Brief Introduction
Cold Rolled Steel is steel thathas been worked below its recrystallization temperature by passing it between apair of rollers. Recrystallization temperature is the temperature at whichgrains in the lattice structure of the metal have been rearranged, leaving it freeof strain and deformations. Cold Rolled Steel is pre-treated before being coldrolled with a process known as pickling, which uses strong acids to removescale and other impurities. The Cold Rolled Steel is then passed throughrollers to reduce its thickness. Most cold rolling takes place in multiplepasses and as the size of the Cold Rolled Steel is further reduced, itsstrength and hardness both increase, but its ductility decreases. After coldrolling, heating the metal up in a process known as annealing can restore someof its ductility. The final Cold Rolled Steel may be manufactured in the formof sheets, strips, bars, or other forms.
Application
It’s widely used in outdoor andinterior decoration, furnishing manufacturing, home appliance, automobile etc.

- Q:How are steel coils used in the production of shipping vessels?
- Steel coils serve as a crucial ingredient in the manufacturing of shipping vessels. Typically crafted from high-strength steel, these coils are ideal for fabricating the ships' hulls and other structural elements. In the shipbuilding process, the steel coils undergo an initial unrolling and cutting phase, where they are fashioned into specific sizes and shapes in accordance with the ship's design. These pre-cut pieces are then joined together through welding or bolting, forming the vessel's framework. This framework provides the necessary sturdiness and rigidity to withstand the unforgiving conditions of the sea. Additionally, steel coils are employed in the creation of decks, bulkheads, and various internal components of the shipping vessels. Molded into different sections, these coils are subsequently assembled and affixed to the ship's structure. The utilization of steel coils in these areas guarantees longevity and resistance to corrosion, which are vital for the overall durability and safety of the vessel. Moreover, steel coils find application in the production of ship propellers, rudders, and steering mechanisms. These components play an integral role in controlling the ship's movement and direction. The utilization of high-strength steel coils ensures the requisite robustness and dependability, facilitating smooth and efficient navigation. In summary, steel coils occupy a pivotal position in the manufacturing of shipping vessels. They provide strength, durability, and corrosion resistance, and are incorporated into various aspects of ship construction, ranging from the hull to the decks, bulkheads, and internal components. Absent steel coils, the production of shipping vessels would face significant challenges, resulting in ships lacking the necessary structural integrity to navigate the seas safely and efficiently.
- 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:what do you think about producebility of low density steel? for example: can density of 1020 steel (or ony others) be decreased without any loss of other properties.
- If a material has a lower density than steel, then it isn't steel.
- Q:What we have to keep in mind before buying a steel building?
- Before okorder /... Hope this will prove helpful to you.
- Q:How are steel coils packaged for shipping?
- Steel coils are typically packaged for shipping by being tightly wound and secured with steel bands or straps. They are then placed on wooden pallets or in steel cradles to ensure stability during transportation. Additionally, protective packaging materials such as plastic or cardboard may be used to prevent damage from moisture, dust, or other external factors.
- Q:What are the common coil edge finishes?
- Some common coil edge finishes include slit edge, mill edge, and deburred edge.
- Q:How are steel coils used in the manufacturing of transmission shafts?
- Steel coils are used in the manufacturing of transmission shafts by being converted into cylindrical shapes through a process known as coil winding. These coils are then cut, shaped, and machined to create the desired dimensions and specifications for the transmission shafts. The high strength and durability properties of steel make it an ideal material for transmission shafts, ensuring efficient power transmission and overall performance of the machinery.
- Q:is cold roll or hot roll mill roller is cast steel? or cast iron?
- Casting is a process of forming a part just like forging or rolling are also processes of forming steel. Cast steel can be any grade of steel poured into a sand mold to form a part like a water pump housing in your car. To be classified as steel, the mixture usually contains less than 2% carbon. Cast iron is a mixture that generally contains more than 2% carbon. It also can be poured into a sand mold. There are many grades of iron. Many metals can be cast into shapes like the air intake plenum on your car is probably cast aluminum. Bronze statues are made by pouring molten bronze into a mold. The process used to create a part has an effect of that part's mechanical properties. A casting is weaker than a forging but certain parts cannot be formed by forging. The large diameter rolls used in steel mills to roll steel into thinner plates or sheets is a hot rolled steel that has probably been forged into shape then machined into the final diameter. Some rolls are fabricated from hot rolled steel plates into shape. This allows the ability to add internal cooling paths to keep the roll from overheating.
- Q:How are steel coils inspected for defects after rewinding?
- Steel coils are inspected for defects after rewinding through a thorough visual examination and various non-destructive testing techniques such as ultrasonic testing, magnetic particle inspection, and eddy current testing. These methods help identify any surface defects, internal flaws, or deviations in dimensions, ensuring the quality and integrity of the steel coils.
- Q:i am working a client.my vendor specified in pipe specification pipe line class as MS1 (code for Mild steel)but assigned material to this code is cs smls astm A 106B.my question is any difference between CS and MS material?pls suggest me
- *Carbon steel, also called plain carbon steel or Mild Steel, is steel where the main alloying constituent is carbon. The AISI defines carbon steel as: Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0.40 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60. If it crosses limit as said, it will come under alloy steel. ASTM A 106 gr B is a carbon steel pipe and seamless Pipe for High Temperature Service. So, it will be a mild steel comes under carbon steel category.
