Q390B steel material

BBN company has steel plates production workshops and warehouses with a total area of more than 500,000 square meters, and the total inventory of various types of steel exceeds 1 million tons Relying on world-leading processing equipment and storage facilities, the company has strong steel production and processing capabilities, comprehensive logistics and logistics services, ensuring that it can efficiently complete more than 1 million tons of hot rolled plates processing business each year,Q390B steel material.

In order to improve the corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.

Q390B steel material,Q345 and Q345B are steel numbers. The differences are as follows:
1. Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B.
2. Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃).
3. Q345 does not indicate carbon content of steel; Q345B carbon content is 0.20%.
Q345 refers to carbon structural steel with yield point (σ s) of 345MPa. The following letters indicate the quality level, including A, B, C, D and E.
