1, carbon steel rimmed steel sheet (GB3274-88)
Steel rimmed steel sheet as the name suggests is made by boiling hot rolled steel plate made of ordinary carbon structural steel. Rimming steel deoxygenation is a complete steel, steel liquid oxygen content is higher, when molten steel after the injection mould, carbon oxygen reaction to produce large amounts of gas, resulting in liquid steel was named after boiling state. Rimming steel with low carbon content, and because no FeSi deoxidization, so steel containing silicon amount<0.07%. Boiling steel outer layer is crystallized in the boiling state, so the surface clean, compact, good surface quality, good processing performance. Rimming steel no large shrinkage hole, deoxidizer used less, low cost of steel. Rimming steel heart of impurities, with the serious segregation, mechanical heterogeneity, more gas in steel, low toughness, cold brittleness and aging sensitivity is larger, the welding performance is poor, so it does not apply to manufacturing under impact load, welding pieces of the structure and other important components work under low temperature.

- Q: Are steel sheets heat resistant?
- Yes, steel sheets are generally heat resistant due to their high melting point and ability to withstand high temperatures without deforming or melting.
- Q: What is the maximum size of steel sheets available?
- The maximum size of steel sheets available can vary depending on the manufacturer and specific requirements. However, commonly available steel sheets can range in size from 4 feet by 8 feet (1.2 meters by 2.4 meters) to larger dimensions such as 10 feet by 20 feet (3 meters by 6 meters).
- Q: What are the problems encountered in the construction of steel sheet piles? How to deal with
- During piling, sometimes large blocks of stone or other unknown obstacles are encountered, which results in inadequate penetration of steel sheet piles and the use of corner piles or arc piles to bypass obstructions.
- Q: Can the steel sheets be used for insulation purposes?
- No, steel sheets are not typically used for insulation purposes. Steel is a highly conductive material, meaning it transfers heat and cold very easily. This makes it unsuitable for insulation, as it would not effectively prevent the transfer of thermal energy. Insulation materials, on the other hand, are specifically designed to reduce heat transfer and improve energy efficiency in buildings and other structures. Common insulation materials include foam, fiberglass, and cellulose, which have much higher resistance to heat flow compared to steel.
- Q: What is the maximum temperature resistance of steel sheets?
- The maximum temperature resistance of steel sheets varies depending on the specific type of steel and its composition. However, in general, stainless steel has good heat resistance and can withstand temperatures up to about 1200 degrees Celsius (2200 degrees Fahrenheit) without losing its strength or structural integrity. High carbon steels, on the other hand, can handle temperatures up to about 900 degrees Celsius (1650 degrees Fahrenheit) before they start to lose their mechanical properties. It is important to note that these temperature limits are approximate and may vary depending on factors such as the duration of exposure, the presence of other elements or impurities in the steel, and the specific application in which the steel sheets are being used. Therefore, it is always advisable to consult the manufacturer's specifications or conduct further research to determine the exact maximum temperature resistance of a particular type of steel sheet.
- Q: What is the difference between zinc-coated and zinc-aluminum coated steel sheets?
- Zinc-coated steel sheets are made by applying a layer of pure zinc onto the surface of the steel through a process called galvanization. On the other hand, zinc-aluminum coated steel sheets are created by combining zinc and aluminum in a specific ratio before applying it to the steel surface. The addition of aluminum enhances the corrosion resistance and durability of the coating compared to pure zinc-coated sheets.
- Q: What are the common thicknesses available for steel sheets?
- The common thicknesses available for steel sheets typically range from 0.5 mm to 25 mm, depending on the specific application and industry requirements.
- Q: How do steel sheets perform in cryogenic environments?
- Steel sheets perform well in cryogenic environments due to their low thermal expansion coefficient, high strength, and good ductility. At extremely low temperatures, steel retains its structural integrity, resists cracking or brittleness, and maintains its mechanical properties. This makes steel sheets suitable for various applications in cryogenic industries, such as liquefied natural gas (LNG) storage tanks, aerospace components, and scientific research facilities.
- Q: Can steel sheets be used for industrial machinery parts?
- Yes, steel sheets can be used for industrial machinery parts. Steel sheets are known for their high strength, durability, and versatility, making them suitable for various applications in the industrial sector. They can be easily cut, shaped, and welded to create different components and structures needed for machinery parts. Additionally, steel sheets offer excellent resistance to wear, corrosion, and extreme temperatures, making them a reliable choice for industrial machinery that requires robust and long-lasting components.
- Q: What are the different grades of steel sheets available?
- There are several different grades of steel sheets available, including mild steel, stainless steel, galvanized steel, high-strength low-alloy (HSLA) steel, and carbon steel. Each grade has unique properties and is suitable for various applications in industries such as construction, automotive, and manufacturing.
