High strength steel plate Q500D and Q500E steel plate has the same tensile strength above 590 Mpa and yield strength above 500 Mpa.Heat treatment for Q500D steel plate and Q500E steel plate shall be quenched and tempered.The difference between these Q500E steel plate and Q500D steel plate is impact test temperature,Q500E steel plate done at low temperature minus 40 Degree centigrade,however Q500D steel plate done at minus 20 Degree centigrade.Impact test both comply to standard GB/T 229.Nondestructive examination for steel plate Q500D and Q500E steel plate according to standard GB/T 2970.


For our european customers,Xinsteel also supplies S500Q steel plate which is equal to Q500D steel plate,S500QL steel plate which is equal to Q500E steel plate with quenched and tempered.
