Q: What are the common sizes of steel coils used in the industry?: The common sizes of steel coils used in the industry vary depending on the specific application and requirements. However, some standard sizes include 36-inch, 48-inch, and 60-inch widths, with thicknesses ranging from 0.014 inches to 0.125 inches. Ultimately, the size of the steel coil is determined by factors such as the intended use, manufacturing process, and transportation considerations.

Q: explain what happen if carbon steel is exposed to an oxygen rich atmosphere at elevated temperature inside a furnace.: Assuming the steel isn't actually melted, two things will happen. First, a layer of iron(ii) oxide, FeO will slowly develop on the surface, getting thicker over time. This layer is usually poorly bonded to the metal surface, it tends to flake off, exposing fresh metal. This is known as mill scale, it's also known as wustite which is the mineral term. Second, the surface of the steel will become decarburized, essentially becoming pure iron, not steel. The depth of the decarburized layer depends on the temperature, time, and the diffusivity of carbon in the steel at the given temp. This has some implications to engineering, in hot-rolling or forging of steel shapes for example. It's often the case that the stress and strain in a material is greatest at or near the surface. Therefore the weakened, decarburized layer at the surface may have a much greater detrimental effect on the steel's performance than might be expected. In a more specific example, die and tool steels depend on their carbon content for their strength and wear resistance, Therefore if such steels are heated in an oxidzing atmosphere, wear resistance is totally destroyed: The thin decarburized iron layer will be extremely soft and malleable.

Q: I am doing a project on how revolvers work and what materials they use and would like to know what specific grade of stainless steel they use for the manufacturing of the frame and cylinder?: *Rifle barrels are usually made from steel alloys called ordinance steel, nickel steel, chrome-molybdenum steel, or stainless steel, depending upon the requirements of the cartridge for which they are chambered. The higher the pressure and velocity of a cartridge (pressure and velocity usually go up together), the faster it will wear out a barrel. To give a satisfactory service life, barrels for high velocity cartridges must me made from tougher and harder steel than barrels for lower pressure cartridges. *The 400 (416) series SS commonly known as ordnance grade , is what barrels are made from . *If you want your barrel to be made from super alloy then it is 718 Inconel ,but a costly affair.

Q: I work with stainless steel a lot and I know it's rust resistant but it's definitly not STAIN resistant. You might be able to remove some stains easier from it than you can from some other surfaces but when it does stain, its hard as heck to clean it. It takes forever to scrub stains off my stainless steel pans so maybe it should just be called rustless steel?: This okorder /

Q: What is the cost of steel coils?: The cost of steel coils can vary depending on factors such as the type of steel, quality, quantity, and market conditions. It is best to contact suppliers or check market prices for the most accurate and up-to-date cost information.

Q: How are steel coils inspected for yield strength using tensile testing?: Steel coils are inspected for yield strength using a testing technique called tensile testing. Tensile testing involves subjecting a sample of the steel coil to controlled tension until it reaches its breaking point. This test helps determine various mechanical properties of the steel, including yield strength. To inspect steel coils for yield strength using tensile testing, a small strip of the coil is cut and prepared for testing. The strip is placed in a tensile testing machine, which consists of two grips that firmly hold the strip at opposite ends. The machine then applies a steadily increasing force to the strip, causing it to elongate until it ultimately breaks. During the test, the machine measures the force applied and the elongation of the strip. The yield strength is determined by identifying the point on the stress-strain curve where the material begins to deform plastically, or exhibit permanent deformation without any increase in load. The yield strength is typically reported as the stress required to cause a specific amount of plastic deformation, commonly 0.2% or 0.5%. This value represents the maximum stress that the steel can withstand without permanent deformation occurring. By conducting tensile testing on a sample of the steel coil, it is possible to determine its yield strength. This information is crucial for ensuring the quality and reliability of the steel coil, as it indicates the maximum stress it can withstand before permanent deformation occurs. Additionally, this testing method allows for the evaluation of other mechanical properties, such as ultimate tensile strength, elongation, and modulus of elasticity, providing a comprehensive understanding of the steel's performance characteristics.

