Q295NH railway steel Thick Plate Supply

Marine steel is widely used in all kinds of ships and offshore platforms, but it also puts forward higher and higher requirements for marine steel. In general, the demand share of Q295NH railway steel high-strength marine steel continues to increase. In terms of strength requirements, with the change of ship's large-scale, safety and coating specifications, the general trend is that the consumption of ordinary strength grade A marine steel plate is gradually reduced, and the consumption of high-strength marine steel plates is increased.

Over the years, the company has established a standard of Q295NH railway steel steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to Q295NH railway steel quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.

During the construction of hot-dip Q295NH railway steel galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatment (zinc rich paint) shall be done timely after the welding is completed. It is feasible in the construction process of open and closed air conditioning system, which can improve the Q295NH railway steel construction speed and the firmness of the pipe connection. Therefore, the hot-dip galvanized pipe can be welded and connected under the construction conditions and on the premise of relevant protection and anti-corrosion measures.

The alloying principle of low alloy high strength steel plate mainly uses solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements to improve the strength of low alloy high strength steel plate, Q295NH railway steel. At the same time, the effect of fine grain strengthening on the reduction of ductile brittle transition temperature of low alloy high strength steel platel is used to offset the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that low alloy high strength steel plate can obtain high strength while maintaining good low temperature performance.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
