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 are the different coil edge options?

The different coil edge options include open coil, pocket coil, continuous coil, offset coil, and Bonnell coil.

Q:I want to make a lap steel guitar in my wood tech class. can anyone give me a link to a video or site that has steps on how to build one.

Steel guitars have cables attached to foot pedals to change the sound. I don't know how this would work with the top resting on your lap.

Q:What are the different methods of embossing steel coils?

There are numerous techniques for embossing steel coils, each possessing unique characteristics and applications. Some of the most prevalent techniques include: 1. Hot embossing: By heating the steel coil to a high temperature and pressing it between two engraved rollers, this method allows for intricate designs or textures to be imprinted onto the surface. The heat softens the steel, facilitating the desired pattern transfer. 2. Cold embossing: In contrast to hot embossing, cold embossing does not require heating the steel coil. Instead, it employs pressure and specifically designed dies or stamps to produce the desired pattern. Cold embossing is commonly used for simpler designs or when working with heat-sensitive materials. 3. Roller embossing: This technique involves using a series of rollers with engraved patterns to imprint the design onto the steel coil. The coil is passed through the rollers, and the applied pressure transfers the pattern onto the surface. Roller embossing is often utilized for larger-scale production, delivering consistent and uniform results. 4. Laser embossing: A modern method that employs laser technology to create patterns on steel coils. The laser beam selectively melts or vaporizes the metal, generating the desired design. Laser embossing offers high precision and flexibility, making it suitable for intricate and detailed patterns. 5. Press embossing: This technique utilizes a press machine equipped with custom-made dies to imprint the desired pattern onto the steel coil. The coil is positioned between the dies, and the press machine applies pressure, transferring the pattern onto the surface. Press embossing is commonly used for large-scale production, achieving high-speed and high-volume embossing. Ultimately, the choice of embossing method depends on various factors, including design complexity, production volume, material properties, and cost considerations. Each technique possesses advantages and limitations, necessitating careful selection by manufacturers based on their specific requirements.

Q:So...that means Wolverine can stab him, right? Because Adamantite is stronger than steel. Correct?

Adamanium might be able to penatrate Superman's skin, but you would need a lot more force than Wolverine's arm could manage, perhaps an ultimate fastball special, fans know what I mean. It has never been determined what can penetrate Superman. Guess it depends on who's writing it.

Q:Can steel coils be used in the production of HVAC systems?

Yes, steel coils can be used in the production of HVAC (heating, ventilation, and air conditioning) systems. Steel coils are commonly used in the manufacturing of HVAC equipment such as air handlers, condenser coils, evaporator coils, and heat exchangers. Steel coils provide durability and strength, making them suitable for withstanding the high pressures and temperatures involved in HVAC operations. Additionally, steel coils offer good heat transfer properties, allowing for efficient heat exchange between the refrigerant and the air being conditioned. Overall, steel coils are a reliable and commonly used component in the production of HVAC systems.

Q:What are the different types of steel coatings for coils?

Coils can be coated with various types of steel coatings, each with its own unique properties and advantages. Some of the most commonly used coatings include: 1. Galvanized Coating: This type of steel coating is widely utilized for coils. It involves applying a layer of zinc to the steel, which provides excellent protection against rust and corrosion. It is particularly suitable for outdoor applications or environments with high moisture levels. 2. Galvannealed Coating: Galvannealed steel coating involves subjecting the galvanized steel to additional heat treatment, resulting in a matte finish and improved adhesion for paint. It offers enhanced corrosion resistance and is often preferred in the automotive and construction sectors. 3. Aluminized Coating: Coating steel coils with aluminum provides outstanding heat resistance and corrosion protection. Aluminized steel is commonly employed in exhaust systems and other applications involving high temperatures. 4. Organic Coatings: Steel coils can also be coated with organic materials like paints or powder coatings. These coatings offer additional protection against corrosion and can be customized to meet specific aesthetic requirements, available in a wide range of colors. 5. Tin Coating: Tin-plated steel coils are covered with a layer of tin, which provides excellent solderability and resistance to corrosion. This type of coating is frequently used in the production of cans and other food packaging materials. 6. Phosphate Coating: Phosphate coatings are often applied as a pre-treatment before other coatings to enhance adhesion and corrosion resistance. They create a thin, crystalline layer on the steel surface, facilitating better adhesion of paint or powder coatings. These examples illustrate the diversity of steel coatings available for coils. The choice of coating depends on specific application requirements, considering factors such as corrosion resistance, heat resistance, paint adhesion, and aesthetic preferences.

Q:How are steel coils used in the production of steel doors?

Steel coils are used in the production of steel doors as they provide the raw material required for the door manufacturing process. These coils are unwound and then cut into specific lengths to form the door panels. The steel coils are further processed through various steps, such as rolling, pressing, and shaping, to give the door its desired structure and design. Thus, steel coils serve as the foundation for creating sturdy and durable steel doors.

Q:could anybody tell me the the weight of a cubic metre of mild steel? and where to get this info from?

The density of mild steel is about 7.8 gm/cc. 1 cubic metre is 1,000,000 cc, so it weighs 7,800Kg - 7.7 tons.

Q:How are steel coils coated for added protection?

Steel coils are coated for added protection through a process called coil coating. During this process, the steel coils are cleaned and treated with a primer to promote adhesion. Then, a topcoat is applied, which can be a variety of materials such as paint, polymer, or zinc-based coatings. This coating provides a protective barrier against corrosion, abrasion, and other environmental factors, enhancing the durability and lifespan of the steel coils.
