Q:Apparently, this has to do something with electrochemical cells.

Steel wool is a mild abrasive. I don't know what it is you are cleaning, but it is probably to remove any coating or oxidisation from the metal. Maybe you are using a metal for an electrode (perhaps a steel nail pushed into a lemon?).

Q:I live in the Black Hills and I need to re-side my cottage. I like the look of vinyl. I've heard pros and cons about both steel and vinyl. Is steel really that easy to dent? It just doesn't look as 'clean' as vinyl. Also what 3 color combos do you like? My cottage has shutters.

I have steel siding, and it is a pain in the butt. It's much harder to keep clean than vinyl. As for color combos, I love mine, sunny yellow with off white trim, and brick red for the doors. I added new brushed chrome doorknobs and brushed chrome rails around the porch, and it looks awesome. I am planning to have the steel siding replaced with vinyl though.

Q:Correct me if I am wrong, but steel is an alloy between iron and carbon. Does the carbon in the steel stops the iron from rusting or corroding? Also what is the difference between mild steel and stainless steel?

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:I want to buy steel. My problem is i purchase it from a middle man, so i need to know what MIld steel is. What it's real name or specifications is/are. I dont want to end up purchasing Black steel or other stuff i can sell or use...

I wonder from your phrasing if you are referring to pipe or tubular steel. Seamless Black usually are terms used when referring to pipe. Mild steel is low carbon steel, easy to machine, form, weld. It has lower strength than medium or high carbon steels. AISI 1018 is probably the most common. If this middle man cannot provide any specifications, maybe you need a new source.

Q:Can one assume that stainless steel that can be hardened is magnetic?

Most of the 300 series stainless metals are not magnetic, but if it is cast, it is magnetic. Welds are considered casting, so the welds are magnetic even though the items that are welded together are not. The 400 series stainless may have a few types that are magnetic. I suppose generally the hardenable factor has a bearing if you consider that 400 series can be hardened more readily than the 300 series. Source: Working in metal fabrication shops.

Q:a steel abr sells for about 879 now...a mith just over 1kany suggestions on which-keyword WHICH steel item to make-which is the best-exp wise, and steel bar conservative wise.

If members, cannonballs. If not, steel kites, I suppose. Steel Platebody only alchs for 1200, and requires 5 bars... But I stuck with steel, till 70 smithing... cheaper, and requires less coal to make....

Q:gigantic navy ships made of steel float, why??

Concrete boats also float, Capt Johns link explains that. It is area + weight + volume. Displacement. Buoyancy is achieved by Displacing fN or X.

Q:Hi can someone help me pleaseis there any available data for mechanical behaviour of recycled steel, i need to compare them with new steel.

It is not clear from the question whether the recycled steel is used in its existing state or used as raw material for further fabrication. For the existing steel, you need to track down the original documents such as the ladle analysis and mill certificates certifying the material standards for which the steel was fabricated. Another alternative is take samples and conduct chemical and mechanical tests on the steel. Also the date of when the structure was built from which the steel is recycled may help indicate whether it is (American Society for Testing and Materials) Standard ASTM A7 or ASTM A36 or another type of steel. In most cases, the steel is used as raw material to make new steel. The mill will adjust the additives to produce steel with the required chemical and physical properties to meet the ASTM standards specified.

Q:They both sell the same thingIf prices are to high companies won't by the steelIf prices are to low then the steel company won't earn enoughWhy are some steel companies more successful than others

Steel is a global commodity. There is some variety in product (flat rolled, tubing, etc), but basically the same product worldwide. Cost to the customer includes shipping of a very heavy product. Inputs are also heavy and costly to ship. Inputs: - Coal - Iron Ore. Some firms have the ability to recycle old steel, a competitive advantage. - Energy (very energy intensive industry) - Labor - Machinery. A new blast furnace is more efficient than 50 years old. So the most profitable steel firms have some of these characteristics: - Proximity to raw materials - Proximity to customers - Access to cheaper means of transportation; rail and sea - Newer machinery - Cheaper labor force - Reasonable cost for electricity and fuel for furnaces

Q:How are steel coils used in the production of automotive frames?

Steel coils are used in the production of automotive frames as they provide the necessary strength and durability. These coils are typically formed into specific shapes and sizes, which are then welded together to create the frame structure. The high tensile strength of steel coils ensures that the automotive frame can withstand the various stresses and strains experienced during vehicle operation, ensuring safety and stability.
