Cold Rolled Steel is steel that has been worked below its recrystallization temperature by passing it between a pair of rollers. Recrystallization temperature is the temperature at which grains in the lattice structure of the metal have been rearranged, leaving it free of strain and deformations. Cold Rolled Steel is pre-treated before being cold rolled with a process known as pickling, which uses strong acids to remove scale and other impurities. The Cold Rolled Steel is then passed through rollers to reduce its thickness. Most cold rolling takes place in multiple passes and as the size of the Cold Rolled Steel is further reduced, its strength and hardness both increase, but its ductility decreases. After cold rolling, heating the metal up in a process known as annealing can restore some of its ductility. The final Cold Rolled Steel coil may be manufactured in the form of sheets, strips, bars, or other forms

Q: I understand that damascus sword steel was made by folding the strip of steele double , reheating, hammering, folding again and so forth hundreds of times. Was this the same or very nearly the same techmique the japs used making the sword blades the samari swords?(forgive the misspelling): Folded Damascus Steel

Q: All the appliances in my kitchen are stainless steel, and I hate how they look becuase every time I wash them they are full of streaks. Is there a good cleaner made for stainless steel that won't leave streaks?: Stainless Steel Appliance Cleaning Stainless steel kitchen appliances look best when they're clean and shiny. To clean tough stains and cooking grease, and give them a dazzling shine, try the same detergent you would use when washing the dishes. One formulated to cut grease works especially well.This also works well for general kitchen cleaning.Waterless hand soap also works great as a polish, simply rub on, and polish - no rinsing.=)

Q: many sword sellers sell swords made of 440 and stainless, i know those are both totally **** for real swords. so are 1045, 1060, or 1095 good grades of steel for a sword?: Carbon Steel is the most common, while most live-steel(designed for use) ready sword utilize on of the spring steels you mentioned. Hybrid steel like those used in the Slayer series seem neigh-indestructible. The steel should be strong enough to not notch on a strike, but flexible enough to flex when you bend it, lest it shatter on a hard blow.

Q: How are steel coils processed and treated?: To ensure the quality and suitability of steel coils for different applications, they undergo a series of steps and treatments. Initially, the coil is uncoiled by removing its protective wrapping and unwinding it. Any defects like cracks or uneven surfaces are then inspected. Next, the coil is cleaned to eliminate dirt, oil, and rust using chemical agents and mechanical scrubbing. After cleaning, it is rinsed and dried to prevent corrosion caused by residual moisture. Once cleaned, the steel coil may be treated based on its intended use. One common treatment is pickling, where the coil is immersed in an acidic solution to remove impurities and scale. This improves the surface finish and prepares the steel for further processing. After pickling, the coil can undergo cold rolling, which reduces its thickness and improves dimensional accuracy. This is done by passing the steel through a series of rollers at room temperature, gradually decreasing thickness and increasing strength. It also improves the surface finish. In some cases, the coil may undergo additional heat treatments like annealing or tempering. Annealing involves heating the coil to a specific temperature and slowly cooling it to relieve internal stresses and improve mechanical properties. Tempering, on the other hand, involves reheating the coil to a lower temperature and rapidly cooling it to enhance strength and toughness. Once the desired processing and treatments are completed, the steel coil may be coated or painted for added protection against corrosion or to enhance its appearance. Coating processes can include hot-dip galvanizing, electroplating, or applying organic coatings like paint or powder coatings. Finally, the processed and treated steel coils are cut into specific sizes or shapes according to customer requirements. This can be done using cutting methods such as shearing, slitting, or sawing. Overall, the processing and treatment of steel coils involve cleaning, pickling, rolling, heat treatment, coating, and cutting processes. These steps are carefully carried out to ensure the quality, strength, and suitability of the steel for its intended applications.

Q: Why are properties of steel not identical?: Steel is manufactured to different specs. To match the needs of its intended end use .Tensel strength,Hardness, Corosion resistance etc. The chemical make up will change to suit.

Q: How are steel coils processed and shaped into various products?: Steel coils are processed and shaped into various products through a series of manufacturing processes. First, the steel coil is uncoiled and cleaned to remove any impurities. Then, it goes through a process called leveling, where the coil is flattened and straightened. Next, the steel is cut into the desired length or shape, using techniques like shearing or slitting. After that, it may undergo additional processes such as forming, bending, or rolling to give it the desired shape. Finally, the steel is often treated with coatings or finishes to enhance its durability and appearance.

Q: What is the role of steel coils in the production of pipes and tubes?: Steel coils play a crucial role in the production of pipes and tubes as they serve as the primary raw material. These coils are unwound and undergo various processes such as cutting, bending, and shaping to form the desired pipe or tube shape. The steel coils provide the necessary strength, durability, and structural integrity to the final product, ensuring that pipes and tubes can withstand high pressure, corrosion, and other demanding conditions.

Q: Can steel coils be coated with anti-corrosive substances?: Yes, steel coils can be coated with anti-corrosive substances. Coating the coils with anti-corrosive substances provides an additional layer of protection, preventing or slowing down the process of corrosion and extending the lifespan of the steel coils.

Q: How do steel coils compare to stainless steel coils?: Steel coils and stainless steel coils are both used in various industries, but they differ in their composition and properties. Steel coils are typically made from carbon steel, which is strong and durable but susceptible to corrosion. On the other hand, stainless steel coils are made from an alloy of iron, chromium, and other elements, which provides them with excellent corrosion resistance. Stainless steel coils also have a higher resistance to heat and oxidation, making them suitable for applications that require superior durability and hygiene standards. Overall, stainless steel coils are generally considered to be of higher quality and more suitable for applications where corrosion resistance is crucial.

Q: Can steel coils be used in the production of automotive parts?: Yes, steel coils can be used in the production of automotive parts. Steel coils are commonly used in the manufacturing of various automotive components such as body panels, chassis parts, springs, and engine components due to their strength, durability, and formability. The coils are processed and shaped into the desired automotive parts using various techniques such as cutting, stamping, welding, and forming.
