- Q:what is magnetic steel used for and if it can be used for producing kitchenwares utenils like stainless steel basines,mugs and bowls.
- Magnetic steel rusts. That's why kitchenware is often made out of stainless. You can't turn magnetic steel into stainless, sorry. Metalurgy is a complicated subject, and is all about different alloys. It's far too involved to explain in a few paragraphs here, but no, they're not interchangeable in this case unless you want to produce kitchenware that rusts.
- 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:How are steel coils processed for stamping or forming?
- Steel coils are processed for stamping or forming through a series of steps which generally include uncoiling, leveling, lubricating, feeding, stamping/forming, and cutting. Initially, the steel coil is uncoiled to remove any tension and then passed through a leveling machine to ensure a flat surface. Lubrication is applied to reduce friction during the stamping/forming process. The coil is then fed into a stamping or forming machine, which shapes it according to the desired design. Finally, the formed steel is cut into individual pieces, ready for further use or assembly.
- Q:Hello... I'd like to know where I can find proof of this answer as well please. My own searching didn't come up with anything concrete.I'd like to know how much the ambient temperature inside of a hollow steel tube would rise by if the outside of that tube was exposed to an 1100 degree flame for a period of 3 seconds.If specifics help, they are something along the lines of 3.125 O.D. tube, 0.35 wall thickness. High grade steel, can't be more specific than that sorry.Thanks for any answers!
- I can asnswer this from practical experience. If the tube is sealed, temperature would rise approx. 25 deg F. If the tube were open the temperature would be less that a 10 deg F rise. The exact answer can be found in any book on thermodynamics.

They also focus on continuous improvement, employee training, and regular maintenance of equipment to ensure smooth operations and minimize waste generation.
- Q:How are steel coils heat treated?
- Steel coils are heat treated using a process called annealing. Annealing is a heat treatment technique in which the steel coils are heated to a specific temperature and then slowly cooled down. This process helps to relieve any internal stresses within the steel, improve its mechanical properties, and enhance its overall performance. The heating process involves raising the temperature of the steel coils to a critical point, typically between 800°C and 900°C, depending on the specific grade and desired outcome. The coils are then held at this temperature for a specific period of time, allowing for the transformation of the steel's microstructure. Once the desired time has elapsed, the heated steel coils are slowly cooled down in a controlled manner. This slow cooling process is vital as it allows the steel to undergo a gradual transformation, resulting in a more uniform and refined microstructure. This controlled cooling also helps to minimize the formation of internal stresses, which can potentially weaken the steel. The annealing process can be performed in different atmospheres, such as air, nitrogen, or hydrogen. The choice of atmosphere depends on the specific requirements and properties desired for the steel coils. For instance, annealing in a protective atmosphere like nitrogen or hydrogen can help prevent oxidation or decarburization of the steel surface. Overall, heat treating steel coils through annealing is a critical step in enhancing their mechanical properties, improving their formability, and achieving the desired characteristics for various industrial applications.
- Q:How are steel coils used in the manufacturing of construction formwork?
- Steel coils are used in the manufacturing of construction formwork to create the framework and support structures needed for pouring concrete.
