The acicular ferrite pipeline steel can inhibit the formation of polygonal ferrite, promote the acicular ferrite transformation, and improve the precipitation strengthening effect of carbon and niobium nitride by adding molybdenum to reduce the transformation temperature of polygonal ferrite, so as to improve the strength of steel and reduce the ductile brittle transition temperature. The JIS carbon steel SM490A CS plate, tempered sorbite pipeline steel adopts the heat treatment process of quenching and tempering. The tempered sorbite structure is formed to meet the comprehensive requirements of thick wall, high strength and sufficient toughness.

Pakistan's iron and steel industry has suspended JIS carbon steel SM490A CS plate production and operation since the outbreak, the dawn reported on April 8. Last month, Prime Minister Imran announced a rescue package for the steel industry. Recently, Pakistan's steel industry called for the resumption of production as soon as possible. The Secretary General of the association of large JIS carbon steel SM490A CS plate steel producers in Pakistan said that steel is the pillar of Pakistan's construction industry, and Pakistan's economy cannot bear the consequences of the long-term closure of the steel industry. Any delay in the resumption of production will lead to the failure of the government's plan to revitalize the construction industry, which will have a negative impact on Pakistan's economy. It is hoped that the government will immediately resume JIS carbon steel SM490A CS plate production in the steel industry, especially those that are able to provide shelter for workers.

Recently, the price of JIS carbon steel SM490A CS plate raw materials has been strong, the mainstream steel mills have raised the price, and the cost of taking goods by JIS carbon steel SM490A CS plate merchants has risen. In addition, macro capital will still have a disturbance to the market, and the current wait-and-see sentiment of downstream and middlemen is strong. On the whole, the steel market is intertwined with many spaces, and the supply and demand fundamentals are generally in a weak balance pattern. High inventory suppresses the price of JIS carbon steel SM490A CS plate steel, and high cost supports the price of JIS carbon steel SM490A CS plate steel, while macro capital also disturbs the market from time to time. In the short term, the market wait-and-see sentiment is strong, JIS carbon steel SM490A CS plate steel prices or continue to fluctuate, the range of rise and fall are limited.
