The company now has 5mm A633 Grade D steel oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than 5mm A633 Grade D steel 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.
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.
