What is the meaning of S890QL grade and its applicable standard?
It's an EN10025-6 structural steel. "S"=structural steel, "890"=890MPa yield strength, "Q"=quenched-tempered, "L"=low-temperature toughness.
What are the key chemical and mechanical property indicators of S890QL?
C≤0.19%, P≤0.020%, S≤0.010%; ReH≥890MPa, Rm=940-1100MPa, -40℃ impact energy ≥30J.
What are the requirements for delivery condition and surface quality of S890QL?
Delivered quenched-tempered; no harmful defects like cracks. Special requirements need to be specified in the contract.
What processing methods suit S890QL and what precautions should be taken?
Flame/plasma/laser cutting available; preheat before welding, control cold bending radius, stress relief annealing optional.
In which fields is S890QL mainly applied?
It's widely used in heavy machinery, bridge construction, oil derricks, port cranes and mining equipment under harsh conditions.
What is the core difference between S890QL and S890Q?
S890QL has "L" for low-temperature toughness (-40℃), while S890Q only meets 0℃/-20℃ impact requirements.
