Q690D steel belongs to high-strength welded structural steel. Among them, Q represents the yield strength, 690 represents the yield strength value, and D represents the grade of the steel plate. The quality grades of common Q690 series steel are A, B, C, D, E. The impact of grade D steel plate is -20°C. Q690D steel can be called a low temperature resistant high strength steel with a yield strength of 690Mpa.

The difference between sale the 09CUPCRNI-B, hot rolled sheet and cold rolled sheet: hot rolled sheet has low hardness, easy processing and good ductility. The cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The cold rolled sheet is mostly used in automobile manufacturing and electrical products. Therefore, the two have their own characteristics. According to these characteristics, it is more appropriate to choose the right rolled plate to maximize its effect and benefit.

As to the Chemical composition, the different content is a main on carbon content, while the carbon content of sale the 09CUPCRNI-B, A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 Grade D is 230MPa (33 ksi).

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
