Q: What is the minimum thickness of a steel coil?: The specific grade and type of steel being used, along with the manufacturing process, can cause the minimum thickness of a steel coil to vary. Generally, a steel coil is typically about 0.001 inches (0.0254 millimeters) thick. It is worth mentioning that this value is a general rule and may change depending on the industry's or application's specific requirements and standards.

Q: Recently I bought Bleach's Grimmjow's replica sword from swordsswords and I was wondering how strong is 440 steel when used for a 21 inch blade? Can it cut effectively? Is it dangerous?: You were seriously ripped off. I own a 440 stainless sword that I paid $29 for on eBay. It ain't a half bad sword actually, and like you said, I have never failed to cut straw mats with it. The 440 stainless is about as good as you can get without paying for a folded steel katana. However, I also own a Bugei company folded steel katana and the difference is night and day. The balance is better, the edge is incredible (you could literally shave with it) and there's just something....ELSE. There's a different FEEL. It's like the difference between using a tool and a weapon. As far as the shingami, again, you were ripped off. You can buy a traditional shingami from eBay and actually get it from a reputable company and not take your chances with the stuff you find at a mall. Even then, you will only pay maybe $50-$75 for a good set including shipping. Generally speaking, nothing you get from a mall or COULD get from a mall will be as good as something from a reputable company like Bugei. However, like in the case of your katana, some things might be good ENOUGH for you. However, you do need to look around and do some price checking before you drop that much money for anything. Hope this helps... Sensei Cox

Q: How are steel coils stored?: Steel coils are typically stored in warehouses or outdoor yards. They are usually stacked on top of each other, either horizontally or vertically, with wooden or steel dunnage to prevent damage and ensure stability. Coils may also be stored on specialized racks or on coil cradles. Proper spacing and organization are crucial to facilitate easy access, minimize the risk of damage, and ensure efficient inventory management.

Q: How are steel coils classified based on their thickness?: Steel coils are classified based on their thickness into different categories such as light gauge, medium gauge, and heavy gauge.

Q: My company want to welding stainless steel, do not know to use what welding machine?: Stainless steel is a fascinating metal to weld. Welding stainless can be difficult if you don't know what you are doing. It reacts to excessive heat by warping and distorting once it cools. Everything shows up in stainless. If you weld with too much heat you can see it by the heat marks left in the metal along with any distortion. It also scratches very easily so you must take care when welding on a metal table. Stainless steels can be welded using several different procedures such as shielded metal arc welding, gas tungsten arc welding, and gas metal arc welding but stainless steel welding wires have been developed for welding stainless steels.

Q: What are the dimensions of steel coils used in the transportation equipment industry?: The dimensions of steel coils used in the transportation equipment industry can vary depending on the specific application and manufacturer. However, commonly used dimensions range from 0.015 inches to 0.625 inches in thickness and from 24 inches to 60 inches in width. The outer diameter of these coils typically falls within the range of 48 inches to 72 inches.

Q: I just want regular steel, not stainless steel.: If it rusts, magnetic, hard, heavy with high melting point I reckon yourve found mild steel.

Q: What are the common welding defects in steel coils?: There are several common welding defects that can occur in steel coils during the welding process. These defects include: 1. Porosity: This is characterized by small holes or voids in the weld metal, which are caused by gas entrapment during the welding process. It can weaken the weld and make it more susceptible to corrosion. 2. Lack of fusion or incomplete penetration: This defect occurs when there is inadequate fusion between the base metal and the weld metal, or when the weld metal does not fully penetrate the joint. It can result in a weak or brittle weld. 3. Cracks: Cracks can occur in the weld metal or in the heat-affected zone (HAZ) of the base metal. They can be caused by factors such as high stress levels, improper cooling, or inadequate preheating. Cracks can significantly reduce the strength and integrity of the weld. 4. Undercutting: Undercutting is a groove or depression that forms at the toe of the weld due to excessive melting of the base metal. It weakens the weld and can lead to stress concentration and potential failure. 5. Excessive spatter: Spatter refers to the small droplets of molten metal that are expelled from the welding arc and can land on the surface of the steel coil. Excessive spatter can result in a rough or uneven surface finish and may require additional cleaning or grinding. To minimize these welding defects in steel coils, it is important to ensure proper weld preparation, including cleaning and removing any contaminants from the surface of the steel. Additionally, using the correct welding parameters, such as appropriate heat input and travel speed, can help to minimize defects. Regular inspection and quality control measures can also help to identify and address any defects before they become more serious issues.

Q: Is a steel plate the same as a steel coil?: You must have an open book and a flat plate, and it is a little bit harder to cut the parts than the plate.

Q: Hi can someone help me pleaseis there any available data for mechanical behaviour of recycled steel, i need to compare them with new steel.: It is not clear from the question whether the recycled steel is used in its existing state or used as raw material for further fabrication. For the existing steel, you need to track down the original documents such as the ladle analysis and mill certificates certifying the material standards for which the steel was fabricated. Another alternative is take samples and conduct chemical and mechanical tests on the steel. Also the date of when the structure was built from which the steel is recycled may help indicate whether it is (American Society for Testing and Materials) Standard ASTM A7 or ASTM A36 or another type of steel. In most cases, the steel is used as raw material to make new steel. The mill will adjust the additives to produce steel with the required chemical and physical properties to meet the ASTM standards specified.
