- Q: Could someone please explain what happens when steel is heat treated and why these happenings cause the steel to become harder? Please dig down into the micro details of the crystallites but in somewhat laymen's terms. Also describe the processes which achieve these results; if you have the time. Thanks for your time and effort.
- Mild steel is a solution of carbon within iron, etc. When the steel is very hot the carbon is well distributed. As the steel is cooled iron crystals form excluding the carbon that will then collect at the boundaries (grain boundaries) between iron crystals. If cooling is rapid at any point in the cool down crystal growth will cease (affecting final grain size and the mix of carbon and iron at the grain boundaries). The ductility or hardness of the resulting steel will be determined by the grain sizes and makeup of the carbon/iron mix between grains. Ductile iron permits 'slabs' of iron to slip past each other within iron crystals and location of carbon atoms may help prevent slip resulting in hardness. Therefore, heat treatment usually consists of 'soaking' the steel at a temperature high enough to dissolve all the carbon uniformly then cooling it down slowly or rapidly to obtain optimum grain size and interstitial carbon between grains to obtain desired properties.
- Q: How are steel coils processed for pickling or oiling?
- Steel coils are processed for pickling or oiling through a series of steps. First, the coils are unwound and cleaned to remove any dirt or debris. Then, they are passed through an acid bath to remove any oxides or rust from the surface of the steel. After pickling, the coils are rinsed with water to neutralize the acid. Finally, the coils may undergo an oiling process where a thin layer of oil is applied to protect the steel from corrosion.
- Q: What are the common coil lengths available for steel coils?
- The steel coil lengths offered in the industry and specific requirements are subject to variation. Nonetheless, several standard coil lengths are extensively employed in different applications. These encompass coil lengths of 100 feet (30.48 meters), 200 feet (60.96 meters), 300 feet (91.44 meters), and 500 feet (152.4 meters). These lengths find extensive use in construction, manufacturing, and automotive sectors, where steel coils serve diverse purposes. It is worth mentioning that coil lengths can also be tailored to meet specific project requirements or customer preferences.
- Q: How are steel coils used in the production of metal storage systems?
- Steel coils are typically used as a primary raw material in the production of metal storage systems. These coils are unrolled and processed through various machines and equipment to form different components such as shelves, frames, and supports. The steel coils are cut, shaped, welded, and coated to ensure durability and strength. Additionally, the coils can also be used to create interlocking panels or sheets that form the walls and roofs of the storage systems. Overall, steel coils play a crucial role in the manufacturing process, providing the necessary material for the construction and assembly of metal storage systems.
- Q: How are steel coils inspected for yield strength?
- Yield strength inspection of steel coils involves a series of testing methods. The most commonly used method is the tensile test, where a small sample is taken from the coil and subjected to a controlled load until it reaches its yield point. In the tensile test, the sample is progressively stretched until it deforms and ultimately fractures. Throughout this process, the load and elongation data are continuously recorded. The yield strength is then determined by pinpointing the point on the stress-strain curve where the material starts showing plastic deformation or permanent elongation. Another approach to inspecting steel coils for yield strength is the hardness test. Since hardness is often linked to yield strength, a hardness test can estimate the material's yield strength. This test involves measuring the steel coil's surface resistance to indentation or penetration using instruments like a Rockwell or Brinell hardness tester. Moreover, non-destructive testing methods like ultrasonic testing and magnetic particle inspection can also be utilized to assess yield strength. Ultrasonic testing employs high-frequency sound waves to detect any internal defects or inconsistencies in the material's structure. On the other hand, magnetic particle inspection relies on the application of magnetic fields and the usage of magnetic particles to identify surface cracks or defects. In conclusion, there are various testing methods available to inspect steel coils for yield strength. These methods offer valuable information to manufacturers and inspectors regarding the steel's quality and performance capabilities, ensuring that it meets the required standards and specifications.
