Q: Any details about JinSong Ferritic Stainless Steel?: The steel is added with Mo on the basis of 10Cr17 steel to improve its corrosive pitting resistance and crevice corrosion resistance; it has higher intensity and better salt solution corrosion resistance than 10Cr17 steel. The steel is mainly used in making automobile hub bearing, fastener and external decoration of automobile.

Q: what happened to all the steel beams from the WTC buildings? did anyone do any forensic analysisof any of the steel?: Some of the steel was recycled for sale to other countries where they aren't so picky about reusing building materials. NIST had 200 pieces of the steel for their investigation, which they returned last year. This was covered in the press. The rest of the steel was held at JFK international airport's Hangar 17. Much of it will be placed/has been placed in the new museum beneath the Memorial at the WTC site. Thousands of pieces are being given out for 9/11 memorials all over the world. Just about every day you read in the newspaper about another piece going here or there to this city or that city. Yes, a lot of the steel was tested for a number of chemical compounds. It had to be for safety reasons before storing it and giving it out. Depending upon what countries the recycled beams were sent to and their rules, it was sometimes tested at the ports of entry over there, as well.

Q: What are the typical lead times for ordering steel coils?: Lead times for ordering steel coils can vary based on factors such as coil type, size, supplier capacity, and market conditions. On average, lead times range from a few weeks to several months. When it comes to standard-sized steel coils readily available in the market, lead times are generally shorter. This is because suppliers keep stock of these commonly used sizes to meet immediate customer demands. However, transportation and logistics can still impact lead times. For custom-made or non-standard steel coils, lead times tend to be longer due to additional processes like cutting, shaping, or coating. Production time can range from a few months to six months or more, depending on the complexity of specifications and supplier capabilities. External factors like market demand and raw material availability can also affect lead times. During high demand or supply chain disruptions, suppliers may need to adjust production schedules, leading to extended lead times. To determine accurate lead times, it is recommended to contact specific suppliers or manufacturers. They can provide the most up-to-date information based on your requirements and current market conditions.

Q: i am looking for an exact process of how to forge damascus steel.any tips or pointers and web sites or tutoreals will be helpfull.: hand made folding knife English tip, blade of Damascus metallic sort Rose, 2,5mm thickness, no liners, teja spring embellished by using metallic report and billet surrounded of chrome metallic. A Damascus blade knife is characterised by using a wavy, mottled visual allure on the blade that’s led to by using the approach used to shape the metallic. the technique of transforming into Damascus metallic is derived from a centuries-previous forging technique used to create blades that grew to become very just about mythical of their attractiveness for power and sharpness it exchange into reported a Damascus knife ought to shrink with the aid of a rifle barrel to boot as with the aid of a hair falling on the blade.

Q: What are the different methods of coil recoiling for steel coils?: Steel coils can undergo coil recoiling using various methods, each with its own advantages and applications. Some commonly used methods include: 1. Slitting and rewinding: This method entails cutting the wide steel coil into narrower strips, which are then rewound into smaller coils. Circular blade slitting machines are typically employed for steel cutting, while the rewinding process ensures tight and uniform winding of the narrower strips. Industries like automotive, construction, and packaging widely employ this method. 2. Rewinding with tension control: This method involves unwinding and rewinding the steel coil using tension control systems. These systems maintain consistent tension throughout the recoiling process, resulting in uniform winding quality. This method proves beneficial when handling delicate or sensitive materials that require gentle treatment. 3. Recoiling with edge trimming: In situations where steel coil edges are damaged, uneven, or flawed, edge trimming can be combined with the recoiling process. Edge trimming machines remove defective sections, ensuring coils with smooth and even edges. 4. Recoiling with surface treatment: Steel coils often undergo surface treatment processes like oiling, coating, or galvanizing to enhance corrosion resistance or improve surface properties. Recoiling can be performed alongside these treatments, guaranteeing proper application and uniform coverage across the entire coil surface. 5. Recoiling with tension leveling: Tension leveling is a process that eliminates coil shape defects, such as coil set or crossbow, by applying tension during recoiling. This method ensures a flat and even coil shape, which is advantageous for subsequent processing and manufacturing operations. 6. Recoiling with precision slitting: Precision slitting is a specialized method used to achieve extremely narrow strip widths or tight tolerances in the steel coil. It involves precise control of slitting knives and winding tension to ensure accurate and consistent strip dimensions. Industries requiring high precision, such as electronics or precision engineering, commonly employ this method. In summary, the choice of coil recoiling method depends on factors such as desired coil dimensions, material characteristics, surface requirements, and the specific industry or application. Manufacturers often combine multiple methods to meet the diverse needs of their customers.

