FAQ
1. Is the sample available?
Yes, samples can be sent for test if you need.

Q: What is the width range of steel coils?: The width range of steel coils can vary depending on the specific requirements, but it typically ranges from a few millimeters to several meters.

Q: How are steel coils welded together?: Different methods can be employed to weld steel coils together, depending on the specific requirements and the type of steel being used. Electric resistance welding (ERW) is a common method where an electric current is utilized to generate heat in the coils, melting their edges. Pressure is then applied to join them together. ERW is a cost-effective and speedy technique for welding steel coils. Thinner steel coils are often welded using high-frequency induction welding (HFIW). This involves the use of an induction coil to produce an alternating magnetic field, inducing an electric current in the coils. The resistance of the coils to this current generates heat, causing the edges to melt and form a weld. For thicker and heavier steel coils, submerged arc welding (SAW) is commonly employed. This technique utilizes a granular flux and a continuous electrode that is fed into the weld area. The flux melts, creating a protective shield for the weld pool, while the electrode melts to form the weld. SAW is a robust and efficient method for welding steel coils. In addition to these methods, laser welding and gas metal arc welding (GMAW) can also be utilized for welding steel coils. Laser welding offers high precision and speed, while GMAW, also known as MIG welding, utilizes an electric arc between a consumable wire electrode and the steel coils to create a weld. Irrespective of the welding method employed, successful welding of steel coils hinges on proper edge preparation, maintenance of appropriate heat and pressure levels, and the use of correct welding techniques.

Q: Don't ask me why, but I took my stainless steel ring and I heated it up with my gas stove. I stuck it in there til the metal turned red, and the flame which is normally blue turned orange for some reason when the metal turned red. Anyway, afterwards i cooled it off in water and now it's all discolored and it feels different. It's weighs less and it doesn't feel the same. Plus, it's ugly cause it's all black and blue. What happened? Someone help: Stainless steel has a rating. I don't know what your ring's stainless steel rating is. If you know, you can look it up. The rating will tell you how much steel vs other metal it has (usually Cr and Ni). But usually when you heat the stainless steel to extreme temperature it will discolor due to oxidation. What is worse is that you cooled it off in water (I assumed that you did it while it was still hot). By rapid cooling, you have changed the physical structure of the steel itself. It will change the hardness of the steel. That is why it feels different. Look up on annealing, normalizing, quenching and tempering under heat treatment for steel.

Q: How are steel coils used in construction?: Steel coils are commonly used in construction for a variety of purposes, such as creating structural frameworks, reinforcing concrete, and manufacturing various building components like beams, columns, and trusses. The coils are unrolled and cut to specific dimensions, allowing them to be easily shaped and welded into various structural elements. This versatile material provides strength, durability, and flexibility, making it an essential component in constructing buildings, bridges, and other infrastructure projects.

Q: How are steel coils inspected for flatness variations?: Steel coils are inspected for flatness variations using various methods such as visual inspection, measurement techniques, and automated systems. Visual inspection involves trained personnel visually inspecting the coil's surface for any irregularities or deviations from flatness. Measurement techniques involve using precision instruments such as straight edges, feeler gauges, or laser sensors to measure the flatness at different points along the coil's length. Automated systems use advanced technologies like laser scanning or optical sensors to quickly and accurately detect any flatness variations in the steel coils. These inspections help ensure that the coils meet the required flatness specifications and quality standards.

Q: What are the main factors that affect the flatness of steel coils?: The main factors that affect the flatness of steel coils are the quality and thickness of the steel material, the tension and speed of the rolling process, the temperature and cooling rate during the cooling process, and any potential defects or imperfections in the machinery used for rolling and cooling the steel coils.

Q: How are steel coils used in the manufacturing of wires?: Steel coils are used in the manufacturing of wires by being fed into wire drawing machines where they are elongated and reduced in diameter to the desired thickness. The steel coils provide a continuous supply of raw material, ensuring a seamless production process for manufacturing wires of various sizes and applications.

Q: what do you think about producebility of low density steel? for example: can density of 1020 steel (or ony others) be decreased without any loss of other properties.: 1. A method has been developed for magnetic phase analysis of Fermanal type alloys as-quenched and after aging. 2. The upper limit of alloying to ensure the optimal mechanical properties was determined more precisely for steel 9G28Yu9MVB. For rods aged at 550°C for 16 h the aluminum content should not exceed 9.2% and the carbon content 0.92%. 3. To ensure the optimal mechanical properties of the deformed metal it is necessary to obtain a fine-grained single-phase austenitic structure after quenching. The amount of hardening phase after quenching should not exceed 15–20% (saturation magnetization around 1600 G).

Q: What's the best way to clean granite countertops and stainless steel appliances? My countertops especially always look dull and streaky. Thanks!!!!!!!: I just use my Method brand dish soap to clean my stainless fridge. Then polish it with a dry soft cloth. Then it also smells like cucumber when I'm done. :-)

Q: How are steel coils used in the production of electrical resistors?: Steel coils are used in the production of electrical resistors as the core material for winding wire around. The coils provide a stable structure, allowing the wire to be tightly wound and creating the necessary resistance for regulating electric current flow.
