2365 Tons Q690C carbon steel plate sheet shipped to Chile 2018

Delivery status: Hot-rolled Q690C carbon steel plate sheet steel In the hot-rolled state or controlled rolling state or heat treatment, the state of delivery, cold-rolled steel to the annealing state of delivery.

45# seamless pipe belongs to high quality carbon structural steel. The carbon (C) content of No.45 seamless pipe is 0.42 ~ 0.50%, Si content is 0.17 ~ 0.37%, Mn content is 0.50 ~ 0.80%, Cr content is ≤ 0.25%, Ni content is ≤ 0.30%, Cu content is ≤ 0.25%. The tensile strength, yield strength, elongation, reduction of area and impact energy of 45# seamless pipe are 600 MPa, 355 MPa, 16% and 40% respectively. 45# seamless pipe is used to manufacture high strength moving parts.

Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, Q690C carbon steel plate sheet included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.

The advantages of flame cutting are simple cutting and low cost. The disadvantage of flame cutting is that when cutting thin plates, cutting deformation problems are prone to occur, and the materials that can be cut have certain limitations. The advantage of CNC cutting is that it can cut Q690C carbon steel plate sheet and any complex parts with high cutting accuracy. The disadvantage of CNC cutting is that there are certain operational and technical requirements.
