Weldability of Q235B carbon steel plate sheet

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with Q235B carbon steel plate sheet ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.

According to a report by yonhap news agency on April 26, under the impact of COVID - 19 epidemic, the steel industry chain was also affected. Hyundai lost 29.7 billion won. According to the report, the automobile and other downstream steel industry production stoppage directly led to a precipita-like decline in steel demand, is the main reason for the decline in steel enterprise performance of the main reason for hyundai said, hyundai kia motor production extension, by the end of April is expected to reduce production of 500,000 vehicles, as a result, Q235B carbon steel plate sheet, automotive steel demand will be reduced by 300,000 tons.
