Product Description

Brief Introduction
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:How are steel coils used in the manufacturing of agricultural structures?: Steel coils are used in the manufacturing of agricultural structures as they provide the necessary strength and durability required for building structures such as barns, grain storage facilities, and equipment sheds. These coils are often used to fabricate beams, columns, and trusses, ensuring structural stability and resistance to harsh weather conditions. Additionally, steel coils are also used in the production of agricultural machinery and equipment, further enhancing the efficiency and reliability of farming operations.

Q:What are the common packaging methods for steel coils?: The common packaging methods for steel coils often involve using steel strapping or plastic banding to secure the coils, followed by either placing them on wooden pallets or loading them into steel crates for transportation and storage. Additionally, protective materials such as cardboard or stretch film may be used to prevent damage and ensure the integrity of the coils during shipping.

Q:What are the common standards and specifications for steel coils?: There are several common standards and specifications for steel coils that are widely recognized and used in the industry. Some of the most common ones include: 1. ASTM A36/A36M: This specification covers carbon structural steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction. 2. ASTM A572/A572M: This specification covers high-strength low-alloy columbium-vanadium structural steel shapes, plates, sheet piling, and bars for applications in bolted, riveted, or welded construction. 3. ASTM A653/A653M: This specification covers steel sheet, zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) by the hot-dip process. 4. ASTM A1011/A1011M: This specification covers hot-rolled, carbon, structural, high-strength low-alloy, high-strength low-alloy with improved formability, and ultra-high strength steel sheet and strip in coils. 5. JIS G3302: This Japanese Industrial Standard specifies the requirements for hot-dip zinc-coated steel sheet (galvanized steel sheet) and strip. 6. EN 10111: This European standard specifies the requirements for continuously hot-rolled low carbon steel sheet and strip for cold forming. 7. ISO 3575: This International Organization for Standardization standard specifies the requirements for hot-dip zinc-coated and zinc-iron alloy-coated steel sheet and strip. These are just a few examples of the common standards and specifications used for steel coils. It is important to note that different industries and applications may have specific requirements, so it is always advisable to consult the relevant standards and specifications for the specific application.

Q:How are steel coils protected from condensation?: Steel coils are typically protected from condensation by applying a thin layer of oil or another corrosion-resistant coating to the surface. This acts as a barrier, preventing moisture from coming into direct contact with the steel and minimizing the risk of condensation forming. Additionally, the coils are often stored in a controlled environment with proper ventilation to minimize humidity levels and prevent condensation from occurring.

Q:I got my dog those nice looking stainless steel water and food bowls (looks great next to my kitchen appliances...haha). The thing is my dog will drink from the toilet or a plastic bowl but not out of his bowl...I was wondering if those stainless steel bowls change the taste of food and water?: Personally I use stainless steel for my own dogs because ti is easy to keep clean, and doesn't weigh too much when I am carrying 3 large bowls full of food. Plus when I drop them they don't break. The only reason I don't use plastic is because my dogs like to chew anything plastic :P I use plastic for my foster cats and foster puppies and have never had any sort of infection. Personally I think that is some sort of myth as I have never known anyone's pet to get an infection from a plastic bowl. As long as you keep them clean, plastic or stainless are both fine

Q:My musical saw has, despite my best efforts, got little patches of rust on it. How Do I go about removing the rust without spending too much on rust-removal products and without affecting the properties of the steel?: I would suggest rust removal by electrolysis. Search youtube for that. It probably will not affect the metal but there are no guarantees. I would run a test on another metal. Also this process can be dangerous because hydrogen gas is a by-product - remember not to smoke or be cooking nearby! The Easy way is with BlackStar Rust Remover. It will turn the metal black and convert the rust to metal which can then be painted or left black.

Q:did bible stated that steel is coming from outer space. i mean meteor rocks that enter our earth sistem contains the minerals iron.: steel is manufactured from iron ore and coal in furnaces and it is not found in raw state in nature

Q:Hi my dad bought a stain steel refridg. yesterday, and we went to clean it and it looks all streaky and gets finger prints and stuff on it too easily we used mr clean multisurface cleaner and it didnt work to well is there a certain type of cleaner we are supposed to use?: I use a good car wax/chrome polish

Q:What are the dimensions of steel coils?: The dimensions of steel coils vary depending on factors such as the specific type of steel, the intended use, and industry standards. Generally, steel coils can range in width from a few inches to several feet, with thicknesses typically ranging from a fraction of an inch to several millimeters. The inner diameter of a steel coil can also vary, with common sizes being 20 inches and 24 inches. Ultimately, the dimensions of steel coils are determined by the specific needs and requirements of the end user.

Q:A steel rod AISI 1040 has the ultimate tensile strength Sut of 113 kpsi. Determine the rotating bending specimen's endurance limit S'e at 10 to the 6th cycles.: A rule of thumb for endurance limits of steel with Sut 200 ksi is that S'e = 0.504 x Sut, thus for your case that would be 113 x .504 = 56.95 ksi (endurance limit is defined as fatigue life greater than 10^6 cycles)
