Q:What is the AISI grade of mild steel that is the most magnetic? What magnetic steels are the cheapest and easiest to buy?

Silicon steel is the most magnetic material for making into transformer cores and motor cores. It contains 1.25 to 2.5% Silicon. Silicon steel is usually rolled to 2mm plates as lamination material. Iron may be magnewtic but it has low resistivity. With high silicon alloyed to iron resistivity is increased and core and hysteres are losses reduced. Important silicon steels are designated as AISI M15, M19,M22 and M36. In ASTM, these steels are designated 36F15, 36F18 and many more.

Q:Went to top gun range in Houston, Tx. Guy there said no steel bullets..Anyone know why? Think i can shoot them anywhere else? Perhaps an outdoor gun range? The are monarch FMJ 9mm steel rounds..Thanks!

Indoor ranges and ranges that provide steel targets don't like them because of the additional wear and tear on their equipment. Some outdoor ranges don't allow them because they can strike sparks when they hit rocks and cause a fire. Others don't care. Best to call ahead or check the range's web site, if any, to see what they allow and don't allow.

Q:I'm looking for steel to make knives, but don't know what to get.

Buying good knifes now-adays is very difficult as most steel is made abroad and the quality is not the same as it used to be, British steel made in Sheffield used to rule the world but alas no more! so basically you get what you pay for, so you must be prepared to part with a substantialal amount of your hard earnt cash to get the best.

Q:How are steel coils shaped into specific forms?

Steel coils are shaped into specific forms through a process known as roll forming. This involves passing the coil through a series of rollers that gradually bend and shape the steel into the desired form.

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 challenges in coil leveling for high-strength steel?

Achieving optimal results in coil leveling for high-strength steel involves addressing several challenges. The steel's inherent hardness and strength present one of the main obstacles. High-strength steel is designed with enhanced mechanical properties, including tensile strength and hardness, making it difficult to deform and shape. To overcome the steel's high-strength nature, specialized leveling equipment is needed. This equipment must exert sufficient force to counter the steel's resistance to deformation. This may involve using stronger and more durable leveling rollers or increasing the pressure applied during the leveling process. Failing to apply the appropriate force can result in incomplete leveling, leading to residual stress and dimensional inaccuracies in the final product. Another challenge in coil leveling for high-strength steel is the potential for springback. Springback refers to the material's tendency to return to its original shape after being deformed. High-strength steel is especially prone to springback due to its higher elastic modulus. This can result in uneven leveling and dimensional variations in the coil. To mitigate springback, advanced leveling techniques can be utilized. These techniques include overbending and pre-bending the steel. Overbending involves bending the steel beyond the desired level, allowing it to spring back to the desired shape. Pre-bending, on the other hand, involves intentionally bending the steel in the opposite direction before leveling it, counteracting the effects of springback. These techniques require precise control and expertise to ensure accurate leveling. Additionally, high-strength steel often has a more pronounced yield point. The yield point is the stress level at which permanent deformation occurs. This can make it challenging to achieve consistent and uniform leveling throughout the coil. Proper adjustment of the leveling equipment and careful monitoring of the leveling process are necessary to effectively address this challenge. Furthermore, high-strength steel coils are often thinner and more sensitive to surface imperfections. Careful regulation of the leveling process is crucial to avoid causing damage to the steel surface, such as scratches or indentations. This may involve using softer leveling rollers or implementing protective measures, such as cushioning materials or coatings, to prevent surface defects. In summary, the challenges in coil leveling for high-strength steel revolve around its inherent hardness, springback tendencies, yield point behavior, and sensitivity to surface imperfections. Overcoming these challenges requires specialized equipment, advanced leveling techniques, precise control, and expertise to ensure accurate and high-quality leveling results.

Q:How do steel coil manufacturers manage inventory?

Steel coil manufacturers manage inventory by implementing various strategies and techniques. Firstly, they maintain a robust forecasting system to accurately predict demand and plan production accordingly. This helps in avoiding overproduction or stockouts. Additionally, they establish strong relationships with suppliers to ensure a steady supply of raw materials and reduce lead times. Inventory is carefully monitored using inventory management software, which tracks stock levels, identifies slow-moving or obsolete inventory, and enables timely reordering. Just-in-time (JIT) or lean manufacturing techniques are often employed to minimize inventory holding costs. Lastly, regular inventory audits and analysis are conducted to identify areas for improvement and optimize inventory levels for maximum efficiency and profitability.

Q:I am reading the book The Cure For All Advanced Cancers by Hulda Regehr Clark.She writes for example: cancer can be caused by exposure to heavy metals, like nickel and chromium from stainless steel cookware. Stainless steel cookware releases chromium and nickel, two of the most carcinogenic metals.Are there any studies done measuring how much nickel and cadmium can be released from the regular use of stainless steel cookware?Is this a commonly accepted opinion that use of stainless steel cookware is dangerous?If not stainless steel, what kind of cookware to use? I heard that non-stick cookware also releases some harmful chemicals.

Hi, I think that Stainless Steel is one of the safest ways to cook food. Glassware is also safe, but you must be careful not to drop the stuff, it can break and leave small pieces on the floor. Yes non-stick cookware can harm small fast breathing animals like birds in your house if the cookware overheats, but by keeping water or moisture in the bottom of the pan, and not using supper high heat, you can avoid overheating a non-stick surface. This also includes not scraping the surface with the utensils. Aluminum cookware, especially cast aluminum is considered by many as more than average toxic to many. Test for alltimers is that they contain aluminum in their bodies, and many owned aluminum cookware too. To kill cancer, look to Dr. Otto Warburg, who did win a Noble Prize for discovering how to kill the cancer cells.

Q:What is the difference between carbon steel and spring steel?? And which is the better one to make swords with??

All steel has carbon in it. If too much carbon is in the steel it is extremely hard and brittle. Like cast iron. The only difference between iron and steel is the level of carbon. Cast iron is very hard. A drill can barely drill thru it unless you treat it with something like cobalt or titanium nitride. But if you hit cast iron with a hammer very sharply it will break into pieces from the shock. Too low of carbon causes problems though. Steel is very flexible and machinable when it has very low carbon, but it also doesn't wear very well. If you made a sword out of low carbon steel, it would bend very easily and the edge would get dull quick. If you bent it, it wouldn't spring back either. That gets us to spring steel. This is just the right amount of carbon so the steel is very hard and the sword can hold an edge. It also gives it shock resistance. You can bend the sword and it returns to it's original shape. That is why it is called spring steel. The steel resists bending and when it does bend, as long as it isn't to far, it springs back when let go, to it's original shape

Q:Can steel coils be coated with RFID technology?

Yes, steel coils can be coated with RFID technology. The RFID tags can be securely attached to the surface of the steel coils, allowing for easy tracking, inventory management, and supply chain visibility.
