What is the chemical composition of Q500 steel?
Q500 steel plate is a low-alloy high-strength structural steel. It mainly has three grades: C, D, and E, which are divided into Q500C, Q500D, and Q500E. GB/T 16270-2009 Q500D High strength structural steel plates in the quenched and tempered condition. GB/T 16270 Q500 steel equivalent: ISO: HS490-D, DIN: S500MC (1.0984), NF: S500MC.Q500 steel plate material standard: GB/T 1591—2008
Chemical composition of Q500 steel plate:
C:<=0.18 Mn:<=1.80 Si:<=0.60, P:<=0.030 S:<=0.030 Nb:<=0.11,V:<=0.12 Ti:<=0.20 Cr:<=0.60, Ni: <=0.80 Cu:<=0.55 N:<=0.015, Mo:<=0.20 B:<=0.004 Al:<=0.015
Q500 steel is a series of high strength, high tenacity, excellentwelding performance use of steel structure. It has been widely used in general building and all kinds of engineering machinery, such as mining and all kinds of engineering construction, excavator.
