Q:How are steel coils used in the manufacturing of construction equipment?

Steel coils are used in the manufacturing of construction equipment as they serve as the primary raw material for creating various components such as frames, chassis, and heavy-duty structures. These coils are often cut, shaped, and welded to form the necessary parts, providing strength and durability to the equipment. The malleability and strength of steel make it an ideal material for construction equipment, ensuring their ability to withstand heavy loads and harsh working conditions.

Q:I bought a steel pendant on eBay, but it turned out to be too shiny.I've read on a couple forums that if I leave it soaked in urine for 2 days, it will get duller.Now, if it really does get duller, will the pendant get rusty afterwards?So is the shiny surface the only thing that prevents it from rusting?Any simple, non-urine ideas on how to make it duller are welcome too.Thanks!

Stainless steel will rust under proper conditions. I live on a boat on salt water, trust me. If the urine works it won't be prone to rusting any more than before. It's not the shine that inhibits rusting with stainless steel, it the % of carbon in the steel, compared to regular steel. IF the urine works it's because it is acidic (a mild acid). Wash it with a small brush and some baking soda to neutralize the acid when your done. A much stronger acid would be swimming pool acid. (Muriatic acid) but be careful you might test a spot with a Q tip on the back. If you try Muriatic acid it would take seconds.Then wash in baking soda water to remove all acid.. SS

Q:This needs to be in a percentage by mass. Could you please also reference where this info has come from. Thanks.

Steel is produced in different grades,depending on the amount of iron, and chromium, and any other alloying metal that might be in that particular grade. Any good welders hand book would be a good source of information on steel and its properties.

Q:How are steel coils used in the production of metal containers?

Due to their versatility and strength, steel coils find wide application in the production of metal containers. Each stage of manufacturing metal containers relies heavily on steel coils. To begin with, steel coils serve as the primary raw material for metal container production. These coils consist of high-quality steel that is rolled into a continuous sheet, ensuring consistent thickness and durability. Subsequently, this sheet is cut into specific widths and lengths according to the container size requirements. Once the desired dimensions are achieved, various techniques are employed to shape the steel coils into container form. Roll forming, for example, is a commonly used method where the steel coil passes through a series of roll dies that gradually shape it into the desired container shape. This technique allows for the creation of containers in different sizes and designs, ranging from cans and drums to large industrial containers. After the initial forming process, the steel coils undergo further processing to enhance their strength and durability. Heat treatment is one such process where the coils are exposed to high temperatures to increase their hardness and resistance to wear and tear. Additionally, annealing and quenching methods may be employed to improve the steel's properties. Once the containers are formed and processed, additional fabrication steps, such as welding or sealing, are carried out to ensure their structural integrity. Steel coils are frequently utilized in these processes as they provide a robust and dependable material for creating sturdy seams and joints. Finally, metal containers receive various coatings or treatments to protect them from rust, corrosion, and other environmental factors. Steel coils can be coated with materials like paint, epoxy, or zinc to enhance their resistance to these elements, ultimately ensuring the longevity of the containers. In conclusion, steel coils play a crucial role in the production of metal containers. They serve as the primary raw material, aid in forming, processing, and finishing, and provide the necessary strength, durability, and versatility required for manufacturing reliable metal containers across a range of industries.

Q:What are the different grades of steel used for manufacturing coils?

Manufacturing coils requires the use of various grades of steel, each selected for their specific properties and suitability for different purposes. Some commonly used grades include low carbon steel, high carbon steel, stainless steel, galvanized steel, and alloy steel. Low carbon steel, also known as mild steel, is a cost-effective option with good formability. It is ideal for applications that require low strength and high ductility, such as automotive components and construction materials. High carbon steel is characterized by its exceptional strength and hardness. It is commonly employed in the production of coils that demand high tensile strength, like springs and wires. Stainless steel, an alloy with a high chromium content, offers corrosion and oxidation resistance. It is often utilized in the manufacturing of coils for the food industry, medical equipment, and automotive applications. Galvanized steel, on the other hand, is steel coated with a layer of zinc to safeguard it against corrosion. It is frequently used in the production of coils that will be exposed to harsh environmental conditions or require excellent durability, such as roofing materials and electrical appliances. Alloy steel, formed by adding elements like manganese, nickel, chromium, or molybdenum to carbon steel, exhibits improved strength, hardness, and resistance to wear and corrosion. It finds wide application in industries that necessitate high strength and toughness, such as aerospace and automotive. Choosing the appropriate grade of steel is crucial to ensure optimal performance and longevity of the coils, as it is essential to match the specific requirements of the application.

Q:iam talking abt carbon steel of composition:-C=0.15wt% Mn=0.60wt% P=0.035wt% S=0.04wt% Cu=0.20 (min)wt%....

The composition you mention is not a low carbon steel.The carbon and manganese content are high enough to mean that the crystal grain size will be small. A very large grain size is needed in steels for transformers,motors etc.The large grain size and lack of carbides in low silicon steels for magnetic purposes allows the easy movement of magnetic domain walls.Transformer steels typically have a carbon content of about 0.003% and 3.5%Si with the phosphorus and sulphur at a tenth of the levels you mention.The high Si content increases the electrical resistivity of the magnetic core and reduces the power loss from eddy currents(the core metal has voltages generated in it by the changing magnetic fields) and the power lost in eddy currents heats up a transformers core so it needs extra cooling;the loss is inversely proportional to the resistivity and 3.5%Si increases resistivity of iron by a very large amount.The presence of high silicon with ultra low carbon and manganese level allows the soft magnetic steels to be annealed at very high temperatures(850 to 1100deg C)without a phase change so that the crystals have 10,000 to 10,000,000 times the volume of the crystals in heat-treatable (Just)steel you mention.Fine for playing with and demonstrating electromagnetism but not as electrical engineering feedstuff.

Q:If needed for Defence could a stainless steel sword kill someone my buddy wanted this sword for Defece after it is sharpend here is a picture

Ya it could kill someone if it was sharpened enough but from experience stainless steel swords don't get as sharp as Carbon or higher grade steel. Not to mention it would probably bend if you hit someone with it all the way. Hell the one I let some people who were chopping a bush ( just a normal bush ) they were playing around and it got bent. I'm going to say I can't suggest a stainless steel sword for anything other then handing on your wall. Not even going into the whole If you use a sword for self defense is it considered self defense? debate. It's a sketchy situation not to mention you would need training with a sword to actually use it without it just getting brushed off.

Q:My teacher says if they were that they would still be standing today. I'm not sure if he means the reinforced steel in the concrete beams, columns etc or if the whole beams and columns floor etc were were made of reinforced steel.

There is no way you could make a 110 floor building out of concrete.
