s355j2w+n equivalent flat bar

Carbon structural steel refers to the kind of steel which is mainly used in construction and engineering structures without adding alloy elements. Among all kinds of steel, s355j2w+n equivalent, carbon structural steel has a large output, the most extensive use and low price. Carbon structural steel is often rolled into various steel bars (round steel, square steel, flat steel, hexagonal angle steel, etc.), section steel (I-beam, angle steel, channel steel, L-shaped steel, etc.), profiled steel and steel plate. Carbon structural steel is mainly used in buildings and engineering structures such as workshops, bridges, ships, etc. Generally, heat treatment is not required for carbon structural steel.

The tensile strength of seamless steel pipe is more than 8-10 times of that of ordinary steel, and its elastic modulus is better than that of steel, with excellent creep resistance, corrosion resistance and seismic resistance; the mechanical performance of seamless steel pipe is excellent, easy to machine, etc.; the seamless steel pipe s355j2w+n equivalent is highly elastic, reused in mechanical equipment, memoryless, deformation free, and antistatic.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the s355j2w+n equivalent steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of s355j2w+n equivalent seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
