What should be paid attention to when using ABS DH36 bulk cargo vessels steel

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of ABS DH36 bulk cargo vessels steel nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of ABS DH36 bulk cargo vessels steel steel, can be used as an alloying element of low alloy steel.

The grades specified in the GB712-2011 ship and marine engineering structural steel standard are: Grade A, B, D, E, AH32, DH32, EH32, FH32, AH36, DH36, EH36, FH36, AH40, DH40, EH40, FH40, AH420, ABS DH36 bulk cargo vessels steel, DH420, EH420, FH420, AH460, DH460, EH460, FH460, AH500, DH500, EH500, FH500, AH550, DH550, EH550, FH550, AH620, DH620, EH620, FH620, AH690, DH690, EH690, FH690.

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 ABS DH36 bulk cargo vessels 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.

It is reported that during the period from the end of 2018 to the first quarter of 2019, some Japanese long process steel mills encountered a series of production line equipment failures, resulting in the overall output decline. Japanese ABS DH36 bulk cargo vessels steel steel mills must give priority to domestic customers, so the export volume in the first half of last year was relatively small. Meanwhile, in the first half of the year, Japan's imports of general ABS DH36 bulk cargo vessels steel steel were about 2.079 million tons, down 16.4% year-on-year; imports of special steel were about 332000 tons, down 14.2% year-on-year.
