3. How long can we receive the product after purchase?

Usually within thirty working days after receiving buyer’s advance payment or LC. We will arrange the factory manufacturing as soon as possible. The cargo readiness usually takes 15-25 days, but the shipment will depend on the vessel situation.

Q: Suppose you made a sword out of diamond (just follow me here, it's only theoretical). Would it be lighter than a sword of the same size made out of steel?: Just compare the densities. The density of diamond is about 3.5g/mL. While there are different types of steel with different densities, steel is mostly iron, so the density of iron is a good approximation. Iron has a density of 7.87g/mL. Steel is over twice as dense as diamond, so the diamond sword would be lighter.

Q: That's my question, well that and:Steel Pick + Electric Guitar = Trashed Guitar?:D: That's not a question, it's a statement. And how would using any kind of pick trash a guitar? At worst it would harm a $5 set of strings, not the guitar.

Q: Is it just because brass is reloadable? But what makes it reloadable? What does brass bring to the equation that the steel cased ammo can't do?: Steel okorder /

Q: What are the different methods of annealing steel coils?: The different methods of annealing steel coils include full annealing, process annealing, spheroidize annealing, and stress relief annealing.

Q: What are the common coil grades available for steel coils?: There are several common coil grades available for steel coils, each with its own specific properties and applications. Some of the most commonly used coil grades include: 1. Hot Rolled Coils (HRC): This grade is produced by heating a slab of steel above its recrystallization temperature and then rolling it into a coil. HRC coils are known for their excellent weldability and formability, making them suitable for a wide range of applications such as construction, automotive manufacturing, and general engineering. 2. Cold Rolled Coils (CRC): These coils are produced by further processing hot rolled coils through cold reduction, which involves passing the steel through a series of rollers at room temperature. CRC coils have superior surface finish and dimensional accuracy, making them ideal for applications that require a smooth and uniform appearance, such as automotive body panels, appliances, and electrical equipment. 3. Galvanized Coils (GI): Galvanized steel coils are created by coating regular carbon steel coils with a layer of zinc through a hot-dip galvanizing process. This provides excellent corrosion resistance, making GI coils suitable for outdoor applications like roofing, fencing, and structural components. 4. Stainless Steel Coils: Stainless steel coils are manufactured from a variety of grades, with the most common being austenitic (such as 304 and 316) and ferritic (such as 430). Stainless steel coils offer excellent corrosion resistance, high temperature resistance, and aesthetic appeal, making them widely used in industries like food processing, chemical processing, and architecture. 5. Electro-galvanized Coils (EG): Electro-galvanized coils are similar to GI coils, but the zinc coating is applied using an electrolytic process instead of hot-dipping. EG coils have a thinner and smoother zinc layer, making them suitable for applications that require a brighter and more aesthetic appearance, such as automotive parts, appliances, and decorative items. These are just a few of the common coil grades available for steel coils. The selection of the appropriate grade depends on factors such as the intended application, required mechanical properties, and desired aesthetics. It is important to consult with steel suppliers or industry experts to determine the most suitable coil grade for a specific application.

Q: What are the main factors that affect the paint adhesion on steel coils?: The main factors that affect paint adhesion on steel coils are surface cleanliness, surface roughness, presence of contaminants, proper surface preparation, and the type of paint or coating being used.

Q: Can steel coils be rewound?: Yes, steel coils can be rewound.

Q: Can steel coils be customized in terms of size and specifications?: Certainly! Steel coils can indeed be personalized in terms of size and specifications. Although steel coils are normally produced in standard sizes and specifications, they can be customized to fulfill particular requirements based on the customer's preferences. Customization may involve altering the dimensions of the coils in terms of width, length, and thickness, as well as modifying specifications such as the type of steel, surface finish, and coating. Through this process, steel coils can be tailored to suit various applications and industries, ensuring that they meet the specific requirements and performance standards of customers. Industries such as automotive, construction, manufacturing, and appliances often utilize customized steel coils, as precise sizes and specifications are essential for efficient and effective operations.

Q: How are steel coils used in the production of steel washers?: Steel coils are used in the production of steel washers as they are unwound, flattened, and cut into smaller pieces to create the raw material for manufacturing washers.

Q: Hey everyone.I have a whetstone and a honing steel. I purposely tried to make one of my knives less sharp twice to see how well the whetstone and honing steel would work.It even seemed that when I was using my whetstone it wasn't as sharp as it was when I used my honing steel, but when I also used my honing steel after having sharpened my knife on the whetstone, it was razor sharp.I was wondering, is the whetstone only supposed to be used when the knife edge isn't as flat anymore or something? Like, only when it doesn't really have an edge anymore?Please explain your answer.Thanks everyone.: In general, whetstones will actually remove metal in order to sharpen a blade, and the angle they're used at is important too. A steel will just straighten the blade between uses, not actually remove metal. The effect is to make it sharper than it was just before, but only because it's straighter. Using a knife makes the very thin edge kind of flatten or even fold over a bit, or get wavy, etc...so the steel just straightens it back out (imagine what happens when the very thin blade gets pressed down repeatedly on a cutting board, or even cuts through foods repeatedly). (A whetstone is used only when steeling finally just isn't enough to get the blade sharp as needed.) .
