Export hot rolled equivalent grades of raex 500 with quenching

BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of equivalent grades of raex 500 steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main equivalent grades of raex 500 production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

Oxygen is a harmful element in equivalent grades of raex 500 steel. With the increase of oxygen content, the strength of equivalent grades of raex 500 steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of equivalent grades of raex 500 steel.

Affected by the weakening of the futures steel market, the market sentiment is cautious. Considering the resource cost, the equivalent grades of raex 500 merchants have strong willingness to stand up price and follow the rise. After the price rise, the equivalent grades of raex 500 merchants' shipment is not smooth, the transaction situation is generally weak, the downstream high level acceptance is weak, and the inventory pressure is not obvious. It is expected that the equivalent grades of raex 500 prices will fall down and adjust in the future.

Peritectic reaction often occurs in the process of cooling and solidification of wear-resistant steel plate, equivalent grades of raex 500, and accompanied by this reaction, there will be greater volume change and linear shrinkage, which is mainly due to the hot cracking of continuous casting slab in the casting process. In the mold, the heat load transmitted from the billet is too much or uneven around the meniscus of molten steel, resulting in uneven heating, which is more likely to produce longitudinal cracks.
