Q:I bought a stainless steel water bottle today. I really like it, but there is no drinking spout, it just has a lid that screws on and off, and an open hole to fill it and drink out of. Is this normal for these bottles? Or do they usually come with a spout to drink from? I don't want to look like an idiot at the gym drinking from this cool bottle with no spout if there's supposed to be one! haha.

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

There are various types of coatings that can be applied to steel coils, each with its own specific purpose and benefits. 1. Galvanized Coating: This is one of the most common types of coatings applied to steel coils. It involves the application of a layer of zinc to the steel surface. Galvanized coatings provide excellent corrosion resistance, making them suitable for outdoor applications where the steel may be exposed to moisture or harsh environmental conditions. 2. Galvalume Coating: Similar to galvanized coating, galvalume coating also involves the application of a layer of zinc to the steel surface. However, it also includes a small amount of aluminum, which enhances the corrosion resistance and provides better heat reflectivity. Galvalume coatings are often used in roofing and cladding applications. 3. Pre-painted Coating: Pre-painted coatings involve the application of a layer of paint or primer to the steel surface. This type of coating allows for customization in terms of color and finish. Pre-painted coatings not only enhance the aesthetics of the steel but also provide additional protection against corrosion and weathering. 4. Organic Coating: Organic coatings are typically applied as a topcoat over a galvanized or galvalume coating. They are made of various resins, such as polyester, epoxy, or polyurethane, which provide additional protection against corrosion, abrasion, and chemicals. Organic coatings are commonly used in applications where both aesthetics and durability are important, such as in the automotive industry. 5. Metallic Coating: Metallic coatings, such as aluminum or zinc, are applied to steel coils using a process called hot-dip coating. These coatings provide excellent corrosion resistance and are commonly used in applications where the steel is exposed to high temperatures or corrosive environments. 6. Chromate Conversion Coating: Chromate conversion coatings are applied to steel coils primarily for their corrosion resistance properties. They are commonly used in electrical applications to protect against galvanic corrosion and improve conductivity. Overall, the type of coating applied to steel coils depends on the specific requirements of the application, including the desired level of corrosion resistance, aesthetics, and environmental factors.

Q:What really is the difference between stain-less steel and iron? I only know that iron is an element, and stain-less steel is an alloy...but what else is there?

Steel is an alloy composed of mainly iron and carbon. Pure iron is very rarely used anymore. Depend on the concentration of the carbon, you can get from wrought iron to high grade steel. For stainless steel, Chromium is added to the alloy to prevent rusting. Just go to wiki. you should be able to find a lot more about it

Q:I have been thinking of buying a knife that says it has damascus steel. The reason for the question is that many people told me that damascus steel does not exist anymore, and that damascus nowadays is fake. Is this true???

damascus steel it says is made from ore containing either tungsten or vanadium, although most tools I've seen are made from chrome vanadium, it wouldn't be hard in this day and age to get the proper material. Although it DOES say in wikipedia that apparently the technique died out a long time ago due to shortage of the ore. Then it talks about reproduction attempts. So theoretically, yes, it could be the deal deal. But it does refer at the bottom about damascend steel which is made with a different technique, you could be buying one of those. NEXT TIME JUST LOOK UP THE ARTICLE YOURSELF AND READ IT

Q:I need new sprockets on my GSX-R1, I've heard that alumnium sprockets wear out twice as fast as steel and the difference is not noticable

I would stick with what was on the bike steal front/rear and same chain size. I'm not crazy about changing the gearing, but it's definately important to stick to the stock stuff. steal lasts longer and a stock size chain is likely to last longer. I got 25.5k miles out of my stock chain/sprockets on my RC51. I went with stock gearing vortex steel front and JT steel rear and the top 530 EK chain. I expect that I will get another 25k miles before the set is changed again. I'm so used to the tall first gear, and don't need quicker accelleration. I also don't want to mess up the displayed road speed and recorded miles.

Q:Edward Humphrey wants to know... Can I use steel roofing on an older house?

We are having a metal roof installed on our rental property. We were told by a number of contractors that metal roofing is comparable in price to an asphalt roof. It is all a matter of personal preference. Metal roofing will last for upwards of 50 years, where an asphalt roof, if good quality, will last about 30 years. I personally believe that some house styles just would not look proper or authentic with a metal roof. Hope this helps.

Q:I'm doing a project on stainless steel dining utensils and its a little more difficult than i thought it would be. There are no sites on the web that tells the creator or when it was first used. There's no sites that that i can see of that talk about the history of stainless steel dining utensils, only dining utensils in general. Please help, i can't change my project now ):

The booklet 100 years of WMF (WMF: Württembergische Metallwarenfabrik / Wurttemberg Metal Ware Factory) includes the patent application (or better: trade mark application) for stainless Cromargan Steel for the production of cutlery in 1926. Cromargan was the company's fantasy name for stainless Krupp V2A steel. Page 86 (unfortunately WMF is a German company, the booklet therefore is in German). Has nice pictures anyways. Appendix: I found the text (a bit cut however) in English language (without images and booklet, just HTML). See below.

Q:What are the different types of welding methods used for steel coils?

There are several different types of welding methods commonly used for steel coils, including spot welding, seam welding, and flash butt welding. Spot welding involves applying heat and pressure to two overlapping pieces of metal to create a strong bond. Seam welding is similar to spot welding but is used for continuous welds along the length of the coil. Flash butt welding involves using an electric current to create a heat source between two ends of the coil, which are then pressed together to form a solid weld. These methods allow for efficient and effective joining of steel coils in various industrial applications.

Q:I am currently writing a manuscript, and would like to know whether guns made out of steel, burn or melt when exposed to flames. Thanks.

Steel melts around 2500°F (1370°C). That's hotter than most normal fires (obviously, your steel pots don't melt on the stove, do they?) but a blowtorch or something like that could do it.

Q:How are steel coils inspected for flatness variations?

Steel coils are inspected for flatness variations using various methods such as visual inspection, measurement techniques, and automated systems. Visual inspection involves trained personnel visually inspecting the coil's surface for any irregularities or deviations from flatness. Measurement techniques involve using precision instruments such as straight edges, feeler gauges, or laser sensors to measure the flatness at different points along the coil's length. Automated systems use advanced technologies like laser scanning or optical sensors to quickly and accurately detect any flatness variations in the steel coils. These inspections help ensure that the coils meet the required flatness specifications and quality standards.
