- Q: How many percent carbon in low alloy steel and high alloy steel
- Steel is basically an alloy of iron and carbon that has more than 0% carbon and less than 2% carbon. The alloy of carbon and iron with more than 2% carbon is considered cast iron. The bessemer process converts cast iron to steel by injecting oxygen into molter cast iron to burn off the excess carbon. Steel is also modified by adding additional elements like silicon, molydenum, vanadium, chrome, etc.
- Q: What are the different types of steel coil surface treatments for indoor applications?
- The different types of steel coil surface treatments for indoor applications include hot-dip galvanizing, electro-galvanizing, and organic coating.
- Q: How are steel coils used in the production of roofing materials?
- Steel coils are used in the production of roofing materials as they are rolled out and cut into specific dimensions to create metal roofing sheets. These coils provide a sturdy and durable base material that is resistant to weather conditions, ensuring long-lasting and reliable roofing solutions.
- Q: How do steel coils compare to aluminum coils?
- Steel coils and aluminum coils have several key differences that make them suitable for different applications. Firstly, steel coils are known for their strength and durability. They can withstand high temperatures and are less prone to damage compared to aluminum coils. This makes steel coils ideal for heavy-duty industrial applications that require robust materials, such as construction, automotive manufacturing, and oil and gas industries. Steel coils are also more resistant to corrosion, making them suitable for outdoor use in harsh environments. On the other hand, aluminum coils are lighter and have a higher strength-to-weight ratio compared to steel coils. This makes them perfect for industries where weight is a critical factor, such as aerospace and transportation. Aluminum coils are also more malleable, allowing for easier shaping and forming, which is advantageous in industries like packaging and consumer electronics. Moreover, aluminum coils have better thermal conductivity than steel coils, which makes them more efficient in heat transfer applications. This property is beneficial in industries like HVAC (heating, ventilation, and air conditioning) and refrigeration, where efficient heat exchange is crucial. In terms of cost, steel coils are generally more affordable compared to aluminum coils due to the lower cost of raw materials. However, aluminum coils can offer long-term cost savings as they require less maintenance and have a longer lifespan due to their resistance to corrosion. In conclusion, the choice between steel coils and aluminum coils depends on the specific requirements of the application. Steel coils are preferred for their strength, durability, and corrosion resistance, while aluminum coils excel in lightweight applications, heat transfer, and malleability.
- Q: Climbing ropes used by mountaineers are usually made of nylon. Would steel cable of equal strength as the nylon be just as good? What advantages and disadvantages would it have compared to the nylon?
- steel is NOT as flexible and much slipperier if you fall the nylon stretches to slow the victim but a steel cable would stop short and kill you
- Q: What are the different methods of levelling steel coils?
- Different methods are employed to level steel coils, depending on their specific requirements and applications. Some commonly used methods include: 1. Roller Leveling: This method utilizes a series of rollers to apply pressure on the steel coil, effectively reducing residual stresses and eliminating any waviness or curvature. It is commonly used for achieving high flatness in thinner gauge coils. 2. Stretch Leveling: In this method, the steel coil is stretched beyond its yield point to eliminate shape defects. The coil is subjected to tension in a stretcher leveler machine, which elongates the material and removes inherent stresses. It is often used for achieving greater flatness in thicker gauge coils. 3. Temper Milling: This method involves passing the steel coil through a temper mill equipped with work rolls on top and bottom. The temper mill applies tension to the coil, flattening it and improving its shape and surface quality. It is typically used for higher strength steel grades. 4. Corrective Leveling: When the steel coil exhibits significant shape defects like wavy edges or center buckles, corrective leveling is employed. This method selectively removes material from specific areas of the coil to achieve a flat and uniform surface. Laser or plasma cutting machines are often used for this process. 5. Tension Leveling: Similar to stretch leveling, tension leveling applies tension to the coil without exceeding its yield point. Bridle rolls are used to stretch the material, eliminating internal stresses and leveling the coil. It is commonly used for achieving flatness in higher strength and thinner gauge coils. These methods can be used individually or in combination, depending on the specific requirements and desired end product. Each method has its advantages and limitations, and the choice of leveling method depends on factors such as coil thickness, material properties, and desired flatness.
- Q: My mother is in a weilding class, and today she accidentally welded Galvanized Steel. She doesn't feel good and she wants to know what the symptoms are for Galvanized Poisoning from breathing in the Fumes. Please help, I am worried for her.
- Galvanized steel is nothing more than regular steel with zinc added. However, unless you wear the proper gear or ventilate the fumes away, the zinc can cause heavy metal poisoning. As someone who has suffered from it before, usually the symptoms are an upset stomach, feeling queasy, diarrhea, and sometimes hallucinations. If it is bad, you start getting joint pain, a metallic taste in your mouth, and develop a fever. Usually, you can treat mild zinc poisoning by drinking lots of fluids and flushing out your system as much as possible. Still, if the problems persist for more than an hour or so, it can be lethal with many blacksmiths having died as a result of it. If she still feels bad, call a poison control center and tell them she breathed in zinc fumes. They will probably tell you to go to the ER to start treatment. It is not something you wait out.
- Q: What are the different methods of skin pass rolling for steel coils?
- There are several methods of skin pass rolling for steel coils, each with its own unique characteristics and benefits. Some of the most common methods include: 1. Dry Skin Pass: In this method, the steel coil is passed through a set of rolls without the application of any lubricant or coolant. This helps to improve the surface finish of the steel by reducing the thickness variations and imparting a smoother texture. 2. Wet Skin Pass: This method involves the application of a water-based emulsion or coolant during the skin pass rolling process. The coolant helps to reduce friction and heat generated during rolling, resulting in improved surface quality and reduced risk of surface defects. 3. Electrolytic Skin Pass: This technique utilizes an electrolytic solution during skin pass rolling. The steel coil is immersed in the solution, and an electric current is applied to the coil, resulting in controlled surface etching. This method is particularly effective in improving surface cleanliness and removing oxide scale. 4. Temper Mill Skin Pass: This method combines skin pass rolling with a tempering process. The steel coil is rolled through a series of rolls, followed by a heating and cooling process to achieve the desired mechanical properties and surface finish. This method is commonly used for high-strength and automotive-grade steel coils. 5. Tension Leveling: In this method, the steel coil is passed through a series of rolls under high tension. This elongates the steel and helps to reduce residual stresses and shape defects, resulting in improved flatness and dimensional stability. It is important to note that the choice of skin pass rolling method depends on factors such as the desired surface finish, required mechanical properties, and the type of steel being processed. Each method has its own advantages and limitations, and manufacturers typically select the most appropriate method based on their specific requirements.
- Q: I'm ordering a Pair of tongs(a tool used to dig quahogs in bays that scrapes the bottom constantly) and what type of metal would be the best to fabricate it, steel or stainless steel?
- S/S. We use clam rakes around here, I think they have a S/S basket with steel teeth to dig into the sand. By the way, I believe S/S is just steel with nickel added, but I could be wrong.
- Q: If rebar steel is welded together as opposed to 'tied' does it decrease the strength of the steel?
- The term tensile capability refers back to the quantity of tensile (stretching) tension a fabric can stand up to till now breaking or failing. the main suitable tensile capability of a fabric is calculated by technique of dividing the element of the fabric examined (the go section) by technique of the rigidity located on the fabric, regularly expressed in terms of pounds or plenty in step with sq. inch of fabric. Tensile capability is an significant degree of a fabric's means to accomplish in an utility, and the size is broadly used whilst describing the residences of metals and alloys.
