Raws li tus kws tshaj lij EN tus qauv siab- lub zog steel xa khoom nrog 20+ kev paub txog kev xa tawm, GNEE STEEL cov khoom lag luam tag nrho - loj S690QL daim hlau ua raws li EN 10025-6, tag nrho sib npaug rau DILLIMAX 690, WELDOX 700, NAXTRA 70.

 

 

High yield zog

S690QL daim hlaumuaj yam tsawg yield zog ntawm690 MPa ua, uas ua rau lawv incredibly muaj zog & ruaj. Lub zog no yog ua tiav los ntawm quenching thiab tempering uas hardens cov hlau.

 

Zoo heev toughness

Lub toughness ntawm lubS690QL phajyog qhov zoo heev, uas txhais tau hais tias nws tuaj yeem tiv taus qhov cuam tshuam thiab tiv thaiv tawg. Qhov no ua rau lawv zoo tagnrho rau kev siv hnyav - daim ntawv thov lub luag haujlwm uas qhov ua haujlwm ntev yog qhov tseem ceeb.

 

Zoo weldability

Txawm tias lawv lub zog siab & toughness, cov phaj no kuj yooj yim rau vuam. Qhov no ua rau lawv zoo tagnrho rau kev tsim kho thiab lwm yam kev lag luam uas yuav tsum tau vuam.

 

Corrosion Resistance

Lawv muaj corrosion kuj zoo, ua rau lawv haum rau siv nyob rau hauv hnyav ib puag ncig los yog daim ntaub ntawv uas lawv yuav raug rau ya raws los yog tshuaj.

 

 

S690QL Steel Phaj muaj ntau yam kev siv hauv ntau yam lag luam, suav nrog:

 

1.S690QL Hlau Rau Kev Tsim Kho Machinery.

FAQ:

Dab tsi yog qib S690QL khoom?

S690QL (Cov Khoom Naj Npawb 1.8928) yog qhov siab - tawm los, quenched thiab tempered structural steel ua raws li EN 10025-6 tus qauv. Nws tau lees tias qhov tsawg kawg nkaus tawm lub zog ntawm 690 MPa, tso cai rau kev sib zog, kev them nyiaj siab zoo xws li mobile cranes, cov khoom siv mining, thiab txuas hniav.

 

Qhov txawv ntawm A514 thiab S690QL yog dab tsi?

ASTM A514 yog lub zog siab qis alloy steel. Nws yog tsim los rau kev siv lub luag haujlwm hnyav S690QL yog quenched thiab tempered siab zog uas tsis muaj alloy steel uas muaj weldability zoo thiab ductility.

 

Dab tsi yog kev siv lub zog siab S690 steel hauv kev tsim kho?

Lub zog siab S690 steels muaj lub zog zoo heev -rau - tus kheej - qhov hnyav piv, thiab lawv muaj txiaj ntsig zoo los siv rau hauv cov qauv hnyav hnyav. Cov ntawv thov ib txwm muaj xws li pawg thiab kab hauv tsev thiab txhawb cov tswv cuab hauv cov choj.

 

Qhov txawv ntawm S700MC thiab S690QL yog dab tsi?

S700MC thiab S690QL yog ob qho tib si siab -lub zog steels tab sis ua haujlwm ntau lub hom phiaj. S700MC yog ib qho thermo-khoov hlau kho kom zoo rau kev sib sau txias thiab lub teeb yuag, qhov S690QL yog quenched thiab tempered, muab superior cuam tshuam toughness thiab durability nyob rau hauv hnyav los yog dynamic loads.

 

Dab tsi yog qhov txawv ntawm S890QL thiab S690QL?

Dab tsi yog qhov txawv ntawm S690QL thiab S890QL? Qhov sib txawv tseem ceeb yog lub zog tawm los - 690 MPa vs 890 MPa. S890QL muaj zog dua thiab sib dua, tab sis S690QL yooj yim dua rau vuam thiab raug nqi ntau dua - zoo.
