Q: Which is more reactive? Zinc or Steel? And why?: Zinc. Steel is an alloy consisting mostly out of iron, In the reactivity seris, zinc is more reactive than iron. Therefore, zinc is more reactive than steel

Q: Can solution annealing be done on carbon and low alloy steels. please give an explanatory answer.: No. Carbon steel has two different crystal structures, FCC and BCC , depending on the temperature. when you heat steel up and then quench it, it locks the crystal structure into the BCC form. this makes it hard. whereas precipitation hardened austentic stainlesses remain BCC regardless of the temp, so the hardness change is not a function of thermally induced strain. you can anneal carbon steel but the thermal profile is closer to the precipitation profile of PH stainlesses than it is to the Solution annealing profile.

Q: How are steel coils used in the production of agricultural storage tanks?: Steel coils are used in the production of agricultural storage tanks as they are shaped and welded together to create the tank's structure. The coils provide strength and durability to ensure the tank can withstand the weight and pressure of the stored materials.

Q: what is the chemical process that makes steel harder when it is heated and cooled rapidly?what does the heating of it do to the atoms?what does the cooling of it do to the atoms?what makes tempered steel so strong compared to untempered steel?: You can't temper all steels. Generally the material must be a high-carbon or tool steel. Different alloys temper differently, and tempering is usually done to get a specific set of characteristics, so you must know what you are working with and use the right methods and temperature. If you do it wrong, the material may be hard but too brittle for the purpose or have other issues. It can be simple, such as heating to a dull red, carbonizing the surface (use an acetylene rich flame until it blackens the surface) and oil quenching. Do that to a piece of tool steel (like a screwdriver) and it will case (surface) harden it to the point you can't scratch it with a file. Tempering changes the way the molecular structure in the metal is linked and oriented.

Q: Correct me if I am wrong, but steel is an alloy between iron and carbon. Does the carbon in the steel stops the iron from rusting or corroding? Also what is the difference between mild steel and stainless steel?: Mild steel is an alloy. It is the most common form of steel. Mild steel (a so-called carbon steel) is a general term for a range of low carbon (a maximum of about 0.3%) steels that have good strength and can be bent, worked or can be welded into an endless variety of shapes for uses from vehicles (like cars and ships) to building materials. The carbon does not stop the material rusting or corroding. In addition to iron, carbon, and chromium, modern stainless steel may also contain other elements, such as nickel, niobium, molybdenum, and titanium. Nickel, molybdenum, niobium, and chromium enhance the corrosion resistance of stainless steel. It is the addition of a minimum of 12% chromium to the steel that makes it resist rust, or stain 'less' than other types of steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide, called the passive film. The sizes of chromium atoms and their oxides are similar, so they pack neatly together on the surface of the metal, forming a stable layer only a few atoms thick. If the metal is cut or scratched and the passive film is disrupted, more oxide will quickly form and recover the exposed surface, protecting it from oxidative corrosion.

Q: and what are the four main elements in STAINLESS steel? x: Very high carbon steel (0.96 to 2.11%) is hard and not very ductile (difficult to mold or shape). It is also difficult to weld, but has the lowest melting point. As the carbon content is reduced, the steel becomes softer, more ductile and melts at a higher temperature. Stainless steel is an alloy of Iron, Carbon, Chromium. The fourth element would depend upon the grade of steel, but Nickel is probably the most common.

Q: How do steel coils contribute to the manufacturing of electrical equipment?: Due to their unique properties and versatility, steel coils play a crucial role in the manufacturing of electrical equipment. Transformer cores, essential components in electrical equipment, rely on steel coils for efficient energy transfer and reduced energy losses. The magnetic properties of steel make it an ideal material for transformer cores, allowing for the transformation of voltage levels and ensuring proper equipment functioning. In addition, steel coils are widely used in the production of motors and generators, which convert electrical energy into mechanical energy and vice versa. The coil shape of steel enables the creation of electromagnetic fields, necessary for the operation of motors and generators. Moreover, the strength and durability of steel coils enable them to withstand high temperatures and mechanical stresses commonly encountered in electrical equipment. Furthermore, steel coils are utilized in the construction of electrical conductors, including wires and cables, enabling the transmission of electricity from power sources to various electrical devices. Steel's high electrical conductivity ensures efficient power transmission, while also providing mechanical strength and protection against corrosion and wear. The coil shape of steel wires enhances their flexibility, making them suitable for various applications in electrical equipment manufacturing. Overall, steel coils make a significant contribution to the manufacturing of electrical equipment by providing the necessary magnetic properties for transformer cores, enabling the generation of electromagnetic fields in motors and generators, and facilitating efficient power transmission in electrical conductors. Their versatility, strength, and durability make them an indispensable component in the production of reliable and high-performance electrical equipment.

Q: How are steel coils used in the production of steel hinges?: Steel coils are used in the production of steel hinges by being processed and formed into thin strips. These strips are then cut and shaped to create the desired size and shape of the hinges. The steel coils provide the raw material for the hinges, allowing for efficient and precise manufacturing.

Q: Having a new kitchen and would like to know the pros and cons of stainless steel as opposed to white appliances. I can only think of finger marks on the SS, which I believe are difficult to remove. Anyone had both that they could advise please?: A relative had a stainless steel range. It always looked a fingerprinted mess. I have never liked it. To me, it is grey with a sheen. I hate grey. I am a white appliance person all the way. White makes the room look cleaner, brighter and larger and it is easy to keep clean. Stainless is a nightmare to keep clean. Almost forgot to mention, when we bought our house a few years ago, it had a stainless steel range, horribly marked and scratched. I got rid of it, in keeping with white.

Q: I just got a set of all-clad Stainless steel frying pans, they are very nice yet they didn't come w/ instructions to care for them. I have never cooked w/ stainless steel cookware so I really don't know much about them. I was told they should have a lifetime warranty on them, but I don't want to reck them. I would appreciate any information I can get on stainless steel cookware. Thanks.: I have stainless steel as well. i clean them like I would with any pan. however once and a while when the bottems get kind of blackened due to spillage or flames I take one of those magic eraser things to clean them up. once every 2-3 months I polish the outsides with a nice stainless steel cleaner.
