Q: I'm looking for a good source as to the 'structural formula' of steel. I'm not quite sure if that's what it's actually called, but here's a link to what I'm looking for.: There is none. There is no steel molecule, so one can't draw its molecular structure. Most steel has a body-centered cubic (ferrite) crystal structure (some stainless steels are face-centered cubic - austenite). Depending on the alloying elements, it's typically a random solid solution. Most of the lattice sites will be occupied by iron atoms, but other atoms from the alloying components will replace random sites. Smaller atoms like carbon are in the interstitial points, meaning they fit in between the larger atoms. Depending on the alloy and the processing conditions, you can also get a mix of phases, including more complex structures like cementite (iron carbide), molybdenum carbide, manganese sulfide, or martensite (a non-equilibrium tetragonal phase).

Q: All the steel straps that secure my deck and stair 6x6 posts to the concrete piers have some rust on them. Had bought a rust reducer to spray on them and repaint. As I went to do this I found that one of them is on its last legs, with the steel rusted through and bubbling up all up the sides of the straps. Since this is the end post on a row of 3 deck support posts, I was thinking of removing as much rust as possible, then paint with Rustoleum and cover lower post with something to keep water away from post and pier in the future? Was thinking of something removeable so I could check on it for further rusting. What do you folks with building experience think of this? Thanks.: If these steel straps are rusting through and on their last legs, a coat of paint is going to be cosmetic at best. Replace these straps with new ones. The originals were either very poorly galvanized, or you live someplace with a very corrosive environment. In any event, paint can't save this sort of thing. Steel brackets serve a real purpose, and after they're weakened, they can't do that anymore. How would your home hold up in an earthquake, for example? What you're proposing doesn't sound safe.

Q: i need some ideas of what material could replace iron or steel to make fridges, stoves, dishwashers, tractors, aircrafts, cars and buses and anything else that is made of iron and steel. anything is greatly appreciated as at the moment i have no idea what to put down.: Material selection is a complex area. Iron and steel are very good materials in terms of their strength, stiffness and hardness (especially when compared to their density to give specific strength/stiffness. They are also relatively cheap and the economics of material selection is often the over-riding criteria. Each individual substitution has to be considered on the merits of what the component has to do and the environment in which it operates and often to replace steel with, say, aluminium, might not be appropriate or might require a redesign of the component to accomodate the lower strength and stiffness. Take one of your examples of a dishwasher; To replace the (cheap and thin) steel outer casing with aluminium would require thicker sheet to achieve the same stiffness. To replace the stainless steel inner you would need a corrosion resistant material (which rules out aluminium) which can be easily fabricated to shape. Nickel alloys would be harder to process and very expensive, but you might be able to use a bronze alloy. If you have time look in the library for a book on materials selection by Ashby - one of the best texts on the subject.

Q: How are steel coils used in the manufacturing of engine components?: Steel coils are used in the manufacturing of engine components as they provide a strong and durable material for various parts. These coils are typically processed and shaped into specific components such as pistons, crankshafts, cylinder heads, and connecting rods, which are vital for the proper functioning of an engine. The high strength and heat resistance of steel make it an ideal choice for these critical components, ensuring the engine's reliability and performance.

Q: How much do steel coils weigh?: The weight of steel coils is subject to variation, which is determined by multiple factors including coil thickness, width, length, and the particular type of steel employed. In general, steel coils can range in weight from a few hundred pounds to several tons. It should be emphasized that the measurement of steel coils typically revolves around their weight per unit area, referred to as the "basis weight" or "coil weight".

Q: What are the common surface defects in steel coils?: Steel coils commonly have surface defects, including scratches, pits, indentations, stains, and rust spots. Scratches may occur due to mishandling or processing, and their depth and length can vary. Pits are small depressions caused by impurities in the steel or during manufacturing. Indentations are similar but larger and more noticeable. Stains can result from chemicals, water, or other contaminants coming into contact with the steel. Rust spots form when the steel is exposed to moisture or corrosive elements, leading to iron oxide formation. These defects can impact the appearance, quality, and performance of the steel, necessitating their resolution to ensure the intended use of the coils.

Q: i recently got an industrial piercing and instead of getting pierced with a metal bar i have a PTFE bar .. i eventually want to put in a metal bar but what kind do i get? whats the difference between a surgical steel and titanium bar?thanks: Titanium Industrial Barbell

Q: I need to penetrate steel on my car but don't know which bit to use. Are there special bits for steel?: Yes, they'll be marked HSS, High Speed Steel.

Q: How are defects in steel coils repaired?: Defects in steel coils are repaired through various methods depending on the type and severity of the defect. Common repair techniques include grinding, welding, soldering, or using heat treatment processes to correct the defects. The specific approach is determined by professionals after assessing the nature of the defect and considering the desired quality and performance standards of the steel coils.

Q: I wrote in my assignment that mild steel has a high carbon content (4%).This is why it has its strong and rigid properties.. is this correct?: Steel is defined as an alloy of iron and carbon (often supplemented by further materials) with a carbon content between 0.01 % and 2.06 %. 4% is in the realm of cast iron, which isn't quite as rigid as steel. Mild steel contains 0.16 - 0.29% carbon. You're off by more then a decimal.
