1.What is S890Q equivalent to?
S890Q is a European high-yield strength structural steel (EN 10025-6) with a minimum yield strength of 890 MPa, equivalent to the Chinese grade Q890, and is often compared to American grades like ASTM A514 or comparable Japanese standards (JIS G3106 SM570 for similar use), used for heavy-duty applications like cranes, bridges, and mining equipment requiring excellent weldability and strength after quenching and tempering.
2.What is S890QL material equivalent?
S890QL is a European (EN 10025-6) high-strength quenched and tempered structural steel, with equivalents including TStE 890 V, SSAB's Strenx 900 E/F, and Dillinger's DILLIMAX 890, offering a minimum yield strength of 890 MPa, good weldability, and toughness for demanding applications like heavy machinery and construction. Key equivalents often focus on similar yield strength (around 900 MPa or 130 ksi) and processing, though exact chemical compositions and impact toughness temperatures might vary slightly by standard.
