The yield strength of A40, D40, E40 and F40 A588 grade A heavy plate is not less than 390N/mm^2, and the tensile strength is 510~660N/mm^2. A, D, E and F respectively indicate that they can be at 0° and -20 ° respectively. Impact toughness A588 grade A heavy plate that can be achieved at -40℃, -60℃.
Hyundai Steel Co. has no plans to cut production further despite weak steel demand due to the coronavirus pandemic, the company's president said. Earlier this year, South Korea's second largest steelmaker reduced its A588 grade A heavy plate annual production of hot rolled coils from 1 million tons previously to 700 thousand tons per year for EAFs. A turnaround is expected after the third quarter of this year.
A588 grade A heavy plate, Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.
Lopes, President of the Brazilian Iron and Steel Association, pointed out that at present, increasing A588 grade A heavy plate and so on steel exports would be the best choice for Brazilian steel producers. The Association has made a series of proposals to the Brazilian government to support the economic recovery. Lopes revealed that the Association is seeking to increase the export tax rebate proportion of the steel industry from the current 0.1% to 5%, which will give related products a price advantage of 7% when exporting, and the export volume is expected to increase by 20%.
