Q: I just bought a used Taurus 85 stainless 38 spl revolver, it's about 25 years old but looks like new. This is my first stainless steel gun. I'm wondering if there's any special things I need to be aware of or cleaning methods? I'm also wondering if stainless steel could rust? in theory stainless means it cannot get stained or rusty. I have a chrome bore AK, cleaning is always super easy, wondering of cleaning a SS revolver would be the same.: Q: will a stainless steel gun rust? A: Under certain conditions, it can rust. But stainless steel will last longer than blued steel will under such conditions. Also, some parts of a stainless steel revolver might not be stainless steel. The internal parts may be normal steel. Q: I just bought a used Taurus 85 stainless 38 spl revolver, it's about 25 years old but looks like new. This is my first stainless steel gun. I'm wondering if there's any special things I need to be aware of or cleaning methods? A: There are no special methods required. Stainless steel is fairly convenient easy to clean and maintain. Carbon-fouling can still build-up and metal discolorations may occur. These can be cleaned up with cleaning solvents and the use of a Scotch-brite cleaning pad or something similar. If it gets a scratch, the scratch can be polished away or left alone and the scratch can become a badge of honor or something. Q: I have a chrome bore AK, cleaning is always super easy, wondering of cleaning a SS revolver would be the same. A: Stainless steel is pretty tough on its own. Chrome-lining a stainless steel barrel wouldn't be considered cost effective in most circumstances. Cleaning the inside of a stainless steel barrel will be similar to cleaning a blued steel barrel that is not chrome-lined.

Q: Which steels were origianally designed to be used to cut and shape metals and other materials?- alloy steel- high carbon steel- carbide steel- tool steelthanks: Steels okorder

Q: How long can steel coils be stored before they need to be used?: Steel coils can typically be stored for an extended period of time, ranging from a few months to several years, depending on various factors such as the coating, storage conditions, and the type of steel. However, it is generally recommended to use or sell steel coils within a year or two to ensure their optimal quality and performance.

Q: How are steel coils inspected for oil or rust residues using chemical analysis?: Steel coils can be inspected for oil or rust residues using chemical analysis techniques. One of the commonly used methods is Fourier transform infrared spectroscopy (FTIR). In this technique, a small sample of the steel coil is taken and subjected to infrared radiation. The infrared spectrum obtained is then analyzed to identify the presence of specific chemical bonds that are characteristic of oil or rust residues. For detecting oil residues, a common approach is to use the peak at around 2920 cm-1 in the FTIR spectrum, which corresponds to the C-H stretching vibration in hydrocarbon chains. If this peak is observed, it indicates the presence of oil residues on the steel coil. To identify rust residues, the FTIR spectrum is analyzed for the presence of characteristic peaks corresponding to iron oxide or hydroxide compounds. For example, the presence of a peak at around 560 cm-1 suggests the presence of iron oxide (FeO) or iron hydroxide (Fe(OH)3). In addition to FTIR analysis, other chemical analysis techniques can also be utilized, such as X-ray fluorescence spectroscopy (XRF) or energy-dispersive X-ray spectroscopy (EDX). These techniques can provide elemental composition information, allowing for the identification of specific elements associated with oil or rust residues, such as carbon or iron. Overall, the chemical analysis of steel coils for oil or rust residues provides a reliable and accurate method to ensure the quality and cleanliness of the coils before further processing or usage.

Q: What are the common coil surface treatments?: The common coil surface treatments include galvanization, electroplating, painting, and powder coating.

Q: How are steel coils used in the production of steel beams?: Steel coils are used in the production of steel beams by being unwound and fed through a series of rollers and machines. These coils are transformed into flat sheets of steel, which are then cut and shaped to create the desired dimensions and specifications of steel beams.

Q: I know that mild steel is more brittle than cast iron....but that is all.......please help??Thank you in advance......Ruby:D: Actually, the opposite is true. CAST IRON is generally brittle, while mild steel is not. Cast iron has a carbon content from about 2%-4%. Mild steel has less than one tenth as much carbon as cast iron- around 0.2% - 0.3%. Cast iron also typically has from 1%-3% silicon. Most mild steel contains no more than 0.3% silicon. Steel melts at ~1450 degrees C. The addition of large amounts of carbon and silicon to C.I. lower the melting point to around 1200 C and make it more fluid than molten steel. Obviously this makes it easier to melt and to pour. The main advantage of cast iron is it's cheap to produce. It also has some desirable properties despite it's brittleness. For example it's easy to cut and carve with machine tools. It's also very heat resistant and excellent at absorbing vibration. For this reason C.I. was commonly used for engine blocks and exhaust manifolds in cars and trucks in the past, (Cast aluminum engine blocks are more common these days because Al is much lighter and conducts heat better.) Cast iron also rusts much more slowly than steel which is why it's still commonly used for pipes. C.I. pipes have been known to last 300 years.

Q: What are the various surface finishes available for steel coils?: Steel coils offer a range of surface finishes, each with its own properties and uses. Some commonly used finishes include: 1. Hot rolled: Steel is rolled at high temperatures, resulting in a rough surface. This finish is great for structural applications like construction materials and industrial machinery. 2. Cold rolled: Steel is rolled at room temperature, creating a smoother surface. It is commonly used in automotive and appliance manufacturing due to its superior finish and accuracy. 3. Galvanized: Steel is coated with zinc to protect against corrosion. Galvanized coils have a shiny appearance and are suitable for outdoor applications such as roofing and fences. 4. Electro-galvanized: Coated with a thinner layer of zinc through an electroplating process, these coils offer good corrosion resistance. They are commonly used in electrical appliances, automotive parts, and construction. 5. Pre-painted: Coated with paint or polymer film, pre-painted coils provide both corrosion protection and aesthetic appeal. They are extensively used in construction for roofing, cladding, and wall panels. 6. Stainless steel: Stainless steel coils have unique properties, including corrosion resistance, heat resistance, and chemical damage resistance. They are ideal for industries like food processing, medical equipment, and marine applications. These examples showcase the variety of surface finishes available for steel coils. The choice of finish depends on factors such as the intended use, desired appearance, and level of corrosion resistance required.

Q: How is steel different than iron?How many different kinds of steel are there?What type is the strongest?Which type is the weakest?: steel has carbon in it instead of just iron there are hundreds if not thousands of different kinds of steel for different applications strength depends on the definition. some have stronger tensile (pull) strength than others.

Q: Steel is strong in both tension and compression. Concrete is only strong in compression, and is very fragile in tension. Plus, concrete is heavy--a huge drawback in, say, a bridge deck. And its fairly expensive. And it hides the condition of the steel embedded within it. So what does it bring to the table? Why use it at all?: Exposed steel requires constant maintenance including inspection and repainting. Steel does not provide a durable driving surface nor a good friction one for stopping unless it is textured, which makes driving on it very noisy. It is not possible to refinish a steel surface as is a concrete surface which can be ground and had several inches of new wear surface in concrete or asphalt added to it. Concrete is much less expensive than steel and the enclosure of steel inside the concrete protects it like a paint job does. Steel is weakened by heat, as was shown by the 9/11 collapses when the applied fire insulation was blasted off the trusses by the crashes, so a burning truck on or under a bridge may damage concrete but leave it standing strong enough to continue handling traffic during repairs, as at overpasses here in Texas where oil tankers crashed and burned.
