Q690C steel plate is a high-strength steel plate. Q690C steel plate belongs to structural steel. Q is the yield strength, 690 is its minimum yield value, and C is its grade. Q690C steel plate has higher yield strength and tensile strength. Corresponding grades include Q690C steel plate, Q690D steel plate, Q690E steel plate, Q690F steel plate, etc., which have the same attributes but different grades.
The implementation standard of Q690C steel plate: implement the GB/T16270-2009 standard.
Q690C steel plate is a low-alloy high-strength structural steel used in buildings, bridges, ships, vehicles, pressure vessels and other structures. The carbon content (smelting analysis) of low-alloy high-strength structural steel is generally not more than 0.20%, the total content of alloy elements is generally not more than 2.5%, and the yield strength is not less than 295MPa. It has good impact toughness and welding performance.
