- Q: Ok, lately I've been taking to making things out of stainless steel chain mallie rings. The problem is that when i make a bracelet or something, the area around the fastener always looks pretty bad. I'm thinking to have a friend who also does chain mallie finish the weave all the way around. This would make it look good but make it impossible to remove.Are there any long term problems with stainless steel on skin? I know some metals will change the color of the skin or make the skin absorb some of the metal. Is this something to worry about with stainless steel?
- Stainless steel contains both nickel and chromium. These two alloys are responsible for most of contact dermatitis in people. Some of my co-workers making steel had such bad reactions to chromium that they had to quit their jobs. Their skin was always inflamed. People don't react to finished stainless steel the same way because the alloys are bonded tightly in the heat treating process. But if you are grinding it and getting the dust on your skin, you could get a contact dermatitis if you are sensitive. I don't think it would absorb into your blood stream or do any long term damage to your skin. If you do get a reaction, you would have to cease your exposure or in a worse case scenario risk getting a body wide reaction like my coworkers. I would not worry about any exposure making rings out of stainless steel. After all, stainless steel is used in sugical implants and most people are fine.
- Q: What is the thickness of a steel coil?
- The thickness of a steel coil can vary depending on the specific requirements and application. Typically, the thickness of a steel coil can range from a few millimeters to several centimeters.
- 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: What are the different methods of perforating steel coils?
- Various techniques are employed to perforate steel coils, each possessing unique merits and applications. 1.

- Q: How are steel coils processed before being used in manufacturing?
- Steel coils undergo several processing steps before they are used in manufacturing. The first step is to uncoil the steel coil, which involves unwinding it from a large spool. This is usually done using a machine called a decoiler. Once the coil is uncoiled, it is inspected for any defects or damages. After inspection, the steel coil goes through a process called leveling. This process involves passing the coil through a series of rollers to remove any unevenness or waviness in the steel. Leveling ensures that the coil has a uniform thickness and flat surface, which is crucial for further processing. The next step is to clean the steel coil to remove any impurities, such as rust, oil, or dirt. This is usually done by running the coil through a cleaning line, where it is treated with chemicals and water sprays. The cleaning process ensures that the surface of the coil is free from contaminants, which can affect the quality of the final product. Once the coil is cleaned, it may undergo additional processes depending on the specific requirements of the manufacturing process. For example, the coil may be annealed to improve its ductility and reduce its hardness. Annealing involves heating the coil to a specific temperature and then slowly cooling it. This process helps to relieve internal stresses and improve the steel's mechanical properties. After all the necessary processing steps are completed, the steel coil is ready to be used in manufacturing. It can be further processed into various shapes and forms, such as sheets, plates, or strips, depending on the specific requirements of the manufacturing process. These processed steel coils are then used in a wide range of industries, including automotive, construction, appliances, and machinery.
