Five causes of cracks in Q295NH weathering steel GB/T 4171 plate during quenching

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 weathering steel GB/T 4171 plate 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 weathering steel GB/T 4171 plate customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

Corrosion resistant steel prices are generally higher. What are the applications of Q295NH weathering steel GB/T 4171 plate, corrosion resistant steel? First, the corrosion resistant steel can be used in chemical containers, such as furnaces. Some chemical products have strong corrosivity and need steel with excellent corrosion resistance, otherwise they will be easily corroded. Second, the corrosion resistant steel can be used for sewage pipelines. Industrial sewage pipelines need to discharge a large amount of wastewater, which may contain harmful substances.
