FAQ
Q: How does GNEE's HP325 steel plate reduce the scrap rate in cylinder production?
A: By using vacuum degasification and fine-grain control during the melting process, our HP325 steel ensures a uniform structure. This prevents cracking or tearing during the deep drawing process, significantly lowering your factory's rejection rate.
Q: Is the weldability of HP325 steel plates optimized for automated lines?
A: Yes. We keep the carbon equivalent (Ceq) of our HP325 steel low to ensure superior weldability. This makes it perfect for high-speed automated MIG, TIG, and Submerged Arc Welding (SAW) without the risk of cold cracking.
Q: What is the elongation percentage of HP325 steel to ensure safe forming?
A: Our HP325 steel plates for welded LPG cylinders typically feature an elongation (A50mm) of ≥ 22%, providing the necessary ductility for deep drawing the dome halves of gas bottles.
Q: How do you prevent HP325 steel from rusting during long sea voyages?
A: Every shipment is protected with VCI (Volatile Corrosion Inhibitor) paper and waterproof plastic wrapping, secured with steel straps. This ensures the hot-rolled surface of the HP325 remains clean and rust-free upon arrival.
Q: Will HP325 steel crack during the 180-degree cold bend test?
A: No. GNEE's HP325 steel is designed to pass a 180° cold bend test (d=2a) successfully, showcasing its internal soundness and high-quality metallurgical structure.
Q: Can HP325 steel plates handle deep drawing for large 45kg LPG cylinders?
A: Yes, our HP325 grade has the strength and stretchability required for larger cylinders, provided the blanking and hydraulic press parameters are correctly adjusted for the thickness.
Q: Does the surface of HP325 steel require extensive treatment before painting?
A: Our HP325 hot-rolled plates have a very tight and uniform mill scale. A standard shot-blasting process is sufficient to create an ideal surface for powder coating or liquid painting.
Q: How does the silicon content in HP325 affect the manufacturing process?
A: We control silicon levels to ≤ 0.35%, which ensures proper deoxidation of the steel for a cleaner internal structure while maintaining a smooth surface finish.
Q: Can GNEE provide HP325 steel in narrow strips for specific welding lines?
A: Yes, we have in-house slitting facilities to provide HP325 in exact strip widths, helping you reduce material waste and streamline your welding process.
Q: What is the impact of phosphorus and sulfur on HP325 gas cylinder steel?
A: We keep P ≤ 0.025% and S ≤ 0.015%. Lowering these impurities is essential to prevent hot-shortness and ensure the steel remains ductile during high-temperature welding.
