Q: I want to know if it is possible to make regular steel stainless.From what I understand stainless consist of chromium about 10 percent I think.Any way I'm wondering if properties can be added in a process or can this only be possible during actual manufacturing of the steel.And I'm not talking about chrome like stainless steel that's not to shiny.: no an alloy essentiallly does not exibit its constituent properties if you want to add anymore the thing should be molten and hot and homogenous homogenous being the key word and no ss essentiallly mean that thing only

Q: i have a sword and some knives that have this grade steel. so is it a high grade or low grade? and how can i tell the differance between a high grade and a low grade?: Type 440—a higher grade of cutlery steel, with more carbon in it, which allows for much better edge retention when the steel is heat treated properly. It can be hardened to Rockwell 58 hardness, making it one of the hardest stainless steels. Also known as razor blade steel. Available in three grades 440A, 440B, 440C (more common) and 440F (free machinable).

Q: How are steel coils coated for added protection?: Steel coils are coated for added protection through a process called coil coating. During this process, the steel coils are cleaned and treated with a primer to promote adhesion. Then, a topcoat is applied, which can be a variety of materials such as paint, polymer, or zinc-based coatings. This coating provides a protective barrier against corrosion, abrasion, and other environmental factors, enhancing the durability and lifespan of the steel coils.

Q: a concrete or steel building?also, what is the density of concrete and steel? is concrete heavier in steel for the same volume?: Steel is heavier than concrete for the same volume, however steel buildings are generally lighter. This is because steel buildings utilize high strength of steel, so volume of steel in steel buildings is much smaller than volume of concrete in concrete buildings. In another words in steel buildings much less volume of material is needed for the same strength compared to concrete buildings.

Q: Several reading methods of steel tape measure: Precise steel tape factory and after a period of time must go through the verification and indicate the verification of temperature, tension and feet. Feet marked on the length of its nominal length, and the difference between the actual length is called length correction delta l ruler by different tension will make feet long. To avoid this change requires the use of steel tape according to the scale mark force of steel tape. At different temperature the foot will change with the temperature so it is necessary to use t as variable function to represent the feet long, this is the ruler length equation, its general form:

Q: How are steel coils annealed for improved properties?: Steel coils are annealed for improved properties through a process called annealing. This involves heating the steel coils to a specific temperature and then slowly cooling them to relieve internal stresses and create a more uniform and refined grain structure. This annealing process helps improve the steel's ductility, hardness, and overall strength, making it more suitable for various applications.

Q: How are steel coils used in the manufacturing of construction reinforcement bars?: Steel coils are used in the manufacturing of construction reinforcement bars by being processed through a series of rolling mills. These coils are first uncoiled and then heated to a high temperature, allowing them to be easily shaped and molded into the desired bar shape. The coils are then passed through a series of rollers that gradually reduce their thickness and increase their length. This process gives the steel bars the necessary strength and durability to be used as reinforcement in construction projects.

Q: What are the common maintenance practices for steel coils?: Common maintenance practices for steel coils include regularly inspecting for any signs of corrosion, cleaning the coils to remove dirt and debris, applying protective coatings or paint to prevent rust, storing the coils in a dry and well-ventilated area, and ensuring proper handling and transportation to avoid any damage. Additionally, it is important to monitor and control the humidity levels around the coils to prevent moisture buildup, which can lead to corrosion.

Q: I want to replace the old refrigator within the next 6 months........ Is the trend to buy a stainless steel refrigerator? Some magazines and internet sites are pointing me that direction. What are the pro's and con's ? I like the color bisque, or cream-color as well, or better, than stainless steel. What would be the reasons to buy stainless steel...is it becoming the most popular color ?: I'm looking too and certainly the designer trend is to buy stainless steel. They look classy, shiny and bring a darker wood kitchen more life. However, there are companies that have put out fingerprint/smudge free stainless models. I have found their surfaces don't retain fingerprints - do test them in the store.If you have small children, stainless isn't the best choice. I love the look and practicality of the French Door fridges - great for smaller spaces. I was all set to buy an LG fridge and now I'm hearing that they're going on fire? Be sure to check Consumer Reports before you buy. Many of the cheaper models are now made in Mexico. I do notice the quality difference when I'm opening and closing fridge doors in the showrooms.

Q: What are the different types of steel coil surface finish treatments?: There are several different types of steel coil surface finish treatments available, each serving a specific purpose and providing unique characteristics. Some common types include: 1. Hot Rolled: This is the most basic and common type of steel coil surface finish treatment. It involves heating the steel above its recrystallization temperature and then rolling it to achieve the desired thickness. This process results in a rough surface texture. 2. Cold Rolled: Unlike hot rolled, cold rolled steel coil undergoes a process where it is rolled at room temperature. This treatment produces a smoother surface finish with improved dimensional accuracy and tighter tolerances. 3. Galvanized: Galvanization is a process where a protective zinc coating is applied to the steel coil surface. This treatment not only enhances the appearance but also provides excellent corrosion resistance, making it suitable for outdoor applications. 4. Electro-galvanized: Similar to galvanized steel, electro-galvanized steel coil is coated with a zinc layer. However, the coating is applied through an electroplating process, resulting in a thinner and more controlled coating. 5. Pre-painted: Pre-painted steel coil surface finish treatment involves applying a layer of paint or other protective coating before the product is delivered to the customer. This treatment enhances the appearance and provides additional protection against corrosion. 6. Stainless Steel: Stainless steel coil surface finish treatment involves passivating the steel to remove any impurities or contaminants on the surface. This process improves the resistance to corrosion and gives the steel a clean and smooth appearance. 7. Embossed: Embossing is a surface finish treatment where a pattern or design is pressed into the steel coil surface. This treatment enhances the aesthetics of the product and can provide additional grip or texture depending on the specific design. 8. Brushed: Brushing is a treatment where a fine abrasive material is used to create a brushed pattern on the steel coil surface. This finish provides a unique texture and can help mask scratches or other imperfections. These are just some of the various types of steel coil surface finish treatments available. The choice of treatment depends on the specific requirements of the application, such as appearance, corrosion resistance, or functionality, and it is important to select the most appropriate treatment to ensure the desired outcome.
