Q690E carbon steel plate sheet saw cutting plate

ASTM A441, used in low-tolerance, state-of-the-art structures, such as towers and large telescopes, Q690E carbon steel plate sheet is a high-strength structural grade with a yield strength of 40,000 to 50,000 psi and an allowable bending stress of 24,000 to 30,000 psi.

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, Q690E 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.

ArcelorMittal said it was taking measures to cut its North American Q690E carbon steel plate sheet steel production in response to the weakening demand for downstream steel after the outbreak of covid-19, foreign media reported. It is reported that ArcelorMittal's plant in the port of Indiana is ready to shut down the No. 4 blast furnace.
