Product Description:

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: What are the different jointing methods for steel sheets?: Steel sheets can be joined using various methods, depending on specific requirements and applications. Common jointing methods for steel sheets include welding, bolting, riveting, adhesive bonding, and mechanical fasteners. Welding is widely used, involving melting the steel sheet edges and joining them by applying heat and pressure. Different welding techniques, like arc welding, gas welding, or laser welding, can be used depending on the steel sheet thickness and type. Bolting involves using bolts and nuts to join steel sheets together. This method is suitable for easily disassembling or replacing joints and can be used for both permanent and temporary connections. Riveting is another method, using rivets to join steel sheets. Rivets are cylindrical metal pins inserted through holes in the sheets and deformed to secure the joint. Riveting is ideal for applications requiring high shear strength. Adhesive bonding uses specialized adhesives to join steel sheets. This method provides a strong and durable joint, suitable when welding or other mechanical jointing methods are not suitable. Adhesive bonding also distributes stress more uniformly across the joint. Mechanical fasteners, like clips, clamps, or brackets, can be used to join steel sheets. These fasteners offer a secure and reliable connection without requiring welding or other permanent jointing methods. They are commonly used when ease of assembly and disassembly is necessary. In conclusion, the choice of jointing method for steel sheets depends on factors such as the application, desired strength and durability, and ease of assembly and disassembly. Careful consideration of these factors is essential to ensure a successful and reliable connection.
