S690Q STEEL PLATE,EN10025-6 S690Q
Source:Yusheng steel
Under the European standard EN10025_6,steel grade S690Q belongs high yield strength structural steels in the
quenched and tempered condition.Besides the necessary impacting test,Ultrasonic test for S690Q steel plate is a
n additional technical terms,it should be tested according to ASTM A578/A578M,A588/A588M or A435/A435M.
Comparing with the steel grades S690QL and S690QL1,S690Q has a more leisure limited on the chemical
elements P and S.Maximum P% is 0.025,Maximum S% is 0.015.For other main alloy elements they are the same
limited.Now we list the details of S690Q analysis in Chemical composition and mechanical property as belows:
