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: If needed for Defence could a stainless steel sword kill someone my buddy wanted this sword for Defece after it is sharpend here is a picture: Ya it could kill someone if it was sharpened enough but from experience stainless steel swords don't get as sharp as Carbon or higher grade steel. Not to mention it would probably bend if you hit someone with it all the way. Hell the one I let some people who were chopping a bush ( just a normal bush ) they were playing around and it got bent. I'm going to say I can't suggest a stainless steel sword for anything other then handing on your wall. Not even going into the whole If you use a sword for self defense is it considered self defense? debate. It's a sketchy situation not to mention you would need training with a sword to actually use it without it just getting brushed off.

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 factors that affect the price of steel coils?: There are several factors that influence the price of steel coils. Firstly, the cost of raw materials such as iron ore and coal, which are essential for steel production, can significantly impact the price. Additionally, the demand and supply dynamics of steel in the market play a crucial role. Factors like economic growth, construction activity, and infrastructure development can drive up the demand for steel, leading to price increases. On the other hand, if there is excess supply or reduced demand, prices may decrease. Moreover, fluctuations in energy costs, transportation expenses, and currency exchange rates can also affect the final price of steel coils.

Q: I also heard Stainless holds up better againts rust, blue steel needs more care.: Stainless steel requires less maintenance, but I've got a K-38 Combat Masterpiece from 1974. Back then SW used the real blueing process, and the blue steel looks like its a foot deep. Probably the best looking gun in the accumulation. Still new in the box, never fired. Its my Vietnam tribute gun, same one I carried as a Security Policeman in the Air Force from 1969-1971.

Q: How are steel coils used in the manufacturing of suspension arms?: Steel coils are used in the manufacturing of suspension arms as they provide strength and flexibility to absorb shocks and vibrations. These coils, also known as coil springs, are compressed and installed in the suspension system to support the weight of the vehicle and maintain proper ride height. The use of steel coils allows for better handling, stability, and improved overall performance of the suspension arms.

Q: I was watching a documentary on the samurai vs the European knight. It said that the when Japan was being invaded by the (cant remember) they needed a new weapon. The enemies armor made iron swords useless. While steel swords broke when in combat. So to combat this the Japanese made a hybrid sword. They used a special mold that made the swords back iron while the part that makes contact with the enemy was steel. Also the sword was curved so it increased its armor and cutting power. This revolutionary design made the the sword stronger. The iron back made it not break while the steel edge made it cut through the enemies armor. I want to know how iron is stronger than steel, and how steel can cut better than iron.: This Site Might Help You. RE: Why is iron stronger than steel?

Q: What are the different methods of coil packaging for steel coils?: Steel coils can be packaged using various methods, each with its own advantages and suitability for specific applications. Some commonly used methods include: 1. Strapping: Steel or plastic strapping is used to secure the coil and prevent unwinding or shifting during transportation. Strapping can be done manually or with strapping machines, providing a reliable and cost-effective packaging solution. 2. Stretch wrapping: This method involves tightly wrapping the coil with a stretch film. The film is stretched and wrapped around the coil, offering protection against dust, moisture, and damage. Stretch wrapping is suitable for lightweight coils and provides good visibility of the product. 3. Steel banding: This robust and heavy-duty method uses steel bands to secure the coil. It ensures high strength and durability, keeping the coil intact during transportation or storage. 4. Edge protectors: To safeguard the edges of the coil, edge protectors made of cardboard or plastic are used in combination with other packaging methods. These protectors provide additional support to prevent edge damage. 5. Wooden crates: For heavy or fragile steel coils, wooden crates are often used to provide maximum protection. The coils are placed inside the crate and secured with strapping or steel banding. Wooden crates offer excellent strength, stability, and can be customized to fit specific coil dimensions. 6. Paper interleaving: This method involves inserting layers of paper or cardboard between individual wraps of the coil to prevent scratching or marking. Paper interleaving is commonly used when stacking coils or when protecting a high surface finish. 7. Automated packaging systems: In larger-scale operations, automated packaging systems can be used. These systems are designed to handle and package coils using various methods such as strapping, stretch wrapping, or steel banding. They ensure increased efficiency, productivity, and consistent and secure packaging. The choice of coil packaging method depends on factors including coil size and weight, transportation requirements, required level of protection, and cost considerations. It is crucial to select the appropriate packaging method to ensure the safe delivery of steel coils to their destination.

Q: Hi can someone help me pleaseis there any available data for mechanical behaviour of recycled steel, i need to compare them with new steel.: Most recycled steel is blended with new steel at the steel mill. Scrap steel that is reused directly doesn't change it properties because it has been used. That is unless it has been in certain environments such as ones with hydrogen, hydrogen sulfide etc. Then the steel can become brittle. You might look for information on the National Association of Corrosion Engineers (NACE). They have lots of information on metals and what causes problems.