Q: How does stainless steel soap work? I have read the detailed explanation on Wikipedia, but their desciption seems skeptical on the actual chemical process that may take place from using such an item. Is there an actual scientific explanation to how stainless steel soap is able to clean your hands, when it is only a piece of metal?: Many metals have germicidal qualities. Silver is the strongest germicide of the metals, but a sterling silver bar of soap would be expensive and it would tarnish. The tarnish would actually not affect the silver's ability to kill bacteria, but it would look bad and the tarnish would turn your hands black, so people wouldn't want to use it. Many people even take silver internally in the form of Colloidal Silver, but Colloidal Silver is very controversial. Yes, it kills many bacteria, but it can also cause a person's skin to permanently turn blue...a condition called Argyria. Brass actually is a better germicide than stainless steel...but again this is a cosmetic problem. Brass tarnishes, so people wouldn't want to use it. Stainless steel is actually a very weak germicide, but even steel has some ability to kill germs. Stainless steel also removes fish odor. My son has a stainless steel bar that he takes along when he fishes to remove the fish smell from his hands. There's nothing magical about the bar...a stainless steel spatula would would just as well, but the bar is more convenient to carry. I'm not sure if this is scientific enough or not. -

Q: Can steel coils be coated with aluminum?: Yes, steel coils can be coated with aluminum through a process called coil coating.

Q: what do they use to make stainless steel?and can stainless steel be melted again and again without losing it's Specifications: The basic ingredient is from 11%-30% chromium, however in many stainless steels nickel or manganese are important secondary ingredients. There are two basic types of stainless steels: 1)austenitic stainless steels, and 2)ferritic stainless steels. In austenitic SS the important ingredients are Chromium and Nickel. (Chromium and manganese are occasionally use instead of nickel.) It's important to note that many austenitic SS's contain almost no carbon, so by some definitions they are not steel at all but iron/chromium/nickel alloys. the additions of nickel (or manganese) actually changes the crystal structure of the iron, so the properties of these types are quite different from normal carbon steels. Austenitic SS have very good to excellent corrosion resistance, and fairly good heat resistance. In ferritic stainless steels, the important ingredients are chromium and carbon. Ferritic stainless steels have markedly greater strength than austentitic types. However since they contain less chromium than austenitic types they are only moderately corrosion resistant and are much less heat resistant. Without the addition of nickel and/or manganeese adding more than about 20% chromium tends to make the steel brittle. Most stainless steel is melted under an inert argon atmosphere in an airtight furnace. Melting stainless in open air would preferentially oxidize the chromium, forming slag which would float to the surface of the steel, thus reducing the chromium content. Chromium also tends to react with nitrogen in the air at high temperatures, exposure to nitrogen tends to cause brittleness in stainless steels. As long as the manufacturer keeps careful control of the composition of the metal and the level of impurities during melting, stainless is endlessly recyclable.

Q: So I was thinking about doing corset waist training and I wanted to know where I can get a real steel boned corset?: Hi, okorder / There are 3 types of corsets: Fashion corsets, Authentic corsets and Waist training corsets. The fashion corsets are designed for light enclasping of body. They are made with plastics bones usually. The authentic corsets can reduce your waist size about 4 - 5 and the waist training corsets about 6. They both are made with steel spirals and flat bones. The waist training corsets are recommended for experienced wearers only. Look on info pages of the seller. The corsets reinforced with plastic bones are cheap with low durability.

Q: What are the disadvantages of using steel coils?: One disadvantage of using steel coils is their high weight and bulkiness, which can make transportation and handling more difficult and costly. Additionally, steel coils are prone to rust and corrosion, requiring proper maintenance and protective coatings to prevent deterioration. Lastly, steel coils can be expensive to produce and purchase, making them less cost-effective compared to alternative materials in certain applications.
