Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the Q295NH railway steel hot rolled coil project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of Q295NH railway steel hot rolled coil customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
Compared with Q295NH railway steel hot rolled coil, pressure vessel and boiler steel plates have such advantages: The pressure vessel and boiler steel should be pure, and the fracture structure of the boiler steel plate should be uniform without cracks and inclusions. Besides, the strain aging sensitivity is small, and the strain aging impact value of the pressure vessel and boiler steel plate is required to be no less than 50% of the non-aging impact value. That is why pressure vessel and boiler steel plate is first choice for fabricating pressure vessels and boilers, while Q295NH railway steel hot rolled coil is not.
Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous Q295NH railway steel hot rolled coil process between continuous casting and rolling mills, continuous casting slabs hot transfer hot charging, increased direct rolling, and continuous cold rolling processes. The development of controlled rolling and controlled cooling technology that combines rolling and heat treatment has played a huge role in improving the properties of rolled materials.
In December, 2018, our Vietnam customer purchased 352 tons SA387Gr12Cl2 and SA387Gr11Cl2 Q295NH railway steel hot rolled coil steel plates for their tank fabrication project. The customer need those cargo urgently, and we keep many stock in warehouse , it only takes about 3days we collect total cargo for shipping to customer. The customer are very appreciate our quality and service. They Q295NH railway steel hot rolled coil become our regular customer and repeat order to us every month.
