S690QL Siab zog hlau
High Strength Low Alloy Product Description
S690QL siab tensile steel yog ib qho kev ua tau zoo ntawm cov qauv hlau ua raws li EN 10025-6 tus qauv. S690QL siab zog steel muaj lub zog siab, toughness, hnav tsis kam thiab weldability.
S690QL siab zog ntawv hlau Khoom npe: S - Cov qauv hlau; 690 - Tsawg tshaj tawm lub zog MPa; Q - quenched thiab tempered tus me nyuam mob; L - cuam tshuam lub zog kuaj ntawm -40ºC.
S690QL siab zog cov qauv hlau raug siv:
S69QL yog qhov siab heev - lub zog ntawm cov qauv hlau uas, thaum siv los hloov cov txheej txheem steel, tuaj yeem ua rau muaj peev xwm nce ntxiv - cov kabmob muaj peev xwm thiab txo qhov hnyav ntawm cov qauv. S690QL siab tensile steel ntawv siv suav nrog cov khoom siv hauv av, cov tsheb thauj khoom pov tseg, mobile cranes, drilling rigs, siab - cua turbines thiab txuas hniav.
