Q:Can steel coils be stored in unheated warehouses?: Yes, steel coils can be stored in unheated warehouses as long as proper precautions are taken to prevent moisture and corrosion.

Q:This needs to be in a percentage by mass. Could you please also reference where this info has come from. Thanks.: pl. be specific about the type of steel: (Steel is a metal alloy whose major component is iron, with carbon content between 0.02% and 1.7% by weight. Carbon is the most cost effective alloying material for iron, but many other alloying elements are also used.[1] Carbon and other elements act as a hardening agent, preventing dislocations in the iron atom crystal lattice from sliding past one another. Varying the amount of alloying elements and their distribution in the steel controls qualities such as the hardness, elasticity, ductility, and tensile strength of the resulting steel. Steel with increased carbon content can be made harder and stronger than iron, but is also more brittle. The maximum solubility of carbon in iron is 1.7% by weight, occurring at 1130° Celsius; higher concentrations of carbon or lower temperatures will produce cementite which will reduce the material's strength. Alloys with higher carbon content than this are known as cast iron because of their lower melting point.[1] Steel is also to be distinguished from wrought iron with little or no carbon, usually less than 0.035%. It is common today to talk about 'the iron and steel industry' as if it were a single thing; it is today, but historically they were separate products. Currently there are several classes of steels in which carbon is replaced with other alloying materials, and carbon, if present, is undesired. A more recent definition is that steels are iron-based alloys that can be plastically formed (pounded, rolled, etc.). Iron alloy phases : Austenite (γ-iron; hard) Bainite Martensite Cementite (iron carbide; Fe3C) Ferrite (α-iron; soft) Pearlite (88% ferrite, 12% cementite) Types of Steel : Plain-carbon steel (up to 2.1% carbon) Stainless steel (alloy with chromium) HSLA steel (high strength low alloy) Tool steel (very hard; heat-treated) Other Iron-based materials : Cast iron (2.1% carbon) Wrought iron (almost no carbon) Ductile iron)

Q:How are steel coils coated or painted?: Steel coils are typically coated or painted using a process known as coil coating. This involves a series of steps including cleaning, pretreating, applying primer, and applying the final topcoat. The coils are first cleaned to remove any dirt or contaminants. They are then pretreated to enhance adhesion and corrosion resistance. After that, a primer is applied to provide a base layer for the paint. Finally, the desired topcoat is applied using various methods such as roll coating, spray coating, or electrostatic coating.

Q:Can steel coils be used in high-temperature applications?: Yes, steel coils can be used in high-temperature applications. Steel is known for its excellent strength and resistance to heat, making it a suitable material for various industrial processes that involve high temperatures. It can withstand and maintain its structural integrity even under extreme heat conditions.

Q:I am making a sword of 1060 carbon steel and would like to know how to heat treat it once it's ready, could anyone help please?: I've okorder for back and forth communication. I could type up some lengthy post, you'd read it and be like I don't have that piece of gear and all my time is wasted.

Q:I work at a tool store. I told my boss last week we needed more pruning shears so he did get more of all kinds. Thing is out of all of the shears he brought Two of different kinds say they are made out of Japanese steel. I have never heard of Japanese steel so now i ask you (the public) whats the difference between it and steel from the US or any other country? Those shears are worth more then the ones he gets from Mexico and China and even more than Black and Decker, Fiskars, etc but not more then Corona brand ones.: I doubt japanese steel has any special quality in its own, but they might just be higher quality shears. For example, Chinese qualities are good depending on what they are, but are usually not professional made with the greatest equipment. Same for Mexico. The company that makes them might just put more effort into making sturdier and sharper shears and thus make them more expensive, but Corona might make them a bit better so they are priced less than Corona's.

Q:How are steel coils used in the production of electronic devices?: Steel coils are used in the production of electronic devices for various purposes, such as creating magnetic fields, providing structural support, and acting as conductors in transformers and inductors. These coils are typically wound around a core material, such as ferrite or laminated iron, to enhance their magnetic properties and improve their performance in electronic circuits.

Q:I also heard Stainless holds up better againts rust, blue steel needs more care.: They have different properties. Bluing on steel is a surface treatment that helps inhibit rust, but doesn't prevent it. It will wear off with use over time, but can be redone. Stainless steel refers to a particular type of steel alloy, usually incorporating nickel and chromium, that is highly resistant to rust on its own, so doesn't need a surface treatment. Because the steel itself is what is rust resistant, that property can't wear off. All other things held equal, the carbon steel that bluing is typically applied to tends to be slightly more rigid and brittle than stainless steel. It may hold an edge better than stainless. In most applications, those differences are small enough not to matter for practical purposes. For example, both knives and guns are made with blued steel and stainless steel. Which a person gets is usually a matter of preference (unless you're, say, a professional restaurant chef whose knives have to hold a fine edge through constant hard use).

Q:Will hot dip galvanizing affect the properties of the steel: depends on what your are dipping...i.e what its composition and properties were, was it a spring steel prior?

Q:What is the average shelf life of a painted steel coil?: The average shelf life of a painted steel coil can vary depending on various factors such as the quality of paint used, environmental conditions, and storage practices. However, under normal conditions, the average shelf life of a painted steel coil is typically around 1 to 2 years.
