A709 grade 50 carbon steel plate sheet price went up and down

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of A709 grade 50 carbon steel plate sheet nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of A709 grade 50 carbon steel plate sheet steel, can be used as an alloying element of low alloy steel.

A709 grade 50 carbon steel plate sheet, 45# steel is carbon steel, belonging to high strength medium carbon quenched and tempered steel, with carbon content of 0.45%, so it is called 45# steel. 45# steel does not contain specially included alloy elements. A709 grade 50 carbon steel plate sheet, 45# steel is one of the most widely used high-quality structural steel. 45# steel is suitable for manufacturing high strength moving parts, such as air compressor, piston of pump, impeller of steam turbine, rolling shaft, connecting rod, worm, rack, gear and pin in heavy and general machinery.

Its responsibilities: make customs clearance documents, track products production process, and update shipping information for customers. The company will adhere to the mission of reflecting social values, take the scientific management system as the guarantee of daily operations, and provide continuous technological innovation to support its sustainable development.

Strip steel is mainly used for the manufacture of welded pipes, clamps, washers, spring blades, saw blades, blades and other fields, so the A709 grade 50 carbon steel plate sheet, strip steel specifications are also relatively standardized. First, the strip width should be within 1300mm, if it is too wide, it will become a steel plate, and the machining is not allowed to be too wide, otherwise it will fail. Second, the strip steel length is not limited, and the strip steel can be coiled together after bending, reducing most of the space.
