Q:What products can we make with steel (eg Steel strip, rod, bar, rail, tube) How are these made? What can we make from these steel products?Can you please make the answers as detailed as possible you can because i really want to know this really well. Thank you.: Your okorder (they make steel deck and steel joists) There are thousands of other items routinely produced from steel, including rebar, and all the metal in cars, airplanes, and about a million other things.

Q:How do steel coils compare to other materials in terms of cost?: Steel coils are generally more cost-effective compared to other materials due to their durability, versatility, and widespread availability in the market.

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:Is steel case ammo going to mess the gun up or is it just going to wear the parts out faster and if so how much faster? (I am not planning on reloading the rounds): First it is almost impossible to reload steel case ammo. It has Berdan primers, which are twice as hard to find re-prime with than regular 'Boxer' type primers. Steel case ammo, which is almost always laquer coated, will not be any more of a wear factor than brass cases, just don't leave a laquered round in a hot chamber, as the laquer will melt cause a jam when the round sticks in the chamber. Even with the price of components on the rise, I'd look into stocking up now! My reloads, including 7,62x39R's, are FAR superior to the surplus on the market, especially the steel-case, which I wouldn't shoot, myself. Once you have the brass cases, reloads are far cheaper than any surplus, to boot.

Q:What are the common transportation defects in steel coils?: There are several common transportation defects that can occur in steel coils. One of the most common is coil damage caused by improper handling or securing during transportation. This can result in dents, scratches, or even tears in the steel. Another common defect is coil edge damage, which can occur if the coils are not properly protected or if they rub against each other during transit. This can lead to deformation or even breakage of the coil edges. Additionally, coil shifting is another common defect, which happens when the coils are not properly secured or braced, causing them to move and shift during transportation. This can result in misalignment or damage to the coils. Finally, coil corrosion is a common defect that can occur if the coils are exposed to moisture or other corrosive elements during transportation. This can lead to rust and deterioration of the steel. Overall, proper handling, securing, and protection measures are crucial in order to prevent these common transportation defects in steel coils.

Q:What is the average price of a steel coil?: The average price of a steel coil can vary depending on factors such as the type of steel, size, and market conditions. It is best to consult with suppliers or industry reports for the most up-to-date and specific information on current average prices.

Q:What are the different methods of tension leveling for steel coils?: There are several methods of tension leveling for steel coils, including roller leveling, stretcher leveling, and temper leveling. In roller leveling, the coil passes through a series of rollers that apply pressure to remove the internal stresses and flatten the material. Stretcher leveling involves stretching the coil beyond its yield point to remove the unevenness and then allowing it to spring back to a flat state. Temper leveling uses heat treatment to relieve the internal stresses and bring the coil to a flat condition. These methods provide different ways to achieve a level and flat surface for steel coils.

Q:I am doing a project on how revolvers work and what materials they use and would like to know what specific grade of stainless steel they use for the manufacturing of the frame and cylinder?: *Rifle barrels are usually made from steel alloys called ordinance steel, nickel steel, chrome-molybdenum steel, or stainless steel, depending upon the requirements of the cartridge for which they are chambered. The higher the pressure and velocity of a cartridge (pressure and velocity usually go up together), the faster it will wear out a barrel. To give a satisfactory service life, barrels for high velocity cartridges must me made from tougher and harder steel than barrels for lower pressure cartridges. *The 400 (416) series SS commonly known as ordnance grade , is what barrels are made from . *If you want your barrel to be made from super alloy then it is 718 Inconel ,but a costly affair.

Q:How are steel coils used in the production of pipes and tubes?: Steel coils are an essential component in the production of pipes and tubes. They are used as the raw material to create the cylindrical shape of the pipes and tubes. The coils are unrolled and fed into a machine called a pipe or tube mill, where they undergo a series of manufacturing processes. First, the steel coils are unwound and straightened to remove any bends or twists. Then, the edges of the coils are trimmed to ensure they are smooth and even. This process is known as slitting. Next, the coils are passed through a forming machine, where they are bent into the desired shape. For pipes, the coils are bent into a circular shape, while for tubes, they can be formed into various shapes, including square, rectangular, or oval. Once the coils have been formed, they are welded together along the length to create a continuous pipe or tube. This welding process can be done using various techniques, such as high-frequency induction welding, electric resistance welding, or submerged arc welding. After the welding is complete, the pipes or tubes may undergo additional processes to improve their properties. These processes can include heat treatment, such as annealing or quenching, to enhance their strength or hardness. Finally, the pipes or tubes are cut to the desired length and may undergo further finishing processes, such as straightening, polishing, or coating, depending on their intended application. In summary, steel coils are used in the production of pipes and tubes as the starting material. They are unrolled, straightened, and formed into the desired shape before being welded together to create a continuous pipe or tube. These products can then undergo various additional processes to improve their properties and meet specific requirements.

Q:Why cold rolled stainless steel sheet is lower than cold rolled stainless steel coil?: Hello! The reason is: 1. cold rolled flat plate is Kaiping;2. cold-rolled plates are negative tolerances.
