Q:What metals contain steel? It can be anything except soft iron or steel.: tricky situation. look from google. it may help!

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:All of my friends say that if a car made of mostly carbon fiber would crash into a full steel car, or vice versa, the steel car would be DESTROYED and the carbon fiber would drive away, if not, easily repairable.: At a reasonably high speed, both cars would be undrivable. That's by design, not due to the strength/weakness of the materials. The energy in an impact needs to go somewhere. Cars are designed so the body and the frame will bend and break, reducing the impact on the occupants. If the car is too rigid the chances of the occupants being injured increases. Carbon fiber composites do have a better strength to weight ratio than steel but they're also a lot less dense, so the same volume of material will have a similar strength. The primary benefit to carbon fiber is that for a part of the same strength the carbon fiber part will weigh less than the steel part.

Q:Why is it usually scorned by the shooting community to use steel cased ammo (like Wolf)? Always hear corrosive and steel is bad for the extractor/firing pin. Hulp a simpleton out!: I okorder /

Q:Is steel easier to weld?Which is more brittle/less flexible?: Note: the easiest way to join steel to aluminum is to drill holes and BOLT them together...... You cannot WELD steel to aluminum.(except using extreme methods like explosion welding......) For all intents and purposes they are dissimilar metals, meaning they will not bond to each other. Also, aluminum has a much lower melting point than steel. It is possible to join steel and aluminum by *Soldering,* using tin/zinc hard solder. This requires a special flux designed exclusively for soldering aluminum though. The heating process is also a bit delicate as you must avoid overheating the joint. I work as a welder and I've only soldered Al three or four times. Steel is easiest to weld by far. If you set the equipment correctly, a six year-old kid can make a good weld on steel. Aluminum requires special equipment and procedures to weld. It's not easy. The brittleness of aluminum depends on it's alloy content. Most of the aluminum that's used today is not pure, rather it's in the form of aluminum ALLOYS which contain either zinc, magnesium, silicon, or manganese. these elements increase the strength dramatically, but also make it much less ductile. Commercially pure (CP) aluminum is very ductile, but it's also rather weak. Pure aluminum is used to make aluminum foil, as it's so soft and ductile it can easily be rolled paper-thin. The best aluminum alloys can come near in strength to mild steel, but weigh less than half as much as steel. Note that steel itself is an alloy of iron and carbon, Carbon increases the strength of iron in the same way that zinc or magnesium increase aluminum's strength. Most of the commonly used aluminum alloys are somewhat more brittle than mild steel, but not greatly so.

Q:so i've started learning to play guitar in the past few weeks, and i'm using my sister's old guitar which isn't in very good condition, so i'm planning on buying a new one, but which would be better to buy, nylon string or steel string?: It rather relies upon on what type of music you're enjoying, nylon string guitars have a mellow, softer tone than steel strings, the feel of the nylon strings (a minimum of to me) are reliable, in my opinion, i might ought to declare nylon is extra suitable, large for finger choosing and a effective tone. once you're searching for a guitar, you are able to flow out to a close-by guitar save, and attempt the two out for your self, in straight forward terms then will you comprehend for specific.

Q:How are steel coils transported and stored?: Steel coils are typically transported using specialized trailers or railcars, ensuring secure and stable transportation. They are usually stored in warehouses or outdoor yards, stacked in neat rows using specialized equipment like coil racks or cradles. These storage methods help maximize space efficiency and prevent damage to the coils.

Q:I am reading the book The Cure For All Advanced Cancers by Hulda Regehr Clark.She writes for example: cancer can be caused by exposure to heavy metals, like nickel and chromium from stainless steel cookware. Stainless steel cookware releases chromium and nickel, two of the most carcinogenic metals.Are there any studies done measuring how much nickel and cadmium can be released from the regular use of stainless steel cookware?Is this a commonly accepted opinion that use of stainless steel cookware is dangerous?If not stainless steel, what kind of cookware to use? I heard that non-stick cookware also releases some harmful chemicals.: perfluorooctanoic acid is a chemical used to make nonstick cookware. It has been shown to cause cancer in lab animals. The epa has asked companies that use that chemical to phase it out of the cookware, just in case. But it has not been shown to cause cancer in humans. Stainless is not known to cause any type of health problems. Cast iron is healthier and anodized aluminum is great too.

Q:What are the different methods of forming steel coils into sheets?: Steel coils can be formed into sheets using various methods, each having its own benefits and uses. 1. The most commonly employed technique is hot rolling. This involves heating the steel above its recrystallization temperature and passing it through rollers. The rollers apply pressure to reduce the thickness of the steel and elongate it into a sheet. Hot rolling yields smooth sheets suitable for a wide range of applications. 2. Cold rolling, on the other hand, does not require heating the steel. Instead, the steel coil is passed through rollers at room temperature. This process results in sheets with higher dimensional accuracy and a smoother surface finish. Cold-rolled sheets are ideal for applications requiring precise dimensions and a polished appearance, such as automotive body panels and appliances. 3. Annealing and pickling is a method that involves subjecting the steel coil to a heat treatment process called annealing, followed by pickling. Annealing entails heating the steel to a specific temperature and then slowly cooling it to relieve stress and enhance its mechanical properties. Pickling involves removing impurities and scale from the steel surface. These steps are typically performed before hot or cold rolling to ensure a high-quality end product. 4. Galvanizing is a process where steel sheets are coated with a layer of zinc to protect against corrosion. The steel coil is first cleaned and then immersed in molten zinc. The zinc adheres to the steel, forming a protective layer that prevents rust and corrosion. Galvanized sheets find common use in construction, automotive manufacturing, and electrical appliances. 5. Electro-galvanizing is similar to galvanizing, but instead of immersing the steel coil in molten zinc, an electric current is used to deposit zinc onto the steel surface. Electro-galvanizing provides similar corrosion resistance to traditional galvanizing but with a thinner coating. It is often favored for applications requiring thinner and more lightweight sheets. In conclusion, the formation of steel coils into sheets can be achieved through various methods such as hot rolling, cold rolling, annealing and pickling, galvanizing, and electro-galvanizing. Each method offers distinct advantages and is suitable for specific applications based on factors like surface finish, dimensional accuracy, and corrosion resistance.

Q:How are steel coils used in the manufacturing of flooring materials?: Steel coils are used in the manufacturing of flooring materials by being formed into sheets or strips and then processed through various techniques such as cutting, bending, and shaping to create the desired flooring products. The steel coils provide strength, durability, and stability to the flooring materials, ensuring long-lasting and reliable flooring solutions.
