1What is S890QL1 material?
S890QL1 is a European standard (EN 10025-6) high-strength, low-alloy (HSLA) structural steel known for exceptional strength and toughness, achieved through quenching and tempering. Its name signifies a minimum yield strength of 890 MPa (S890), good toughness at low temperatures (QL), and specifically excellent impact energy absorption down to -60°C (QL1). It's used in heavy machinery, construction, and offshore structures where high performance in demanding conditions is critical.
2what is s890ql1 equivalent to ?
S890QL1 is a European high-yield strength structural steel (EN 10025-6 standard) known for excellent toughness at low temperatures (down to -60°C) and good weldability, with equivalents including Strenx® 900 F (SSAB), DILLIMAX 890 E, and generally comparable grades like ASTM A514 (though A514 has lower yield strength) and Chinese grades such as Q890. Its designation means S=Structural, 890=890 MPa yield strength, Q=Quenched & Tempered, L1=Impact tested at -60°C.
3What are Common Testing Requirements for s890ql1 ?
Common testing requirements for S890QL1 steel, a high-strength quenched & tempered steel, focus on mechanical properties (tensile strength, yield strength, elongation) and impact toughness (Charpy V-notch), typically at lower temperatures like -60°C for S890QL1, alongside detailed chemical composition analysis (Carbon, Silicon, Manganese, etc.) to ensure compliance with EN 10025-6 standards, with testing frequency often tied to heat/cast and tonnage.
4Is S890QL1 carbon steel?
Yes, S890QL1 is a type of high-strength, low-alloy carbon steel, specifically a quenched and tempered (Q+T) structural steel (S-grade) known for high yield strength (890 MPa) and excellent toughness, made possible by controlled alloying and heat treatment for demanding applications like heavy construction and mining.
5Is S890QL1 high speed steel?
No, S890QL1 is not high speed steel (HSS); it's a high-strength quenched and tempered structural steel (HSLA), known for its excellent toughness, weldability, and yield strength (around 890 MPa), used in heavy construction, machinery, and cranes, whereas HSS is a tool steel for cutting tools.
