For the estimation in April and the second quarter, the estimation on March 16 is still valid, but the decrease in April is 10% higher than the neutral prediction. It is a conservative estimation based on 10% for the high probability event. In the second quarter, the output of overseas pig iron will be reduced by 11.67 million tons, affecting the demand for CCS E40 chemical tanker steel iron ore of about 1.84 million tons; in the first half of the year, the output will be reduced by 18.899 million tons, affecting the demand for iron ore of 32.13 million tons.

Oxygen is a harmful element in CCS E40 chemical tanker steel steel. With the increase of oxygen content, the strength of CCS E40 chemical tanker steel steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of CCS E40 chemical tanker steel steel.
