Rolled sheet is a very common material in industrial construction. Rolled sheet at room temperature is cold-rolled sheet, and cold-rolled sheet is the rolling of hot-rolled coils below the recrystallization temperature. The hot-rolled sheet is rolled above the recrystallization temperature. So what is the difference between 5mm A633 Grade D steel, hot rolled sheet and cold rolled sheet?

5mm A633 Grade D steel and Q690CF plate are hot rolled steel plates. The chemical composition of Q690CF steel is as follows: C: 0.05-0.08%, Si: 0.22-0.30%, Mn: 1.6-2.0%, Al: 0.2-0.35%, Cr: 0.10-0.35%, Mo: 0.20-0.35%, Ni: 0.1-0.4%, Cu: 0.15-0.3%, Nb: 0.025-0.045%, V: 0.01-0.03%, Ti: 0.005-0.03%, P ≤ 0.010%, S ≤ 0.008% by mass percentage, the remaining is Fe and unavoidable impurities.

This week, the output of 5mm A633 Grade D steel increased slightly, while the total inventory changed from decrease to increase, indicating that the apparent consumption of 5mm A633 Grade D steel decreased again. At present, due to the current demand release is not as expected, while the 5mm A633 Grade D steel production and inventory are still at a relatively high level, the market wait-and-see sentiment is strong. To sum up, it is expected that 5mm A633 Grade D steel prices will continue to narrow consolidation in the short term.
