- 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: Can solution annealing be done on carbon and low alloy steels. please give an explanatory answer.
- No. Carbon steel has two different crystal structures, FCC and BCC , depending on the temperature. when you heat steel up and then quench it, it locks the crystal structure into the BCC form. this makes it hard. whereas precipitation hardened austentic stainlesses remain BCC regardless of the temp, so the hardness change is not a function of thermally induced strain. you can anneal carbon steel but the thermal profile is closer to the precipitation profile of PH stainlesses than it is to the Solution annealing profile.
- Q: What are the main factors that affect the flatness of steel coils?
- The main factors that affect the flatness of steel coils include the quality of the raw material used, the thickness and width of the coil, the temperature and humidity during the manufacturing process, the tension applied during coiling, and the cooling and leveling processes employed.
- Q: What are the common coil widths and thickness combinations available for steel coils?
- The common coil widths and thickness combinations available for steel coils vary depending on the specific requirements and industry standards. However, there are some standard sizes that are commonly available in the market. For coil widths, the most common standard sizes range from 600mm to 2000mm. These widths are widely used in various industries such as automotive, construction, and manufacturing. However, custom widths are also available to meet specific project needs. As for the thickness combinations, steel coils are typically available in a range of thicknesses. The most common thicknesses for steel coils are between 0.4mm and 3mm. However, thicker or thinner options are available depending on the specific application. It is important to note that these standard sizes and thickness combinations may vary based on the specific steel grade, manufacturing process, and the supplier's capabilities. It is always recommended to discuss the required specifications with the supplier or manufacturer to ensure the availability of the desired coil widths and thickness combinations.
- Q: What are the common uses of pre-painted steel coils?
- Pre-painted steel coils are commonly used in various industries such as construction, automotive, and appliance manufacturing. They are used for roofing and siding applications, as well as for making durable and aesthetically pleasing metal doors, window frames, and garage doors. Additionally, pre-painted steel coils are utilized in the production of electrical enclosures, air conditioning systems, and various other metal components that require corrosion resistance and a visually appealing finish.
- Q: Why are properties of steel not identical?
- Steel is manufactured to different specs. To match the needs of its intended end use .Tensel strength,Hardness, Corosion resistance etc. The chemical make up will change to suit.
- 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: What are the commonly used molds steel?
- Usually a hot working grade ( H series ) tool steel is used in die cast mold detail tooling. We typically use H-13 for our applications but have substituted with D-2 on occasion.
- Q: What is the difference between hot-rolled and cold-rolled steel coils?
- The main difference between hot-rolled and cold-rolled steel coils lies in the production process. Hot-rolled steel coils are made by heating the steel above its recrystallization temperature, causing it to become malleable and allowing it to be rolled into the desired shape. This process results in a thicker and less precise product with a rough surface. On the other hand, cold-rolled steel coils are made by cooling the hot-rolled steel and then passing it through rollers at room temperature. This process enhances the steel's strength, durability, and dimensional accuracy, resulting in a thinner and smoother product that is ideal for applications requiring precision.
- Q: How do steel coils contribute to energy efficiency in lighting?
- The energy efficiency of lighting relies heavily on the type of light source chosen, such as incandescent, fluorescent, LED, or halogen bulbs. Each of these light sources consumes energy differently. On the other hand, steel coils serve a different purpose in lighting fixtures. Their main function is to provide structural support, dissipate heat, and protect the components. They do not have a direct impact on the energy efficiency of the lighting system. However, steel coils can indirectly improve energy efficiency by offering sturdy support to the fixtures. This ensures that the installations are reliable and long-lasting, reducing the need for frequent maintenance and replacements. A well-supported lighting system guarantees optimal performance and minimizes energy wastage or inefficiencies caused by loose or unstable fixtures. Furthermore, steel coils can also be used to manufacture reflectors or housings for lighting fixtures. These components play a role in enhancing the overall efficiency and distribution of light. By effectively reflecting and directing the light output, energy utilization and illumination can be optimized, resulting in reduced energy waste. Although steel coils themselves do not directly influence the energy efficiency of lighting, their incorporation in the construction and support of lighting fixtures indirectly contributes to a more energy-efficient lighting system.
