S620QL low alloy structural steel
S620QL high strength steel belongs to tempered high yield strength structural steel, which implements European standard EN10025-6.In S620QL high tensile steel, S means structural steel, 620 is the yield value in MPa, and QL means that the impact temperature of the steel plate is -50°C.
The S460Q high strength alloy steel we offer is produced strictly according to the standard, passed the quality certification, we can provide the quality certificate, if you have special requirements, we can accept third party testing.
