Tsawg-Tsub Toughness: S690QL1 steel, tshwj xeeb, yog tsim los tswj nws lub zog siab txawm tias qhov kub thiab txias, ua rau nws tsim nyog rau kev siv hauv Arctic lossis qhov chaw txias.

Fine-Ntau yam qauv: Cov qhab nia no feem ntau muaj qhov zoo -grained microstructure, uas txhim kho lawv cov khoom siv kho tshuab, suav nrog kev cuam tshuam rau qhov hnyav thiab qaug zog.

Weldability: Txawm tias lawv lub zog siab, S690Q / QL / QL1 steel qib tau paub txog lawv qhov zoo weldability. Txawm li cas los xij, kev ceev faj tshwj xeeb thiab cov txheej txheem vuam yuav tsum tau ua kom ntseeg tau siab -cov pob qij txha zoo.

Ntau yam: Cov qib steel no muaj ntau yam thiab pom cov ntawv thov hauv ntau yam kev lag luam, suav nrog kev tsim kho, tsuas, thiab kev tsim cov tshuab hnyav. Lawv siv rau cov khoom siv tseem ceeb, xws li crane booms, cov hlab ntsha siab, thiab cov qauv kev txhawb nqa.

Ua raws li Cov QauvS690Q / QL / QL1 steel ua raws li European cov qauv (EN 10025-6), ua kom ntseeg tau zoo thiab ua haujlwm tau zoo hauv kev thov cov qauv siv.

Quality Assurance: Cov neeg tsim khoom ntawm cov qib steel no ua raws li cov txheej txheem tswj xyuas kom muaj kev ntseeg siab thiab kev nyab xeeb ntawm cov khoom, tshwj xeeb tshaj yog nyob rau hauv qhov tseem ceeb ntawm cov khoom siv thauj khoom -cov kabmob.

S690Qfeem ntau yog siv rau hauv cov txuas hniav, cov qauv tsim, cranes, thiab cov tshuab hnyav hnyav uas yuav tsum muaj lub zog siab tab sis ib puag ncig tsis txias heev.

S690 qwNws yog qhov zoo dua rau cov qauv hauv ntug dej hiav txwv, cov cua ntsawj ntshab, Arctic engineering, thiab lwm yam qis - qhov kub thiab txias qhov chaw uas tiv thaiv kev tawg tawg yog qhov tseem ceeb.

Ob yam khoom pub rauqhov hnyav txo hauv cov qauvvim lawv lub zog siab -rau- qhov hnyav piv, txhim kho kev ua tau zoo thiab txo cov nqi khoom.

S690Q thiab S690QL sib koom tib lub zog tab sis txawv ntawm lawv qhov hnyav thiab qhov kub thiab txias. Yog tias koj qhov project ua haujlwm hauv huab cua ib txwm lossis me me,S690Qmuab cov nqi zoo heev thiab kev siv zog ua haujlwm.
