Q345qC steel plate is the steel plate of bridge structure, the implementation standard is GB / T 714-2015 standard. NV B cargo ship steel, Q345qC-Z25 steel: Q represents the yield strength, 345 represents the small yield strength, the unit is MPa, q is short for the bridge, C quality grade, corresponding to the corresponding impact temperature and impact work value, Z is the Z-direction performance that is the performance of the steel plate thickness direction, Z25 is the Z-direction Performance level requirements.
The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel NV B cargo ship steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the NV B cargo ship steel market and has strong competitiveness.
Plasma cutting has a wide range of applications. With different working gas, it can cut various kinds of metals that are difficulty to handle by oxygen cutting. Plasma cutting is fast and efficient when cutting metal with small thickness. The NV B cargo ship steel cutting speed can reach more than 10m/min. Plasma cutting can get a clean, neat, non stick slag cutting surface, while the deformation and thermal effect of the incision are small, its hardness change is little, and the cutting quality is good.
NV B cargo ship steel, Weathering steel plate is a kind of common steel plate. For ordinary steel plate, if it is used for a long time, it will contaminate the steel surface with a layer of rust, which will seriously affect the normal use of steel. Although the weathering steel plate will produce rust, this layer of corrosion is like a layer of dense oxide film, which is firmly attached to the steel surface to prevent the further corrosion of the base and steel. There are many weathering steel plate manufacturers will adopt some corrosion treatment methods.
Both parties shall confirm the NV B cargo ship steel material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the NV B cargo ship steel steel plant.
