Q: Why does steel with several composites have a greater hardenability from quenching than low carbon steel alloys?Any help would be great
Bit tricky to explain and I don't know muh about it but steel on its own has lost of gaps in it ( the molecular structure) and when carbon is added thos gaps are filled, I think of it like this: it is easier to punch through expanded polystyrene( with all the little balls) than unexpanded(just a lump of plastic) as the balls are not properly joined and have air pockets between them.
Q: In construction, what types of stress require steel to be placed in footings?
Shear and bending stress.
Q: What are the environmental benefits of using steel coils?
There are several environmental benefits of using steel coils. Firstly, steel is a highly recyclable material, meaning that it can be reused multiple times without losing its properties. This reduces the demand for raw materials and minimizes waste. Additionally, steel coils have a long lifespan, making them durable and resistant to wear and tear. This reduces the need for frequent replacements, saving resources and reducing waste. Furthermore, steel is a highly energy-efficient material, both in its production and during its use. It requires less energy to manufacture steel coils compared to other materials, and its high strength-to-weight ratio allows for lighter structures, reducing energy consumption in transportation. Overall, the use of steel coils contributes to a more sustainable and eco-friendly approach in various industries.
Q: What is the standard length of steel coils?
The standard length of steel coils can vary depending on the industry and specific requirements, but common lengths range from 30 feet to 60 feet.
Q: How are steel coils protected during transportation?
Steel coils are kept safe and free from harm during transport through a range of precautionary measures. One widely used technique involves utilizing top-notch packaging materials like heavy-duty plastic wrap or waterproof paper. These materials form a protective shield against external factors such as moisture, dust, and debris. Moreover, steel coils are typically placed on wooden pallets or skids to elevate them from the ground and prevent direct contact with surfaces that may cause scratches or dents. To provide further protection, the coils are securely fastened to the pallets using strong, corrosion-resistant metal strapping or bands. This ensures that the coils remain in position and do not shift or move during transport, significantly reducing the risk of damage. Additionally, specialized equipment like coil cradles, coil racks, or coil bunks are used to load and secure the steel coils onto flatbed trailers or shipping containers. These devices are specifically designed to firmly hold the coils in place and evenly distribute their weight, preventing any stress or strain during transit. Apart from physical safeguards, steel coils may also undergo various surface treatments before being transported to prevent corrosion. This may involve applying a protective coating or oiling the coils to create a barrier between the steel and the surrounding environment. This process is particularly important when the coils are exposed to adverse weather conditions or long shipping durations, as it helps to prevent rust or other forms of corrosion. In conclusion, a combination of appropriate packaging, secure fastening, and proper loading techniques are employed to ensure the safety of steel coils during transportation. These measures guarantee that the coils arrive at their destination without significant damage.
Q: This question is directed to anyone who has played or know someone who plays a lap or pedal steel guitar.I've been a guitarist for about 8 years now and have played a variety of styles from rock, fingerstyle/classical, singer/songwriter acoustic stuff, ect, and now I've really had an interest in learning how to play a lap steel or pedal steel guitar. I am completely new to the instrument(s), so I'm seeking all the information I can. I do know that a pedal steel is a lot more expensive, so I'm probably looking to start on a lap steel for now. Basically how should I get started? Should I find a cheap lap steel at a pawn shop or purchase something new? Are there any good method books out there? I'm a pretty experienced guitarist, so should I expect to get the hang of it quickly? Is there much of a market for a lap/pedal steel player? haha.Also, I am left handed. How much trouble would it be to re-string a steel guitar? Or would I be better off getting a left-handed model?
Hello okorder / I'm not familiar with the brand...it's certainly not commonly played....but it has the features you need for a starter guitar.
Q: How do steel coil manufacturers handle customer complaints?
