- 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:What are the different types of steel coil coatings?
- There are several different types of steel coil coatings that are used for various purposes. Some of the most common types include: 1. Galvanized Coating: This is a zinc-based coating that provides excellent corrosion resistance to steel coils. It is often used in outdoor applications where the coils are exposed to harsh weather conditions. 2. Galvannealed Coating: Similar to galvanized coating, galvannealed coating also contains zinc, but it is heat-treated to form an alloy with the steel surface. This type of coating provides better paint adhesion and is often used in applications where the coated coils will be painted or further processed. 3. Pre-painted Coating: As the name suggests, pre-painted coatings are applied to steel coils before they are delivered to customers. These coatings can be made of various materials, including polyester, polyurethane, epoxy, or fluoropolymer. Pre-painted coils are commonly used in construction, automotive, and appliance industries. 4. Electro-galvanized Coating: This coating is applied to steel coils through an electroplating process, where a thin layer of zinc is deposited on the surface of the steel. Electro-galvanized coatings provide good corrosion resistance and are often used in indoor applications or where a thinner coating is desired. 5. Aluminized Coating: Aluminized coatings are made by applying a thin layer of aluminum to the surface of steel coils. This type of coating provides excellent heat resistance and is commonly used in exhaust systems, ovens, and other high-temperature applications. 6. Organic Coatings: Organic coatings are typically applied to steel coils to provide additional protection against corrosion and improve aesthetics. These coatings can be in the form of paints, lacquers, or powder coatings, and they can be customized to meet specific requirements in terms of color, gloss, and durability. Overall, the choice of steel coil coating depends on the specific application, environmental conditions, desired aesthetics, and performance requirements.
- Q:and which one is better?i'm looking into buying some aftermarket headers, but companies make them in both chrome and stainless steel
- For headers go with stainless steel. Chrome holds heat in, and after a while it will discolor due to the high heat of the heads.
- Q:Well actually I was just wondering why people were bashing on stainless so much for katanas. I heard that they don't hold their edge as well as carbon steel blades or Damascus steel. So what makes it so inferior to carbon or other types of steels?
- Stainless okorder /.. More flex will make the sword more resistant to vibration, which can occur from air friction, as well as from tameshigiri. Further, it'll be easier to keep and maintain a good edge on a sword less prone to breaking.
- Q:What are the common standards and specifications for steel coils?
- There are several common standards and specifications for steel coils that are widely recognized and used in the industry. Some of the most common ones include: 1. ASTM A36/A36M: This specification covers carbon structural steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction. 2. ASTM A572/A572M: This specification covers high-strength low-alloy columbium-vanadium structural steel shapes, plates, sheet piling, and bars for applications in bolted, riveted, or welded construction. 3. ASTM A653/A653M: This specification covers steel sheet, zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) by the hot-dip process. 4. ASTM A1011/A1011M: This specification covers hot-rolled, carbon, structural, high-strength low-alloy, high-strength low-alloy with improved formability, and ultra-high strength steel sheet and strip in coils. 5. JIS G3302: This Japanese Industrial Standard specifies the requirements for hot-dip zinc-coated steel sheet (galvanized steel sheet) and strip. 6. EN 10111: This European standard specifies the requirements for continuously hot-rolled low carbon steel sheet and strip for cold forming. 7. ISO 3575: This International Organization for Standardization standard specifies the requirements for hot-dip zinc-coated and zinc-iron alloy-coated steel sheet and strip. These are just a few examples of the common standards and specifications used for steel coils. It is important to note that different industries and applications may have specific requirements, so it is always advisable to consult the relevant standards and specifications for the specific application.
- Q:How are steel coils inspected for formability?
- Steel coils are inspected for formability through a combination of visual inspection, physical testing, and advanced technologies such as laser scanning and digital image correlation. These methods assess the coil's surface condition, dimensional accuracy, and mechanical properties to ensure it meets the required standards for various forming processes.
- Q:If you keep it dry and clean, what steel will last the longest over the years with continued use and sharpening?
- you eventually will wear the blade out. i have seen old guys pocketknives that they used for whittlin and the blades have deep curves in them like khukris from wear. i reccommend, 440 stainless, or something with a rockwell hardness rating above 45.
- Q:What are the dimensions of steel coils used in the mining equipment industry?
- The dimensions of steel coils used in the mining equipment industry can vary depending on the specific application and requirements. However, there are some common dimensions that are often used. Typically, the width of steel coils used in the mining equipment industry can range from 600mm to 2000mm or even wider. This allows for flexibility in the manufacturing process and ensures that the coils can be tailored to fit various equipment sizes and specifications. In terms of thickness, steel coils used in mining equipment can vary from 1.5mm to 20mm or more. The specific thickness is determined by factors such as the type of equipment, the intended use, and the level of durability required. The length of steel coils used in the mining equipment industry can also vary, but commonly falls within the range of 1000mm to 6000mm. Again, this allows for flexibility in the manufacturing process and ensures that the coils can be cut to fit the specific requirements of the equipment being produced. It is important to note that these dimensions are not set in stone and can be customized to meet the specific needs of the mining equipment industry. Manufacturers and suppliers in the industry are often able to provide coils in various sizes and dimensions to accommodate the diverse range of equipment used in mining operations.
- Q:What are the different certifications required for steel coil manufacturers?
- Some of the different certifications required for steel coil manufacturers include ISO 9001, ISO 14001, OHSAS 18001, and various industry-specific certifications such as the American Society for Testing and Materials (ASTM) certifications. These certifications ensure that the steel coil manufacturers meet quality, environmental, and occupational health and safety standards.
- Q:How are steel coils used in the manufacturing of agricultural equipment?
- Steel coils are used in the manufacturing of agricultural equipment as they provide strength, durability, and flexibility. These coils are typically formed, shaped, and welded to create various components like frames, brackets, and supports. The high strength of steel allows for the construction of heavy-duty machinery that can withstand the demanding conditions of agricultural operations.
