As an experienced world class steel materials supplier and exporter, logistics and fast delivery is a crucial step to us. Our logistics department and shipping department take the responsiblity to allocate and transport steel materials from our mill and warehouse to customer port or designated destination. The cooperation of the two departemts are excellent and that powerfully support our fast delivery, and strive for shorter time for customers to receive steel materials.
Q295NH railway steel hot rolled coil, low alloy high strength steel has good weldability. Welding is the most common method to construct engineering structure, so the steel used in engineering structure requires good welding performance. Low alloy high strength steel has low carbon content, low alloy element content and good plasticity, so it is not easy to produce quenching structure and crack in the weld area, and the addition of Ti, Nb, V can also inhibit the grain growth in the weld area. Therefore, most of the low alloy high strength steels have excellent welding performance and no heat treatment is required after welding.
In actual processing applications, the processing Q295NH railway steel hot rolled coil thickness of flame cutting ranges from 6 to 200 mm, and the Q295NH railway steel hot rolled coil cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting Q295NH railway steel hot rolled coil with a certain thickness above 10mm.
In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate Q295NH railway steel hot rolled coil for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 Q295NH railway steel hot rolled coil and priming gray oxide primer, and arrange shipment in time. Meet the customer urgent delivery request.
