Stimulated by the positive macro news, today's q235b hot rolled steel sheets futures trend fluctuated upwards, driving up spot prices. On the whole, the cost side is high, the inventory pressure is not great, and q235b hot rolled steel sheets traders are cautiously optimistic. Although the short-term demand continuity still needs to be considered, the overall price bottom is supported. It is expected that the q235b hot rolled steel sheets price may fluctuate at a high level tomorrow.

There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products q235b hot rolled steel sheets are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.

Alloying elements, especially Mn, Ni, Cr, Mo and B (trace elements), can increase the hardenability of the q235b hot rolled steel sheets steel, so as to obtain a deeper hardened layer and adopt a slower quenching cooling rate. Alloying elements, especially Si, Mo, V and W, improve the tempering stability of the q235b hot rolled steel sheets steel to slow down the tempering softening effect. When the content of W, Mo and V is high, secondary hardening will occur during quenching and tempering, so as to improve the hot hardness of the steel.
