S690QL STEEL PLATE,EN10025-6 S690QL
Source:Yusheng steel
Quenched and tempered heat treatment steel plate and sheet S690QL under EN 10025_6 standard is equal to the
steel grade Q690E in Chinese GB standard. Both these two steels shall be done low temperature Charpy_V
impacting test at minus 40 centi degree.At present,the maximum thickness for S690QL for our mill is till 200
millimeter.If your needed thickness above 200mm,we have to submit this inquiry to our technical department for
reviewing and make a trial rolling.
After rolling all the plates,the mill would issue original Mill Test Certificate for each plate which would draft all the test
values about chemical composition,mechincal properity,impacting test,heat treatment and so on.Else,the Heat
Number and Batch Number is necessary for tracking for the true steel plates.
