Q: I was looking at my Great-Grandfather's immigration form from when he immigrated from Scotland and he listed his occupation as a steel dresser. What does a steel dresser do?: I'm not sure, but it could be like and engineer working in steel design or steel polisher. I checked Wikipedia and Yahoo but found nothing. It may be a description of something only in Scotland. Sorry

Q: Can't find it- this is for a physics experiment for youngs modulus done with a steel wire.: It depends on the type of steel and how the wire was made (e.g. whether it was drawn hot or cold, whether it was heat treated after it was drawn, etc). For mild steel the elastic limit is about 400 MPa. Note this is not the same as the breaking stress for the wire which will typically be significantly higher for a ductile material like steel. If you want to measure a stress-strain curve to find youngs modulus, make sure you measure several points at stresses below the elastic limit - for example try increasing the stress in increments of about 50 MPa.

Q: What are the different types of surface treatments for steel coils?: There are several different types of surface treatments available for steel coils, each designed to enhance the appearance, protect against corrosion, and improve the overall durability of the steel. Some of the commonly used surface treatments for steel coils include: 1. Hot-dip galvanizing: This process involves immersing the steel coils in a bath of molten zinc, which forms a protective layer on the surface. Hot-dip galvanizing provides excellent corrosion resistance and can withstand harsh environments. 2. Electro-galvanizing: In this method, a thin layer of zinc is electroplated onto the surface of the steel coils. Electro-galvanizing offers good corrosion resistance and improves the aesthetics of the steel. 3. Organic coating: Steel coils can be coated with organic materials such as paints, lacquers, or polymer films. These coatings provide protection against corrosion, abrasion, and UV radiation, while also offering a wide range of color options. 4. Phosphating: Phosphating is a chemical treatment that converts the steel surface into a layer of phosphate crystals. This treatment enhances the adhesion of subsequent coatings and improves the corrosion resistance of the steel. 5. Chromating: Also known as passivation, chromating involves the application of a chromate conversion coating onto the steel surface. This treatment enhances the corrosion resistance and provides a decorative finish. 6. Oiling: Oiling is a simple surface treatment that involves applying a thin layer of oil onto the steel coils. This treatment helps prevent corrosion during storage and transportation and can be easily removed before further processing. 7. Pickling: Pickling is a process where the steel coils are immersed in an acid solution to remove impurities and scale from the surface. This treatment improves the surface finish and prepares the steel for subsequent processing or coatings. 8. Tin plating: Steel coils can be coated with a layer of tin through electroplating. Tin plating provides excellent corrosion resistance, solderability, and aesthetic appeal. These are just a few of the many surface treatments available for steel coils. The choice of treatment depends on the specific requirements of the application, including the desired appearance, corrosion resistance, and environmental conditions the steel will be exposed to.

Q: Can steel coils be coated with scratch-resistant materials?: Yes, steel coils can be coated with scratch-resistant materials. These materials are designed to provide an additional layer of protection to the steel surface, minimizing the risk of scratches or damage during handling, transportation, or storage.

Q: How are steel coils inspected for surface finish variations?: Steel coils are inspected for surface finish variations by using techniques such as visual inspection, magnetic particle inspection, and surface roughness measurement.

Q: What are the different methods of laminating steel coils?: There are several different methods of laminating steel coils, each with its own advantages and applications. The most common methods include hot rolling, cold rolling, and continuous annealing. Hot rolling is a process in which steel is heated above its recrystallization temperature and then passed through a series of rollers to produce thin sheets or coils. This method is commonly used for producing large quantities of steel with a consistent thickness and surface finish. Hot rolled steel coils are often used in structural applications, such as construction and automotive manufacturing. Cold rolling, on the other hand, involves passing the steel coil through a series of rollers at room temperature. This process not only reduces the thickness of the steel but also improves its surface finish and mechanical properties. Cold rolled steel coils are typically used in industries that require high precision and quality, such as appliance manufacturing, electrical equipment, and automotive components. Continuous annealing is another method of laminating steel coils. It involves heating the steel coil to a specific temperature and then slowly cooling it in a controlled environment. This process helps to relieve internal stresses and improve the steel's mechanical properties, such as strength and ductility. Continuous annealing is often used for producing high-quality steel coils for applications that require superior surface finish and formability, such as automotive body panels and household appliances. Other less common methods of laminating steel coils include electro-galvanizing, which involves coating the steel with a layer of zinc through an electroplating process, and hot-dip galvanizing, where the steel coil is dipped into a bath of molten zinc. These methods are primarily used for corrosion protection and are commonly seen in the construction industry, particularly for outdoor structures and infrastructure. In summary, the different methods of laminating steel coils include hot rolling, cold rolling, continuous annealing, electro-galvanizing, and hot-dip galvanizing. Each method offers distinct benefits and is chosen based on the specific requirements of the application.

Q: How are steel coils used in the manufacturing of automotive doors?: Steel coils are used in the manufacturing of automotive doors by being shaped and cut into the desired size and shape for the door panels. These coils are then formed into the appropriate curvature and attached to the door frame, providing strength, rigidity, and durability to the door structure.

Q: I know that steel wool is coated with... something... that protects it from rusting. I need to know what that is, and how to get it off.: It will be very effective if you remove the oil by appling protective polymer spin coating to the edge, top and underside of the wafer, which makes those surfaces impervious to most chemical etchants. To learn more about the spin coating theory you may check out the following source.

Q: Why is it usually scorned by the shooting community to use steel cased ammo (like Wolf)? Always hear corrosive and steel is bad for the extractor/firing pin. Hulp a simpleton out!: I okorder /

Q: How do steel coils contribute to the construction equipment industry?: Steel coils are essential in the construction equipment industry as they are used to manufacture various components like beams, plates, and tubes. These coils provide the necessary strength and durability needed for constructing heavy machinery and equipment. Additionally, steel coils are also utilized in the fabrication of structural frameworks, reinforcing bars, and other critical parts, ensuring the integrity and safety of construction equipment.
