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: When and where did soldiers wearing steel protective helmets start ?It seems to have been common by the start of WW1

- Q: What are the dimensions of a steel coil?
- The dimensions of a steel coil can vary depending on its intended use and manufacturer. However, typical dimensions include a width ranging from 600mm to 2,200mm, a diameter of 600mm to 2,000mm, and a weight ranging from a few hundred kilograms to several metric tons.
- Q: i have a guitar with three nylon three steel strings. Am i able to replace the nylons with steel strings?
- Depends okorder Classical guitars aren't able to handle the tension of steel strings for the most part. Be careful with deciding which type and gauge string to put on certain guitars.
- Q: What is the minimum order quantity for steel coils?
- The minimum order quantity for steel coils can vary depending on the supplier and specific product. It is recommended to contact the supplier directly to inquire about their minimum order requirements for steel coils.
- Q: I made a wood crossbow body but all I need is a bow which I want to be metal. I've used a thin steel sheet that I cut to appropriate size but when it bent with the string strung, it never went to original shape after being shot. I used a slightly thicker and it wouldn't bend at all. Anybody know what thickness and type to use? Any real answers are very appreciated. Thanks.
- You are trying to use plain carbon steel which only can be bent a little bit if it is to return to its original shape. You have to use spring steel or high carbon steel that is intended to be bent a lot and still recover to its original shape. Most people making crossbows with metal bows get a piece of steel from a leaf spring of a vehicle and grind it to shape. A steel bow cross bow almost always needs a very strong trigger mechanism and a miniature wench to pull the steel bow string into position. You might be better off making the bow of wood.
- Q: What are the different grades of steel used in coil manufacturing?
- There are several grades of steel used in coil manufacturing, including low carbon steel, high carbon steel, stainless steel, and alloy steel. Each grade has its own unique properties and is chosen based on the specific requirements of the application, such as strength, corrosion resistance, or heat resistance.
- Q: Is it possible that stainless steel watches get rust. Any experience? Thanks.
- Stainless Steel comes in many different grades, a prime example is to see if a magnet sticks to it if so it has a high iron content as the grade of the stainless increases its magnetic ,iron properties decrease have you ever left a stainless knife, fork, spoon in a kitchen sink for a few days it will show evidence of rusting most jewelery is low grade stainless as it does not need to to be suitable for medical grade or marine grade quality under normal conditions wearing your stainless steel watch will not make it rust however if you were to leave that watch in contact with another metal and they are wet then yes it will rust as it will create a chemical reaction.
- Q: Is there a difference between hot rolled and cold rolled steel coils?
- Yes, there is a significant difference between hot rolled and cold rolled steel coils. Hot rolled steel coils are produced at high temperatures and are typically used for applications that require malleability and ductility. On the other hand, cold rolled steel coils are produced at room temperature and undergo a process that results in a smoother, more precise finish. Cold rolled steel coils are often used in applications that require a higher degree of strength and surface quality.
- Q: Can i make holes in iron and steel with somekind of drill bit. All i have is metal drill bits. Mabey like 68 of them but i dont know wich one to use and if they will penetrate.
- Drills are used to make holes in steel all the time.
- Q: what is the porpose of preheating mild steel prior to welding
- ok dont listen to bob the builder down there, u preheat thicker steels to draw moisture out of them. take a propane torch to something exposed to just atmospheric air around 3 inches thick and the water will literally pour out of it. do u want that in ur weld? no. so u preheat to draw any moisture or contaminates out of the base metal. good luck.
