Q:in a lab at school we did heat treatment of steelwhat are the possible phases present in the steel sample in as-received, as-quenched and as-tempered conditions? specifically when is it ferrite, austenite and pearliteis the steel originally in the ferrite phase? then when headed turns into austenite and when quenched martensite is formed and when tempered cermentite is formed...........where is pearlite involved and am i correct about the ferrite?

hey from what i learned in uni last sem, steel is originally ferrite form at first at room conditions. it will undergo poly morphic transformation to become FCC structure austenite form at 912 degree celcius. under conditions, it can become pearlite (which is a combination of ferrite and cementite) or bainitie( a finer form of pearlite). queching conditions to room temperature will form martensite which is the strongest but brittle steel form. tempered cementite is formed when we quench it and then raise temperatures before sir cooling. hope it helps, pls vote me best answer is i deserve it. thanks

Q:What are the common coil storage methods?

The common coil storage methods include stacking coils vertically, using coil cradles or racks, and storing them horizontally on pallets or on the ground.

Q:What metals contain steel? It can be anything except soft iron or steel.

Metals do not contain steel. Steel is an alloy of purified iron and carbon, and sometimes with other metals, such as nickel, chromium, or molybdenum to make it stainless or to change its hardness or other properties. It's like asking what cereals contain Cheerios. It doesn't really make sense. Other metal alloys contain iron, which is an element and the main ingredient of steel. Maybe you should be asking which metal alloys contain iron? That's more like asking which cereals contain whole grain oats. Now that's a question that can be answered by reading the ingredients labels on your standard boxes of metal alloys :-)

Q:Can you reload spent casings if they are steel?

Steel Casings

Q:Iron melts faster when there will be low carbon in Iron.During steel making the molten Iron gets purified and alloying being done through the process. How the carbon is being controlled at Iron melting stage and what it is called?

It's not really that hard. You can use your charcoal grill to do it. First build a large fire in it and then bury the steel in the coals. It'll only take about ten minuites or so for the steel to heat through. Then pick it out of the coals with tongs and drop it into a bucket of water. Repeat as desired. Eventually it'll get as brittle as glass. To fix this, you must anneal the metal. Again heat the metal in the coals, only this time let it stay there until the coals go all the way out all by themselves. Next day when all the way cool, Take it out and clean it off. Viola!, you have hardened steel.

Q:I have two theories, which one's correct?My book says that steel is made up of 98% iron and 2% carbon.98% of iron's molar mass (55.85 g/mol) is 54.733.2% of carbon's molar mass (12.01 g/mol) is .2402.If you add them up that gives you that steel has a molar mass of 54.97 g/mol.However, steel's chemical formula is Fe(3)CThat would make it's molar mass 179.56 g/mol.( Because 3(55.85) + 12.01 = 179.56 )Which one is correct?

Steel is an alloy - a mixture not a compound; it doesn't have a chemical formula. Only elements and compounds have molecular weights, not mixtures that aren't composed of a uniform molecule, so neither answer is correct.

Q:What are the common methods of recoiling steel coils?

Manufacturers and customers have various options when it comes to recoiling steel coils. One frequently used method is slitting, which employs rotating circular blades to cut a wide steel coil into narrower strips. This results in multiple smaller coils with desired widths. Slitting is commonly employed to create coils of different sizes for diverse applications. Another technique is known as cut-to-length (CTL) recoiling, where the steel coil is cut into specific lengths according to the customer's requirements. This involves passing the coil through a straightening and leveling machine, followed by a flying shear that cuts the steel into the desired lengths. CTL recoiling is particularly useful in industries that demand precise and uniform steel lengths, such as construction or automotive. Furthermore, there is a method called coil-to-coil recoiling. This process involves rewinding the steel coil onto a new coil with the desired dimensions and properties. Coil-to-coil recoiling is typically utilized when the original coil needs resizing, reconditioning, or rerolling for further processing or transportation purposes. Specialized recoiling machines ensure proper tension, alignment, and winding of the steel coil onto the new coil. In conclusion, the recoiling of steel coils can be accomplished through various methods, including slitting, cut-to-length recoiling, and coil-to-coil recoiling. Each method offers its own advantages and is chosen based on factors such as required coil dimensions, precision, efficiency, and the specific needs of the industry or customer.

Q:How are steel coils used in the production of pipes and tubes?

Steel coils are used in the production of pipes and tubes by being fed into a pipe or tube mill, where they are unraveled, formed, and welded together to create the desired size and shape of the pipe or tube.

Q:How are steel coils processed?

Steel coils are processed through a series of steps including pickling, cold rolling, annealing, and coating to achieve desired thickness, strength, and surface finish, making them ready for various applications in industries like automotive, construction, and manufacturing.

Q:What are chemical properties of high speed steel? Physical properties?What is high speed steel used for? One interesting fact about high speed steel?

wikipedia: High speed steel (often abbreviated HSS, sometimes HS) is a material usually used in the manufacture of machine tool bits and other cutters. It is often used in power saw blades and drill bits. It is superior to the older high carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high speed steel. At room temperature, in their generally recommended heat treatment, HSS grades generally display high hardness (above HRC60) and a high abrasion resistance (generally linked to tungsten content often used in HSS) compared to common carbon and tool steels. see reference for more info .
