The theoretical weight of seamless steel pipe is the weight per meter of steel pipe calculated by the calculation formula: meter weight = (outer diameter - wall thickness) * wall thickness * 0.02466, in which the outer diameter refers to the farthest distance between the outer walls on both sides of the steel pipe, and the wall thickness is the thickness of the seamless steel pipe wall. The weight per meter of corten b standard steel seamless steel pipe is calculated by the formula. If you want to get the weight of the whole seamless steel pipe, you should multiply the actual length of the steel pipe.

The effect of nitrogen (N) on the properties of corten b standard steel 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 corten b standard steel and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

According to the data released by the world iron and Steel Association, the world pig iron production in March 2020 was 103 million tons, a year-on-year decrease of 3.5%, a year-on-year increase of 1.8% in February, and the overseas pig iron corten b standard steel production excluding China was 36.309 million tons, a year-on-year decrease of 11%.
