Q:How is steel different than iron?How many different kinds of steel are there?What type is the strongest?Which type is the weakest?: As first answer says, if you look at the number of commercial steel alloys available and consider that any given alloy can be heat treated to a wide range of physical properties, there are thousands and thousands of potential combinations. Technically, steel is an alloy of Fe and C but there are Fe-C alloys that are called cast irons, not steel, and... there are lots of alloy steels which have significant amounts of other elements added like Cr, Ni, Nb, V, Mo, etc. Fe alloys that have a lot of Cr and or Ni added are called stainless steels and there are dozens of them and many of them can be heat treated to produce a wide range of properties. As far as the strongest or the weakest, you have to get really specific about exactly what you mean because some steels are designed for room temperature properties, some are designed for elevated temperature properties, some for static loads, some for impact loads, some for wear resistance, etc, etc.. Steels make up the largest family of metal alloys (by weight and by volume) that humans use. There are a number of reasons for this but the big reasons include: 1) there is a LOT of iron on earth 2) it is relatively cheap to produce 3) you can easily change the physical properties over a every wide range. As an example... you can take a piece of steel that is so brittle it will shatter if you drop it on the floor and heat treat it so you can bend it like a pretzel without cracking and then heat treat it again to make it very strong and tough (resistant to fracture).

Q:What are the common welding techniques used for steel coils?: The common welding techniques used for steel coils include gas metal arc welding (GMAW), flux-cored arc welding (FCAW), and submerged arc welding (SAW). These techniques offer different advantages in terms of speed, efficiency, and weld quality, allowing for diverse applications in the steel industry.

Q:I mean 4 inch thick steel like was used in the WTC buildings, especially WTC 7 which did not get hit by a plane. Can carpeting, desk chairs, water coolers and dry erase boards burn hot enough and long enough to melt steel that is normally made in a blast furnace?: Gavin, the danger posed by steel columns and girders during a fire in a building, is not the danger of the steel melting but of the steel expanding and snapping the bolts that hold all of the steel together. Very high temperatures can be achieved in a building fire because the up-draft caused by the rising hot air, delivers a massive amount of oxygen to the burning carpet, paper and furniture. When a steel frame office tower burns, the heat expands the steel and snaps the bolts. This causes the building to fall-down and not necessarily, burn-down. I am too lazy to look-up the melting point of steel but it is not very high. That is one reason for the columns and girders in steel framed buildings, to be covered in asbestos (which is a fatally toxic material) or magnesium di-oxide.

Q:How is steel sustainable as a building material?How is wood sustainable as a building material?: The choice is yours to make so just click on the proper button for the specific project and then they are right there for you to pick one. The diagrams and instructions will be right there in the computer for you to access at any time or if you prefer you can print them out.

Q:Is it possible to make a homemade blacksmith forge from a washing machine drum made of stainless steel?: The okorder /

Q:We just installed a stainless steel electric stove, what is the best way to keep it clean and shiney?: A kitchen range finished in stainless steel looks professional and clean. Stainless steel stove requires a bit more cleaning than a traditional stove. Use an oil based product. Baby oil or WD40 are the products of choice for many people. You don’t want to put the oil directly onto the appliance, instead just pour some onto the cloth and wipe down the appliance. Routine maintenance on your stainless steel stove is the best way to keep the surface steel clean as well as scratch free.

Q:Can steel coils be painted?: Yes, steel coils can be painted. Painting steel coils is a common practice to enhance their appearance, protect them from corrosion, and provide additional durability. The coils are typically cleaned, prepped, and coated with a primer before applying the desired paint color.

Q:Is there a chemical that can be applied (spraid, brushed, adhere) to a steel surface to decrease the heat conductive properties of the metal (so it doesn't heat up as quickly)?Thanks in advance!: There is, but I don't know what it is made out of. It is probably some fireproof, foam material which acts like insulation. I doubt it is designed to resist abrasion however. Most things which adhere to metal surfaces are not flameproof, and those which do resist fire are not good insulators. For example, the ceramic coating of appliances like stoves and washing machines adhere very well and are fire resistant, but do not insulate. It was the failure of the steel insulation which caused the collapse of the world trade centers. The impact of the airplane tore away all the insulation on the supporting struts of the building and then the fire caused the steel to soften and break. Steel was once insulated by wrapping it in asbestos cloth and then applying plaster over this to form a shell. It did not actually adhere to the steel but it did insulate it, and was fireproof. However asbestos is a cancer hazard and a lot of old buildings are being stripped of their asbestos as a safety precaution. The asbestos can be replaced with fiberglass which is usually duct taped together.

Q:How do steel coils contribute to the aerospace industry?: Steel coils contribute to the aerospace industry in several ways. Firstly, they are used in the manufacturing of aircraft structures and components. Steel coils are often transformed into sheets, plates, or other forms that can be shaped and welded to create various parts of an aircraft, such as wings, fuselage, and landing gear. The high strength and durability of steel make it an ideal material for these critical components, ensuring the safety and reliability of the aircraft. Secondly, steel coils are utilized in the production of jet engines. The high temperatures and extreme conditions that engines operate in require materials with excellent heat resistance and mechanical properties. Steel coils, particularly those made from alloys such as stainless steel or nickel-based alloys, possess the necessary qualities to withstand the demanding environment within a jet engine. These coils can be processed into turbine blades, exhaust system components, and other engine parts, contributing to the overall performance and efficiency of the aircraft. Moreover, steel coils are also used in the construction of aerospace infrastructure and ground support equipment. Steel structures, such as hangars, maintenance facilities, and launch pads, require strong and durable materials to ensure their stability and longevity. Steel coils are often fabricated into beams, columns, and other structural elements that form the backbone of these facilities, providing the necessary strength to withstand the loads and vibrations associated with aerospace operations. In summary, steel coils play a crucial role in the aerospace industry by providing the necessary strength, durability, and heat resistance required for the manufacturing of aircraft structures, engine components, and aerospace infrastructure. Their contribution ensures the safety, performance, and reliability of aircraft, allowing for the advancement of aviation technology and the exploration of new frontiers in aerospace.
