How to effectively prevent the hot rolled 09CuPCrNi-B from welding cracks and deformation

ASME hot rolled 09CUPCRNI-B delivery status: thickness ≤40, hot rolled or normalized; thickness ＞40, normalizedAccording to the different tensile strength of the material, ASME SA204 steel is divided into three strength grades: A, B, and C, namely SA204GrA, SA204GrB, and SA204GrC. The maximum thickness of steel plates corresponding to these three grades is limited to:SA-204A large plate thickness does not exceed 150mmSA-204B large plate thickness does not exceed 150mmSA-204C large plate thickness does not exceed 100mm

Q235 steel grades cover Q235A, Q235B, Q235C and Q235D. Other than Q235A, the other three Q235 steel grades needs impact test. Charpy V-notch specimen is used for impact toughness test. The impact toughness index is Akv. Q235 steel plates are widely used because of its moderate carbon content, good comprehensive performance, good coordination of strength, plasticity and welding performance.

S355J2 steel plate hot rolled 09CUPCRNI-B rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the hot rolled 09CUPCRNI-B single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
