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:How are steel coils processed for pickling or oiling?: Steel coils are processed for pickling or oiling by first being cleaned and then passed through a series of chemical baths or mechanical processes to remove any impurities or scale on the surface. This is followed by rinsing and drying the coils, after which they can either be pickled in acid to remove oxides or coated with oil to prevent corrosion.

Q:What are the common challenges faced in steel coil production?: Some common challenges faced in steel coil production include maintaining consistent quality control, managing high production volumes efficiently, ensuring proper handling and storage to prevent damage, dealing with fluctuations in raw material prices, and addressing environmental concerns related to energy consumption and emissions.

Q:I am trying to clean up a stainless steel back splash and some kitchen appliances that have brown spots that look like rust spots. I was able to remove most of them with stainless steel cleaner but does anyone know any tricks?: if okorder /

Q:Moravia’s coal and steel industries face challenges because they _____. a.do not run efficientlyb.have run out of resourcesc.have a declining work forced.have not privatized: do not run efficiently is the correct answer

Q:How are steel coils used in the production of electrical connectors?: Steel coils are used in the production of electrical connectors as they provide a strong and durable core component. The coils are wound into the desired shape and size, and then further processed to create the necessary conductive pathways for electrical current. This ensures stability, strength, and efficient conductivity in the connectors, making them suitable for various electrical applications.

Q:When steel is cast, does it become weaker/more brittle or anything of this nature? what are the side effects of steel casting on the steel itself?How can you correct these?: It contains too many air bubble spacing and too many impurity that make it easily to be broken apart. Melt it down again with high heat to remove most impurity, after this process,it becomes iron.

Q:I want to make a stock removal knife, but I am really confused about what steel to use. I am just a beginner but I read o1 steel is great? Also I am kind of on a budget.: O-1 is an excellent steel. If you've never made a knife before find an old file and use it. My first knives weren't that good, it took a little practice to get the geometry right so be prepared to burn some steel. The advantage of a file is it is already hardened, unless you have a torch or forge that will be near imposable for you to do. The most important thing in knife making is the heat treating. The best steel wont perform like it's supposed to. If you decide to use a file grind your blade out, keep the steel cool; do not let it get any color in it (brown, blue, purple) as this destroys the temper. When your finished put the blade in the oven at 400 deg for an hour. It should have a good hardness for a knife then. As for me, I use old car springs(5160), saw blades(L-6) for many of my blades, Good luck.

Q:What are the different types of steel coil cutting tools?: In the market, one can find a variety of steel coil cutting tools. These tools have been specifically designed to efficiently and accurately cut steel coils. Some of the commonly used types of steel coil cutting tools include: 1. Slitting shears: These shears are widely utilized to cut steel coils into narrow strips. Equipped with multiple blades, slitting shears offer clean and precise cuts without causing any damage to the material. They are typically employed in high-volume production and are capable of handling different thicknesses of steel coils. 2. Rotary shears: Another commonly used cutting tool for steel coils is the rotary shear. These shears consist of rotating blades that shear through the material as it passes through them. Rotary shears are perfect for cutting medium to thick steel coils and are known for their high cutting speed and accuracy. 3. Guillotine shears: Guillotine shears are heavy-duty cutting tools that can handle thick steel coils. They operate by exerting a downward force to cut through the material in one clean stroke. Renowned for their power and precision, guillotine shears are suitable for cutting large volumes of steel coils. 4. Laser cutting machines: Advanced cutting tools like laser cutting machines employ a high-powered laser beam to cut through steel coils. These machines offer precise and intricate cuts with minimal heat distortion. Laser cutting machines are ideal for cutting complex shapes and patterns on steel coils. 5. Water jet cutting machines: Water jet cutting machines utilize a high-pressure stream of water mixed with abrasive particles to cut through steel coils. This method provides high accuracy and does not generate heat, making it suitable for cutting heat-sensitive materials. Water jet cutting machines can cut through various thicknesses of steel coils and produce smooth edges. Each type of steel coil cutting tool has its own advantages and is suitable for different applications. The choice of tool depends on factors such as the thickness of the steel coil, required precision, production volume, and budget.

Q:How are steel coils used in the production of furniture?: Steel coils are used in the production of furniture as a key component for creating sturdy and durable frames. These coils are typically used in the construction of sofas, chairs, and other seating furniture to provide structural support and ensure long-lasting quality.
