- Q:What are the common coil lengths available for steel coils?
- The steel coil lengths offered in the industry and specific requirements are subject to variation. Nonetheless, several standard coil lengths are extensively employed in different applications. These encompass coil lengths of 100 feet (30.48 meters), 200 feet (60.96 meters), 300 feet (91.44 meters), and 500 feet (152.4 meters). These lengths find extensive use in construction, manufacturing, and automotive sectors, where steel coils serve diverse purposes. It is worth mentioning that coil lengths can also be tailored to meet specific project requirements or customer preferences.
- Q:what is the chemical process that makes steel harder when it is heated and cooled rapidly?what does the heating of it do to the atoms?what does the cooling of it do to the atoms?what makes tempered steel so strong compared to untempered steel?
- You can't temper all steels. Generally the material must be a high-carbon or tool steel. Different alloys temper differently, and tempering is usually done to get a specific set of characteristics, so you must know what you are working with and use the right methods and temperature. If you do it wrong, the material may be hard but too brittle for the purpose or have other issues. It can be simple, such as heating to a dull red, carbonizing the surface (use an acetylene rich flame until it blackens the surface) and oil quenching. Do that to a piece of tool steel (like a screwdriver) and it will case (surface) harden it to the point you can't scratch it with a file. Tempering changes the way the molecular structure in the metal is linked and oriented.
- Q:How are steel coils used in various industries?
- Steel coils are used in various industries for their durability and versatility. They are commonly used in automotive, construction, and manufacturing industries for making structures, machinery, and appliances. Steel coils are also utilized in the energy sector for producing power generation equipment and in the transportation industry for making ships and railcars. Overall, steel coils play a significant role in providing strength and reliability in a wide range of industrial applications.
- Q:How are steel coils used in the manufacturing of cables?
- Steel coils are used in the manufacturing of cables as they provide strength and support to the cable structure. The steel coils are typically used as armor or reinforcement, helping to protect the cables from external elements and maintain their structural integrity.
- Q:I have a steel plate 3' long x 2 wide x 3/16 thick. I have a 1/2 diameter hole with the center 3/4 from the end. Tensile strength is 38,000psi. A chain goes through the hole and is connected to a load. how does one determine how much tension the chain can have before it rips through the hole?
- Assuming that the chain can take the breaking load of the plate, the plate will fail at the area between the hole and the end, in double shear. The shear strength of the material should therefore be known for us to be able to calculate the breaking force. Approximately, the shear strength of steel is about 60% of the tensile strength. For ordinary mild steel the tensile strength is about 60,000 psi, not 38,000 psi. 38,000 psi is just about the yield point of mild steel. Using 60,000 psi tensile strength, the approximate shear strength of steel therefore is 36.000 psi. The net area between the hole and the end of the plate is: A = 3/16(3/4 - 1/4) = 0.09375 in^2 The force necessary to rip through the area which is also the tension on the chain is: T = 2 x 0.09375 x 36,000 = 6750 lbs
- Q:How are steel coils processed into finished products?
- Steel coils are processed into finished products through a series of steps that typically include uncoiling, leveling, cutting, and shaping. After uncoiling, the steel coils are passed through a leveling machine to remove any unevenness. Then, they are cut into specific sizes and shapes using different cutting techniques such as shearing or slitting. Finally, the cut steel pieces are shaped through various processes like bending, welding, and machining to produce the desired finished products.
- Q:how do i quinch steel? i heard instead of water oil will actually make it harder... wat ways are best for wat steels? and how do i tell wat kind of steel i have?... i will be doin this with my poket knife..
- boy what a though question ! let me explain. when you rapidly cool a steel from high temperatures(depending on steel type) with water or oil or other means , it is called quenching. it depends on the steel type to say if it is better to quench it with oil or water but basically in water you will have a harder steel rather than oil. for some steels if you do this you will ruin it's properties ! you can't totally tell what kind of steel do you have until you get it analyzed with Quantometer analyzer with a pocket knife it is more like an estimation and it can't be trust able generally if you can scratch the steel with your knife it means it is not a hard steel and it might not be expensive. I hope that helps but for more information i need to know more !
- Q:Obviously this is an easy question for anyone who works with metal. However, I am currently writing a book and had an idea that had to do with these two metals. Is it possible for gold to be folded into steel while it is being forged? Do 3-metal alloys exist? If this is not possible with current metal-working techniques and technology, what would be needed to make it possible? And finally, what exactly would the mixing of these two yield? A weak metal? A brittle metal? How would it compare to iron or gunmetal? If you have no idea, please offer speculations. Thank you!

- Q:What are the different types of steel coil surface treatments for outdoor applications?
- There are several types of steel coil surface treatments suitable for outdoor applications. These include galvanization, which involves coating the steel with a layer of zinc to protect against corrosion; zinc-aluminum alloy coating, which provides enhanced corrosion resistance; paint coating, which adds a layer of protective paint to the steel surface; and organic coating, which uses a polymer-based material to protect against weathering and corrosion.
- Q:How are steel coils priced and traded in the market?
- Steel coils in the market are priced and traded based on a variety of factors. The primary determinant is the current dynamics of supply and demand in the steel industry. When demand for steel coils is high, prices tend to increase, and vice versa. The cost of raw materials, such as iron ore and coal, is another crucial factor in determining the price of steel coils. Fluctuations in the prices of these materials can directly impact the pricing of steel coils. Furthermore, the price of steel coils is influenced by their quality and specifications. Coils with desirable characteristics, such as strength, corrosion resistance, or surface finish, may command a higher price in the market. Steel coils are traded through different platforms, including physical exchanges, futures contracts, and over-the-counter (OTC) markets. Physical exchanges allow buyers and sellers to trade steel coils by exchanging physical deliveries. Futures contracts, on the other hand, enable traders to buy or sell steel coils at a predetermined price and future date, providing a way to hedge against price fluctuations. The OTC market provides an alternative avenue for trading steel coils, where buyers and sellers negotiate and agree on prices directly without involving a formal exchange. This allows for flexibility and customization in trading, catering to specific requirements. In conclusion, the pricing and trading of steel coils in the market are influenced by factors such as demand and supply dynamics, raw material costs, quality specifications, and the availability of different trading platforms. It is a complex process that requires careful consideration of various factors to determine fair prices and facilitate efficient trading.
