S890QL1 STEEL PLATE,EN10025-6 S890QL1
Source:Yusheng steel
High strength steel plate and sheet S890QL1 under EN 10025_6 shall be under Quenched and Tempered delivery
condition when rolling.The number QL1 stand for doing low temperature impacting test at minus 60 centi degree at
minimum 27 J energy on transverse direction V_notch test pieces.
Owning to the higher tensile strength&yield strength and so lower temperature impacting test,so our enigeers foucs
on the rolling process carefully and limited the chemical composition step by step,then roll these plates in a higher
steel quality and a higher percentage of passing rate.Every plate have to be done mill test in mill’s lab before taking
out mill,it can guarantee steel property for each plate and would issue the original MTC for all the passing plates
along with the materials.
