Q: i have searched high and low, but can't find information anywhere!bainitic and pearlitic steels are too in depth, just would like to know if it is hsla steel, or mild steel, or stainless steel etc...thank you in advance :): Well i guess they have to ( engineers ) take into account stuff like tensile stress and crap and then also the amount by which it contracts and expands during extremme tempertures if i were you put this question under the engineering section. It might lead to a right on the nail answer and also there ought to be a log book which gives us like you know the best steel for railroad maufacture. Architectural engineers or construction engineers are always goin around with books bookworms to be more precise. haha anyways best of luck mate.

Q: I mean, besides the light weight and other graces of Aluminium and Carbon, Steel frames are absolutely out-dated and they have nothing to do these days... or it is still possible to enjoy a nice ride on our heavy old pals?: Au contraire; many great bikes are still steelies. Today's steel is much lighter than 10 yrs ago.

Q: Does anyone know the lyrics to steel driving man by Dailey and Vincent. I would really appreciate it: I okorder /

Q: How are steel coils used in the manufacturing of pipelines?: Steel coils are used in the manufacturing of pipelines by being formed into large cylindrical shapes that serve as the main body of the pipelines. These coils are unrolled and then welded together to create a continuous pipeline, providing strength and durability to transport fluids or gases over long distances.

Q: I'm doing a project on stainless steel dining utensils and its a little more difficult than i thought it would be. There are no sites on the web that tells the creator or when it was first used. There's no sites that that i can see of that talk about the history of stainless steel dining utensils, only dining utensils in general. Please help, i can't change my project now ):: The booklet 100 years of WMF (WMF: Württembergische Metallwarenfabrik / Wurttemberg Metal Ware Factory) includes the patent application (or better: trade mark application) for stainless Cromargan Steel for the production of cutlery in 1926. Cromargan was the company's fantasy name for stainless Krupp V2A steel. Page 86 (unfortunately WMF is a German company, the booklet therefore is in German). Has nice pictures anyways. Appendix: I found the text (a bit cut however) in English language (without images and booklet, just HTML). See below.

Q: How are steel coils used in the production of industrial boilers?: Steel coils are used in the production of industrial boilers to form the main body and components of the boiler, providing strength and durability. The coils are first shaped into the desired boiler structure, such as the shell and tubes, and then welded together to create a sturdy and leak-proof vessel. Additionally, the coils are often used to manufacture the heat exchangers and other critical parts of the boiler, ensuring efficient heat transfer and reliable operation.

Q: What is the weight of a typical steel coil?: The weight of a typical steel coil can vary significantly depending on its size, thickness, and type of steel used. However, a typical steel coil can range anywhere from a few hundred kilograms to several tonnes in weight.

Q: Can we construct a barn using steel and will it be a durable one?: Steel barns in the USA is the going fad; they are both strong and economical; and some companies offer DIY kits

Q: What are the factors affecting the formability of steel coils?: There are several factors that can affect the formability of steel coils. Some of the key factors include the composition of the steel, its mechanical properties, the thickness and width of the coils, the temperature at which the forming process takes place, the type and amount of lubrication used, and the speed and pressure applied during forming. Additionally, the presence of defects or impurities in the steel can also impact its formability.

Q: How are steel coils manufactured?: Steel coils are manufactured through a series of processes that involve the transformation of raw materials into the final product. The manufacturing process begins with the extraction of iron ore, which is then smelted in a blast furnace to produce pig iron. The pig iron is further refined in a basic oxygen furnace to remove impurities and adjust the carbon content. Once the molten steel is obtained, it is continuously cast into large slabs or billets. These slabs are then rolled into thinner sheets or strips through a process called hot rolling. This involves passing the steel through a series of high-pressure rollers, which reduce the thickness and shape the material to the desired dimensions. During this process, the steel is also treated to improve its mechanical properties, such as strength and hardness. After hot rolling, the steel is pickled and cleaned to remove any scale or impurities on the surface. It is then cold rolled to further reduce the thickness and improve the surface finish. Cold rolling involves passing the steel through a set of rollers at room temperature, which increases its strength and dimensional accuracy. To form steel coils, the cold-rolled steel is typically wound tightly into a large coil shape. This is achieved by feeding the steel strip through a series of rollers that gradually wind it into a spiral. The coils are then typically annealed to relieve internal stresses and improve the material's formability. Finally, the steel coils are coated or treated, depending on their intended use. This can involve applying a protective coating, such as zinc or paint, to enhance corrosion resistance or providing a specific surface treatment for improved adhesion in subsequent processes. Overall, the manufacturing of steel coils is a complex process that involves several stages, including smelting, casting, hot rolling, cold rolling, coiling, and surface treatment. Each step contributes to the final product's quality and properties, ensuring that steel coils meet the required specifications for various industrial applications.
