Q: I'm a big fan of stainless steel and sterling silver, but not of the humidity of the country I'm in. Therefore I sweat more. Gross, I know. I'm buying a necklace chain for my ring.So does sweat contribute to tarnishing of silver and steel? The real kind?: steel shouldn't really tarnish, it rusts and moisture increases that. Silver tarnishes when exposed to air and sulfur. Moisture increases the process a bit, but it happens anyway. Sweat is not gross, it's a necessary function of your body, otherwise you would die. A lot of sports people wear jewelry and they sweat a lot. If you wear the jewelry all the time, that will prevent the tarnish a bit. If you take it off, clean it (water and dish washing liquid), dry it and put it in a zip lock back to keep it away from air and moisture. In the end, cleaning the jewelry is quick and easy so don't worry about it.

Q: How are steel coils used in the production of automotive engine components?: Steel coils are used in the production of automotive engine components by being processed and shaped into various parts, such as pistons, crankshafts, and connecting rods. The coils are first cut, stamped, and formed into the desired shapes, and then undergo heat treatment and other machining processes to enhance their strength and durability. These components are crucial for the proper functioning of an automotive engine, as they provide structural support and help convert the energy generated by the combustion process into mechanical motion.

Q: I'v had 5 people at school say steel is stonger than Titanium and some(5) kids at school say titanium stronger then steel but i looked it up on the internet and i got soem web sites that say steel is stronger then titanium and some sites that say titanium is stonger then steel sooooo???? witch one is strongerPS i no tungsten is stronger then steel.... and titanium.................: This Site Might Help You. RE: is Titanium Stronger than steel?

Q: I believe steel is stronger but it steel lighter than iron too?: Steel is iron, with other things added that strengthen it and/or make it less rust liable. So, in general, steel is stronger than iron. In so far as the density, that depends on the steel alloy. Some are higher than iron, some lower. Remember there are hundreds of different steel alloys. edit: but the density is still close to that of iron. density steel 7750 to 8050 kg/m? density iron 7870 kg/m?

Q: What are the common coil diameters available for steel coils?: The common coil diameters available for steel coils vary depending on the specific industry and application. However, some of the most common coil diameters for steel coils typically range from 24 inches to 72 inches. These diameters are often used in various sectors such as automotive, construction, and manufacturing. It is important to note that the specific coil diameter required may differ based on factors such as the size and weight of the material being coiled, the equipment being used to handle the coils, and the specific requirements of the end-use application.

Q: Is there any other way of testing whether or not you have a 1944 Steel penny that won't damage the penny. The magnet test doesn't seem to work cause even when I try to get a 2007 penny to stick to the magnet...it won't. So is there some kind of magnet needed? Like power wise or anything like that, if not then I need to know what are other ways of testing the 1944 penny.: This Site Might Help You. RE: 1944 Steel Penny?

Q: In what ways can steel fail in use of buildings ad what can be done to prevent it?: First let us see what steel is made from. PIG IRON, which is put into a blast furnace with other things to get the impurities out. the very high grated of steed include TUNGSTEN CARBIDE STEEL, which is used to make tooling. down to lower grades of steel to make other things. the stronger the steel that is required the less impurities that are in it. different steels are treated with different elements depending on what the steel is going to be used for, So if steel is Incorporated into a building and say the building caught fire enough heat could be produced to actually soften the steel and result in failure. hope this helps.

Q: Corten steel tends to overheat in hot environments? (for example copper heats up under the sun): Weathering steel, best-known under the trademark COR-TEN steel and sometimes written without the hyphen as Corten steel, is a group of steel alloys which were developed to obviate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. Overheating ? It's not possible for a metal to get hotter than it's environment unless there is a source of radiation. The sun shining on a metal will heat up a bit, as will any material, but the amount is small and depends on the surface reflectivity. Define what you mean by overheating. .

Q: How did the growth of the steel industry influence the development of other industries?: At least three ways: 1. Steel as a material that other industries could use to do things that couldn't be done before (for example, construction (skyscrapers, long bridges, etc.)) or could now be done at much lower cost and hence increased the size of the industry (automobiles, bearings, etc.)

Q: What are the common welding defects in steel coils?: There are several common welding defects that can occur in steel coils during the welding process. These defects include: 1. Porosity: This is characterized by small holes or voids in the weld metal, which are caused by gas entrapment during the welding process. It can weaken the weld and make it more susceptible to corrosion. 2. Lack of fusion or incomplete penetration: This defect occurs when there is inadequate fusion between the base metal and the weld metal, or when the weld metal does not fully penetrate the joint. It can result in a weak or brittle weld. 3. Cracks: Cracks can occur in the weld metal or in the heat-affected zone (HAZ) of the base metal. They can be caused by factors such as high stress levels, improper cooling, or inadequate preheating. Cracks can significantly reduce the strength and integrity of the weld. 4. Undercutting: Undercutting is a groove or depression that forms at the toe of the weld due to excessive melting of the base metal. It weakens the weld and can lead to stress concentration and potential failure. 5. Excessive spatter: Spatter refers to the small droplets of molten metal that are expelled from the welding arc and can land on the surface of the steel coil. Excessive spatter can result in a rough or uneven surface finish and may require additional cleaning or grinding. To minimize these welding defects in steel coils, it is important to ensure proper weld preparation, including cleaning and removing any contaminants from the surface of the steel. Additionally, using the correct welding parameters, such as appropriate heat input and travel speed, can help to minimize defects. Regular inspection and quality control measures can also help to identify and address any defects before they become more serious issues.
