Characteristics of carbon steel sheet, Q1150 and S1150Q steel plates: 1. High purity steel: the contents of inclusions P, S and H, O, N in steel are strictly controlled. 2. Ideal strength reserve: the yield strength and tensile strength are moderately controlled, and the surplus is usually 50-80MPa. 3. Reasonable yield ratio control: by adjusting the composition and improving the process, the yield ratio is more reasonable.
The effect of nitrogen (N) on the properties of carbon steel sheet 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 carbon steel sheet and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
On 18th December, 2019, BBN Group decorated the office carbon steel sheet building with many kinds of pendant. There were christmas trees, gifts and snowflakes in the logo wall. At the same time, we made a video at the Zhengzhou office to celebrate the coming Christmas holiday. Our carbon steel sheet oversea sales team and market delevopment team wish you Merry Christmas and Happy New Year. Besides, we prepare some meaningful gifts for our old customers.
