What is price of NM400 use for bridge in China

During the steel plate cutting, the special-shaped steel plate cutting process is often carried out. In this operation process, some cutting curves will be generated. Therefore, there should be relatively high precision standards during the processing of NM400 use for bridge. The operators need to have rich experience, and they also need to be proficient in the operation methods and working skills of the equipment, so as to ensure that the steel plate can meet the shape requirements after processing.

NM400 use for bridge product plate specification range: Thickness 3-150mm Width 1500-4020mm Length 4000mm-17000mm Heat treatment: annealing, or normalizing and tempering

The main problem of safety education in iron and steel enterprises is not that the company does not pay attention to it and does not implement it, but that the subordinate units do not strictly follow the company's requirements. In order to avoid the problem of safety education becoming a mere formality, BBN steel company improved the safety education model from the following aspects: First, the content of safety education should not only pay attention to the accumulation of safety knowledge, but also pay attention to the mastery of safety operation skills.

Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for NM400 use for bridge and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
