S620Q STEEL PLATE,EN10025-6 S620Q
Source:Yusheng steel
Comparing with S620QL1 and S620QL,steel plate S620Q has more contains of chemical elements P and S in
Ladle analysis,else the low temperature of impacting test for S620Q steel plate and sheets should be done
under minus 20 centi degree.For these three steel grades S620QL1,S620QL,S620Q shall be under Quenched
and Tempered delivery condition.
About our Mill Test Certificate format,we can offer customers according to EN 10204 3.1B and EN 10204 3.2.For
the 3.2 format,customers should inform us which third party do they need to do inspect before order to us.After
inspection,we would like to submit customers the inspection reporter issued by the third party along with our MILL
TEST CERTIFICATES together.Now we list the technical table for steel S620Q as belows:
