washing. For long-term storage (meaning you don't plan to use the knife within the next few weeks), wipe the blade a bit with some mineral oil, then store the blade portion of the knife in a plastic bag.
Q:what is best cookware? stainless steel or iron?
Some utensils are both cookware and bakeware. The choice of material for cookware and bakeware items has a significant effect on the item's performance , particularly in terms of thermal conductivity and how much food sticks to the item when in use. Some choices of material also require special pre-preparation of the surface - known as seasoning - before they are used for food preparation. Stainless steel cookware is a great choice for safe cooking. Many kinds of cookware react with the foods, either changing the taste of the food or even releasing harmful materials into the food that can cause imbalances or diseases. Many non-stick coatings like teflon are safe - but once they get scratched or overheated they can start to leak chemicals in the food that are according to some scientific studies dangerous and possibly carcinogenic. Both the cooking pot and lid handles can be made of the same material, but will mean that when picking up or touching either of these parts oven gloves will need to be worn. In order to avoid this, handles can be made of non heat conducting materials, for example bakelite, plastic or wood. It is best to avoid hollow handles because they are difficult to clean or to dry.
Q:What is the difference between weldable steel and plate steel?
Weldable steel is a generic term for steel with low carbon content which makes it easy to weld, form, and machine. If you're looking for a knife blade material, you need either a stainless steel or a high carbon steel which is not at all weldable. The more carbon in steel, the better it responds to heat treatment like hardening, tempering, etc. Plus, the high carbon steel will hold an edge better. Hope this helped.
Q:Cast iron Vs. Stainless steel?
I would go with the stainless steel. I know that there was recently a study done that said that the non-stick material is slowly leaking the non-stick coating into your food. There is a problem with the copper and other metal pans as well. Slowly poisoning you throughout the years. As far as the cast iron, I am not totally sure that there are any problems with those. I haven't heard anything about them that is. I do know that cast iron gets hotter and cooks faster than the other metals. I hope I was able to help. Good luck.
