The excellent processing performance of Q960 quenched and tempered steel: ASTM A709 carbon steel plate, Q960 steel plate can be used for cold processing, bending processing and cutting processing. When gas cutting, cracks will not occur even if it is not preheated. When preheating processing, Q960 QT steel needs to be processed below the tempering temperature. Superb wear and corrosion resistance: As Q960 steel contains alloying elements such as copper and chromium, it has good corrosion resistance, higher hardness, and good wear resistance compared with ordinary steel.
The effect of nitrogen (N) on the properties of ASTM A709 carbon steel plate and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in ASTM A709 carbon steel plate and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
Delivery status: Hot-rolled ASTM A709 carbon steel plate steel In the hot-rolled state or controlled rolling state or heat treatment, the state of delivery, cold-rolled steel to the annealing state of delivery.
The market mentality tended to be cautious, and the market prices in most regions were adjusted in a narrow range. In terms of resources, the current market inventory continues to digest, but due to the high output of ASTM A709 carbon steel plate, and the off-season effect of downstream demand is still continuing, resulting in a slow de stocking speed. In the short term, in the case of poor shipment of high price resources and cautious market mentality, it is expected that the price of ASTM A709 carbon steel plate in the short term may be in weak consolidation operation.
