- Q: I asked a question last week about stainless steel and got some great answers. I combed all over the internet to try to figure this one out but could not find anything. What resists bending better: chrome vanadium steel (i.e. a steel commonly used to make tools) or stainless steel 304. My guess would be the chrome vanadium alloy but thats just a guess. Which on resist's bending better and by how much (#'s please :-)). Also, if anyone knows if chrome vanadium steel is cheaper than stainless steel 304 that would be awesome? I can't find a price per pound on chrome vanadium steel anywhere! Please help. Thanks in advance-Josh
- Type 304 stainless steel can be tempered to give tensile strength up to about 125,000 psi. There are many chrome vanadium alloys, and tempers, but they are generally very hard steels used for machine tools which are used to cut other steels. They generally are much stronger, and can be hardened up to tensile strengths of 250,000 psi and beyond. (Bending strength is proportional to tensile strength, but Cr-V steels are not usually used for beams or other structure members.) Cr-V steels are specialty alloys and will probably be a good bit more expensive per pound than common stainless alloys. For any steel, price depends on the form you are buying, i.e. plate, bar, or other shape, as well as the alloy and temper specified, and the quantity. You need to get prices from a supplier. You can find some online catalogs, but you usually have to call the vendor for price info.

- Q: How are steel coils protected against bending and deformation?
- Various measures are implemented to safeguard steel coils from bending and deformation. One prevalent approach entails employing protective packaging materials, such as wooden crates or metal skids. These materials provide stability and support, effectively preventing any bending or deformation during transportation or storage. Additionally, steel coils are frequently tightly secured using steel or plastic bands. This measure serves to maintain their shape and prevent any shifting or movement. These bands are strategically positioned at regular intervals along the length and width of the coils, guaranteeing even pressure distribution and minimizing the risk of bending or deformation. Furthermore, steel coils can be further shielded by placing them on a flat and level surface during storage or transportation. This practice ensures the even distribution of weight, thus reducing the likelihood of bending or deformation due to uneven pressure. In certain instances, steel coils may also be coated with anti-corrosion agents. This protective coating shields against moisture and rust, which can weaken the structural integrity of the coils and lead to bending or deformation over time. In conclusion, the combination of appropriate packaging, secure fastening, and careful handling is paramount in safeguarding steel coils against bending and deformation. This comprehensive approach ensures the maintenance of their structural integrity and quality.
- Q: What are the different grades of steel coils?
- There are various grades of steel coils available, including low carbon steel, medium carbon steel, high carbon steel, stainless steel, and galvanized steel coils. Each grade has specific properties and applications, making them suitable for different industries and purposes.

- Q: How are steel coils inspected for straightness?
- To ensure compliance with quality standards, steel coils undergo a variety of methods to inspect their straightness. Among these, visual inspection is commonly employed, wherein trained inspectors meticulously examine the coil's edges, surface, and overall shape for any visible flaws or irregularities that might indicate a lack of straightness. An alternative approach involves measuring the coil's straightness using precise instruments. This entails taking measurements at different points along the coil's length and comparing them to specified tolerances. Accurate assessment of the deviation from the desired straightness is achieved using techniques like laser measurements or straightness gauges. Moreover, certain coils undergo non-destructive testing, such as magnetic particle inspection or ultrasonic testing, to uncover any internal defects or stresses that may impact their straightness. These tests are capable of identifying hidden flaws that visual inspection alone may fail to detect. Additionally, some manufacturers employ automated inspection systems that leverage advanced technologies like computer vision or artificial intelligence. These systems swiftly scan the coil's surface and analyze it for any deviations from straightness, generating precise measurements and ensuring consistent quality. In summary, the inspection of steel coils to verify their straightness involves a combination of visual inspection, precise measurements, non-destructive testing, and advanced technologies. These methods work together to identify any deviations from the specified straightness, ensuring that only coils meeting the required standards are utilized in various applications.
- Q: What are the common methods of inspecting steel coils for quality control?
- Steel coils are inspected for quality control purposes using various methods. These methods involve visual inspection, dimensional measurement, and non-destructive testing. To inspect steel coils, visual inspection is a commonly used and straightforward method. This entails visually examining the surface of the coils for any visible defects such as scratches, dents, or discoloration. Visual inspection also includes checking the labeling, packaging, and identifying signs of corrosion or damage. Another crucial method to ensure quality is dimensional measurement. This involves measuring different dimensions of the coils, such as thickness, width, and length, to ensure they meet the required specifications. Tools like calipers, micrometers, or laser measurement devices can be utilized for dimensional measurement. Non-destructive testing (NDT) techniques are also widely employed in steel coil inspection. NDT methods enable the detection of internal and surface defects without causing damage to the material. Ultrasonic testing is a common NDT technique used for steel coil inspection. It works by sending high-frequency sound waves through the coil and analyzing the reflected waves to identify any defects. In addition, magnetic particle testing and dye penetrant testing are used to detect surface cracks or defects in the coils. Apart from these methods, other quality control practices may include chemical analysis to ensure the steel's composition meets the required standards, mechanical testing to assess the strength and hardness of the material, and corrosion testing to evaluate the coils' resistance to corrosion. In summary, a combination of visual inspection, dimensional measurement, and non-destructive testing techniques is typically employed to ensure the quality and integrity of steel coils during the quality control process.
- Q: Why can't you use a lead shot only choke with steel shot or a steel shot only choke with lead shot? I have used a lead only choke with steel shot and my shotgun shot fine and there was no damage to the choke.
- You should not have done this. It not a matter of shooting fine - it's a question of getting the correct distance and shot pattern SAFELY. Lead only chokes squeeze the lead shot a considerable bit. Lead is compressive and soft - it takes more squeeze to get the correct patterns from a shotgun. Steel only chokes do not squeeze as much as the lead version because the steel is very had and does not compress well. When you accidentally shoot lead through a steel chock the pattern will be weird. But, it usually is not an unsafe condition. However, steel through a lead choke will cause unsafe pressure at the choke and can explode. You end up with a bugs bunny/road runner cartoon looking shotgun! Most gun shops all over the USA are decorated with these blown up shotguns from people doing exactly what you did. Unless you want to add yours to the other dead gun collection in some shop - I recommend you take your shotgun and all your chokes into a gun smith and have him look it all over. See if anything is out of tolerance. Guns are not fool proof. If you do not follow the instructions and operate them safely they will blow up and tear a piece of your body off. Just ask any ER doctor or long time shooter.
- Q: How are steel coils manufactured?
- Steel coils are manufactured through a multi-step process that involves heating and shaping steel slabs, followed by passing them through a series of rolling mills to reduce their thickness and increase their length. The coils are then cooled, inspected for quality, and finally, wrapped and ready for shipping.
