The market demand of weather resistant Q295NH steel is still tight

The production process of seamless steel pipe for high pressure boiler is more strict than that of weather resistant Q295NH steel ordinary steel pipe. In the process of using seamless steel pipe for high pressure boiler, oxidation and corrosion will occur under the action of high temperature flue gas and steam. Therefore, the requirements for the durability and anti-oxidation corrosion performance of seamless steel pipes for high-pressure boilers are higher, and has requirements for good structural stability.

Alloy steel plate is a kind of high strength steel plate, which has good wear resistance. It is suitable for road laying, factory floor and other fields with high wear resistance requirements. The performance of the weather resistant Q295NH steel, alloy steel plate is more prominent. The alloy steel plate has good high temperature resistance and low temperature resistance, which will not cause material deformation in any high temperature and low temperature environment. The strength retention of alloy steel plate is better, and the material stability is better.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than weather resistant Q295NH steel. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel weather resistant Q295NH steel is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
