The price of 09cuptire-a steel grade in northwest Europe is uncertain

The advantages of 09CUPTIRE-A steel grade, seamless steel pipe are high pressure resistance, good toughness, long pipe section and few joints. It is widely used and the rolling technology of domestic steel mills is also very mature. Compared with round steel, the weight of seamless steel pipe is lighter under the same strength. Seamless steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, save materials and processing time. Compared with the welded pipe, there is no weld on the outer surface of seamless steel pipe, and it has good compression resistance.

Lopes, President of the Brazilian Iron and Steel Association, pointed out that at present, increasing 09CUPTIRE-A steel grade 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%.

The effect of nitrogen (N) on the properties of 09CUPTIRE-A steel grade 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 09CUPTIRE-A steel grade and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

Q345qCNH grade is a weather-resistant structural steel for bridges. Bridge steel grade is Q345qC. It is produced by the standard GB / T714-2014. Weather-resistant bridge plate Q345qCNH is a kind of structural steel plate for bridge. Add a certain amount of alloy elements, such as P, Cr, Ni, Cu, Mo, etc. to the steel to form a protective layer on the surface of the metal substrate to improve the atmospheric resistance corrosive steel.
