Q:explain what happen if carbon steel is exposed to an oxygen rich atmosphere at elevated temperature inside a furnace.: Blowing oxygen or air rich in oxygen through molten carbon steel is a way of lowering the carbon content. The properties of carbon steel depend very much on the carbon content . too much and it is very brittle. It is all governed by a complex phase diagram. If the steel isn't actually melted, then only insignificant effects at the surface will occur.

Q:What are the different types of steel processing equipment for coils?: There are several types of steel processing equipment used for coils, including slitting lines, cut-to-length lines, blanking lines, and coil-to-coil lines. Slitting lines are used to slit wide steel coils into narrower strips, while cut-to-length lines are used to cut coils into specific lengths. Blanking lines are used to cut shapes out of coils, and coil-to-coil lines are used to transfer coils from one processing stage to another.

Q:Does SA use its own iron ore to produce steel for construction or do we rely on imports?: SA got its own steel and iron production going that is one of our main exports They don't make Rail's for railway line any more we in port it

Q:My musical saw has, despite my best efforts, got little patches of rust on it. How Do I go about removing the rust without spending too much on rust-removal products and without affecting the properties of the steel?: Steel wool and a bit of WD 40. Steel wool will remove the rust and the WD 40 will protect it in the future.

Q:Can anyone tell me what that means. I have seen it on knife blades an such. I am assuming it's a formula for the strength of the metal. who does that scale work, and please keep it simple.: The number just indicates which class of steel alloy it belongs. Yours happens to be a 400 series and happens to have no Nickel in it (440 Steel) and a higher amount of carbon (Nickel is very common in steel) When I say alloy, I'm referring to the different chemical formulas and processing of steel which vary for different uses like industrial use, medical use or decorative use. Think of the different alloys like the types of soft drinks out there. Coke, Pepsi and Dr. Pepper. They all have very similar chemical formulas; yet differ with their secret ingredients which is apparent in the taste.

Q:How are steel coils processed for edge trimming or shearing?: Steel coils are processed for edge trimming or shearing by first uncoiling the coil and feeding it into a machine equipped with either rotary shears or slitting knives. These tools trim or shear the edges of the coil to remove any irregularities, ensuring a precise and uniform width. The trimmed edges are then inspected for quality and smoothness before the coil is recoiled for further processing or storage.

Q:I've heard on some 1911 forums that the slides of Armscor guns are now extruded. What is extruded steel? How is it made? Are they strong (4140carbon steel was used in the process).: Extruded steel is only the steel being run through a die when it is heated, it usually reduces the size of the grain of the steel itself, enhancing toughness. Realistically though, in a handgun, it doesn't matter if the frame is cast or forged, both types will hold up to any amount of abuse, unless you use it as a sledgehammer, and are splitting stones with it, then the forged frame would win. 4140 is more than adequate for a slide/frame. Hell, even mild steel would be adequate as long as you don't mind some dings and scratches, and again, don't use it as a sledgehammer...

Q:I work in a steel foundry 10-12 hours a day where we melt and pour stainless steel tubes. The pour temperature for some of them is very close to the boiling point of stainless steel (about 3800 degrees) because it has to be VERY liquid for the application we use it. Anyway, it does boil a little and we breath in the vapours which I can assure you ARE indeed vapourized stainless steel (it collects and cools on everything and makes a nice shiny coating). Ok, so to the question, does breathing vapourized stainless steel all day pose a health risk such as cancer? Anyone know? I'm just curious.: you okorder

Q:The strip tower height: Causes: the strip has a larger snake shape; the take-up device holds the tension; the setting is unreasonable; the strip goes into the coiler; the centering is not good; the coil tension is not set properly.

Q:How does the surface finish of steel coils affect their performance?: The surface finish of steel coils significantly affects their performance. A smooth and even surface finish enhances the coil's ability to resist corrosion, improves paint adhesion, and enhances the overall appearance of the final product. Additionally, a properly finished surface reduces friction, facilitating better processing and handling during manufacturing. Therefore, the surface finish of steel coils plays a crucial role in determining their durability, functionality, and aesthetic appeal.
