Low price A709 grade 50 carbon steel plate sheet

The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. If they are long, they need to remove the redundant parts, that is, cut them out. Their length A709 grade 50 carbon steel plate sheet is suitable for the length required by the construction of steel pipes.

A709 grade 50 carbon steel plate sheet, Q345B low alloy steel plate composition: 1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%; 2) Add manganese-based alloying elements; 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel; In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.
