- Q: Is the product of mild steel environmentally friendly? does it produce any emissions?The same question for leather aswell.
- Steel just rusts, it doesn't produce any emissions just sitting there. They even make architectural steel called Corten to rust to a nice patina. If you consider how the steel was made in the first place, a great big NO! Steel making requires massive amounts of electricity plus it gives off some nasty fumes in the liquid state. Leather itself doesn't emit much of anything, but the dyes might. Again though, if you look at how it's made, tanning leather is right up there with steel mills and paper mills for pollution, some of the worst.
- Q: I want to experiment with making steel and want to especially make it stronger. And also I want to know if its possible to turn a meteorite into steel?
- If you really want to do this, you should be getting some books on steel metallurgy rather than asking on Yahoo. ASM sells a Metallurgy for the non-metallurgist that would be a good introduction. Most university libraries will have the full ASM handbook that includes detailed information for different grades of steel (vol 1), heat treatment and surface hardening (vol 4), testing (vols 8-12), and casting (vol 15). A reference for continuous cooling transformation diagrams will also help in designing a heat treatment process. If you want to make something stronger than most commercial steels, you'll need to get into nanotechnology and unconventional steel processing methods like powder metallurgy. You can increase the strength of steel by about 1000% by reducing the grain size from 50 micron (typical for conventional processing methods) to 100 nm (achievable through high-energy ball milling). Though you'd also need to customize the chemistry to stabilize the grain size during the necessary thermal processing, I believe zirconium works well with iron.
- Q: How are steel coils inspected for thickness and width accuracy?
- Steel coils are inspected for thickness and width accuracy using non-destructive testing methods such as ultrasonic testing and laser measurement systems. Ultrasonic testing involves sending high-frequency sound waves through the coil, and by analyzing the reflected waves, the thickness of the steel can be determined. Laser measurement systems use lasers to scan the width of the coil, providing precise measurements. These inspection methods help ensure that steel coils meet the required thickness and width specifications.
- Q: Can steel coils be coated with UV-resistant materials?
- Yes, steel coils can be coated with UV-resistant materials. This coating helps protect the steel from the harmful effects of ultraviolet (UV) radiation, such as fading, discoloration, and degradation. UV-resistant coatings are commonly used in various industries to enhance the durability and longevity of steel coils, particularly when exposed to outdoor or high UV environments.
- Q: How are steel coils used in the manufacturing of industrial machinery?

Recycled steel can be used to produce new coils, reducing the need for raw material extraction and minimizing environmental impact. This circularity in the use of steel coils supports the aerospace industry's efforts towards a more sustainable and environmentally friendly manufacturing process. In conclusion, steel coils play a vital role in the aerospace manufacturing industry by providing the necessary materials for aircraft structures and components. Their strength, durability, cost-effectiveness, and recyclability make them a valuable resource, ensuring the safety, reliability, efficiency, and sustainability of aircraft production.
- Q: If steel can rust with saltwater... then why are ships made of steel? can't we just use other metals like aluminium etc?
- aluminium is not good in saltwater Steel rusts in fresh air let alone saltwater but its alot cheaper than other mass produced metals you can rivet or weld it cheaply unlike stainless steel or Aluminium We could make them of wood but thats been tried Glass fibre and plastic is good for small boats but to do and Aircraft carrier size ship i doubt it
- Q: What are the common storage defects in steel coils?
- Some common storage defects in steel coils include: 1. Staining or discoloration: If steel coils are not stored properly, they can be exposed to moisture or chemicals, leading to staining or discoloration. This can affect the appearance and quality of the steel. 2. Rust or corrosion: Steel is susceptible to rust and corrosion if it comes into contact with moisture or is stored in a humid environment. Rust can weaken the steel and compromise its integrity. 3. Coil deformation: Improper stacking or handling of steel coils can result in deformation or bending. This can occur when coils are stored on an uneven surface or subjected to excessive pressure or weight. 4. Surface damage: Steel coils can develop surface scratches, dents, or abrasions if they are mishandled during storage. This can be caused by improper stacking, handling, or transport of the coils. 5. Edge damage: If steel coils are not properly protected or secured during storage, the edges can become damaged. This can include chipping, cracking, or bending of the edges. Edge damage can affect the usability and safety of the steel coils. 6. Coil slippage: When steel coils are not securely stored or stacked, they can slip or roll off, causing damage to the coils themselves and potentially causing harm to nearby personnel or equipment. 7. Contamination: Steel coils can become contaminated if they are stored near or come into contact with substances such as dirt, oil, grease, or chemicals. Contaminants can affect the quality and performance of the steel. 8. Coil nesting: Inadequate spacing or stacking of steel coils can result in coil nesting, where one coil becomes embedded or nested within another. This can lead to damage to the coils, making them difficult to separate and use. To prevent these common storage defects, proper handling, storage, and protection measures should be implemented. This includes storing steel coils in a dry, well-ventilated area away from moisture and chemicals, using appropriate stacking and support structures, and providing adequate protection against impacts and contaminants. Regular inspections and maintenance should also be conducted to identify and address any potential defects or issues.
- Q: so my parents gave me stainless steel cookware for christmas and the first time i used it i cooked chicken. it stuck to the pan and where the oil splattered it cooked on and turned it dark black and brownish. and the bottom too. i don't cook with it because i don't want to burn it on anymore but i don't know how to clean it. how do i cook without burning anything, aside from a lower flame and how on earth do i get the stains on. i've tried almost everything too! thanks.
- Dear pwrgrlmanda, I also use stainless steel. I have found the best way to clean any cookware that has food baked or cooked on it is by filling my sink with the hottest water possible, submerging the entire piece of cookware in the sink and then liberally sprinkling cascade powder over the top. Allow it to set overnight and usually in the morning everything will come off with a nylon scrubber. It really works! No more elbow grease. This also works for corning ware, glass baking pans, cookie sheets etc. Hope it works for you.
- Q: How are steel coils used in the manufacturing of seat belts?
- Steel coils are used in the manufacturing of seat belts as they provide strength and durability to the webbing material. These coils are typically inserted within the seat belt fabric to enhance the belt's ability to restrain occupants during a collision. The steel coils absorb and distribute the force exerted on the seat belt, ensuring it can withstand high impact forces and provide reliable protection to passengers in vehicles.