Q: How do steel coils contribute to sustainability in construction?: Steel coils contribute to sustainability in construction in several ways. Firstly, steel is a highly durable material that has a long lifespan. Steel coils are used in the construction of various structural components like beams, columns, and frames, ensuring the stability and strength of buildings. By using steel coils, the resulting structures require less maintenance and have a longer service life, reducing the need for frequent repairs or replacements. This durability enhances the sustainability of construction projects by reducing the overall environmental impact associated with material waste and energy consumption. Secondly, steel is a highly recyclable material. Steel coils can be easily recycled and reused in new construction projects. The recycling process of steel has a significantly lower environmental impact compared to the production of new steel. Recycling steel coils helps to conserve natural resources, reduce the extraction of raw materials, and minimize energy consumption in steel production. By incorporating recycled steel coils into construction projects, the demand for new steel production is reduced, resulting in lower greenhouse gas emissions and a smaller carbon footprint. Furthermore, steel is a material that can be prefabricated off-site. This means that steel coils can be manufactured in factories in a controlled environment, minimizing construction waste and improving construction efficiency. Prefabricating steel coils reduces the amount of material waste generated on-site and decreases the need for transportation of construction materials, thereby reducing air pollution and energy consumption during construction. Additionally, steel is known for its high strength-to-weight ratio, which allows for lighter and more efficient structures. By using steel coils, construction projects can optimize the use of materials, resulting in reduced material consumption and lessening the overall environmental impact. The lightweight nature of steel coils also facilitates easier transportation, reducing fuel consumption and associated emissions during delivery. In summary, steel coils contribute to sustainability in construction through their durability, recyclability, prefabrication capabilities, and high strength-to-weight ratio. By utilizing steel coils, construction projects can minimize waste, conserve resources, reduce energy consumption, and decrease the environmental impact, ultimately promoting a more sustainable built environment.

Q: How are steel coils cut into smaller sizes?: To achieve smaller sizes for steel coils, there are diverse methods available, which depend on the desired dimensions and quantities. One widely used technique is slitting, where the coil is passed through a set of circular blades that simultaneously make multiple cuts, resulting in narrower steel strips. Slitting is commonly employed to produce narrow coils or strips tailored for specific applications like automotive parts or electrical components. Another option is shearing, which entails cutting the coil into smaller lengths using a straight blade. This method is typically chosen when precise dimensions are necessary, such as in the manufacturing of flat sheets or plates. Shearing can be carried out manually or with automated machinery. Furthermore, laser or plasma cutting techniques can be employed for certain types of steel coils. These methods offer greater flexibility in terms of shape and size, enabling intricate cuts or contours to be created. Laser or plasma cutting is frequently utilized in construction or fabrication projects when specific shapes or profiles are required. In summary, cutting steel coils into smaller sizes involves a range of techniques, including slitting, shearing, laser cutting, or plasma cutting. The selection of the method depends on factors such as the desired dimensions, quantities, and specific requirements of the end product.

Q: Have spent two days making a specialized knife out of 304 stainless steel, after throwing into a log it bent slightly arghhhh. Is it worth continuing to finish it off or start all over again with different kind of steel if so which kind should i use.: just because something is made out of 304 stainless steel does not make it tougher than carbon steel. Stainless steel includes other elements such as chromium. 304 stainless cannot be hardened by heat treatment.

Q: Hey I just got a mini 14 manufactured in 1980. I also had some .223 Wolf steel cased HP rounds (about 200) that i could shoot throught it, but I was just wondering if its a bad idea to use this steel cased ammo...? Only the casing is steel i believe... and the bullet is copper jacketedthanks for your help: Wolf's steel cased ammo isn't bad as practice/plinking ammo, especially for the price, as long as you give your weapons MULTIPLE, THOROUGH cleanings between uses, to be sure and remove ALL the gas fouling left by the Wolf components. HOWEVER.................. As Wolf steel cases are lacquer coated, DO NOT leave a round in a hot chamber, even during short pauses between stages of fire on the range, as the lacquer coating WILL melt, and cause the round to seize in the chamber, causing extraction and jamming problems, especially if the weapon is allowed to cool down with the round left in the chamber. Be extra diligent in removing this lacquer fouling when cleaning the weapon later. I have personally seen other shooters have the case rims ripped off spent cases in the chambers, causing a trip to the gunsmith to have the stuck case removed without damaging the weapon's chamber and actioin, at no minor expense.
