S890Q STEEL PLATE,EN10025-6 S890Q
Source:Yusheng steel
High strength steel plate S890Q mainly be used high pressure situiations,and can bear heavy bend when
construction.All these steel plates and sheets S890Q have to be done Quenched and Tempered heat treatment.
Steel grade Q890D in Chinese GB standard is equal to S890Q steel.They have the same yield strength at
minimum 890 Mpa,and both shall be done low temperature impacting test at minus 20 centi degree.
Comparing with the other two similar steel grades S890QL1 and S890QL,S890Q may has a leisure limited on
chemical P And S.Please find the values of contains of each main chemical composition as below table:
