What is the difference between Q345 material and EN steel grade S235J0 plates

EN steel grade S235J0 plates, Q890E steel plate is a kind of quenched and tempered steel plate for high strength structure, in which "Q" means yield, "890" means yield value, "E" means grade level. Q890E steel is equivalent to EN grade S890QL.Executive standard of Q890E steel plate: GB / T 16270.Q890E steel plate delivery status (heat treatment): quenching and tempering.The size, shape, weight and allowable deviation of Q890E steel plate shall comply with GB / T709.

High quality structural steel thick plate product EN steel grade S235J0 plates dimension(mm): 40*2300*12000, 50*1780*7000, 16*2300*12000, 50*2500*10120, 55*1800*11900, 25*2300*12000, 50*2500*10060, 60*2500*8400, 60*2100*10000, 80*1920*6000, 130*2200*10000, 140*2200*10000, 55*1800*11550, 110*2320*8100, 40*1900*7350, 150*2200*10000, 45*2200*9000, 60*2500*8300, 40*2300*12000, 90*2440*12400, 125*1920*5000.

The mechanical properties of hot rolled steel plate are far less than that of cold working and forging, but the EN steel grade S235J0 plates, hot rolled steel plates have better toughness and ductility. Cold rolled steel plate has a certain degree of work hardening and toughness is low, but it can achieve a better yield ratio, and can be used for cold bending spring leaf and other parts. At the same time, because the yield point of cold rolled steel plate is close to the tensile strength, the danger is not foreseen in the use process, and accidents are prone to occur when the load exceeds the allowable load.

At present, there is no obvious release of market demand, the terminal is basically purchased on demand, and the transaction volume is not obvious. However, the current market inventory resources of EN steel grade S235J0 plates are relatively small, business sales pressure is not big, coupled with cost support, so the willingness to stand out is strong. However, after the continuous rise in the early stage, the market's fear of heights has increased, and the operation is still dominated by shipment, and the space for EN steel grade S235J0 plates price rise is limited. Overall, it is expected that EN steel grade S235J0 plates prices will be strong tomorrow.
