S690Q Cov Qauv Hlau Phaj vs S690QL Alloy Steel Phaj

Qhov txawv tseem ceeb yog qhov ntawd S690 qwmuaj superior qis-kub los cuam tshuam toughnessvim nws Charpy V-qhov ntsuas qhov cuam tshuam tau ua tiav ntawm –40℃𝐶, thaumS690Q raug kuaj ntawm -20℃𝐶. Ob leeg yog siab -lub zog quenched thiab tempered steels nrog qhov tsawg kawg nkaus yield zog ntawm 690 MPa, tab sis S690QL zoo dua rau cov huab cua txias lossis cov ntawv thov uas xav tau kev ua haujlwm hauv sub-zero ib puag ncig.

Ob leeg S690Q thiab S690QL muab qhov tsawg kawg nkaus yield zog ntawm690 MPa uathiab lub zog tensile nruab nrab770-940 MPa, nyob ntawm thickness. Qhov loj sib txawv yog nyob rau hauv lubcuam ​​tshuam toughness ntsuas kub:

• S690Qyog kuaj ntawm0 degree, xyuas kom zoo toughness nyob rau hauv ib txwm kub tej yam kev mob.
• S690 qw, ntawm qhov tod tes, yog sim ntawm-40 degree, muab superior cuam tshuam tsis kam ntawm qhov kub thiab txias.

Qhov no ua rauS690 qwtsim nyog rau cov ntawv thov nyob rau hauv cov huab cua txias los yog qhov chaw cov qauv raug cuam tshuam rau sub-zero ib puag ncig, xws li offshore platforms los yog sab qaum teb kev tsim kho tej yaam num.

Ob qib steel yog tsim los sivTMCP (Thermo-Cov txheej txheem tswj kev siv tshuab)ua raws liquenching thiab tempering. Cov txheej txheem siab heev no kho cov microstructure, ua tiav lub zog zoo thiab weldability thaum tuav lub zog.

Cov "Q" nyob rau hauv lawv lub npe hais txog tusquenched thiab temperedtxheej txheem, thaum lub "L" hauv S690QL qhiaqis- ntsuas qhov kub thiab txiasUa raws li EN 10025-6 tus qauv.

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 txhua yam.

Qhov txawv ntawm S690Q thiab S690ql yog dab tsi?

S690Q: Yam tsawg kawg nkaus toughness kuaj ntawm -20℃(30J nruab nrab). → Hom Kev Siv: Cranes nyob rau hauv huab cua sov, cov khoom siv hauv av. S690QL: Muaj ntawv pov thawj rau -40℃thiab qis dua (Ntau dua lossis sib npaug rau 40J cuam tshuam toughness). → Kev siv tseem ceeb: Arctic pipelines, offshore platforms, mining tsheb hauv Siberia.

S690ql khoom yog dab tsi?

S690QL steel yoglub zog siab, tsis tshua muaj hlau alloy qauv uas tau tsim los siv rau hauv hnyav-cov haujlwm xws li cranes, txuas hniav, thiab lwm yam qauv. Cov qib steel no tseem hu ua Quenched thiab Tempered Steel, uas yog hais txog nws cov txheej txheem kho cua sov.

Qhov sib npaug ntawm S690ql yog dab tsi?

S690ql yog cov txheej txheem siab - qib zog. ASTM En 10025 6 S690ql Sib npaug Astm yog qhovq345 ua. Cov qib qhia tau zoo tshaj plaws txias stamping thiab qis - kub khoom.

Qhov txawv ntawm S700MC thiab S690ql yog dab tsi?

S700MC Steel yog ib qho ntawm cov qauv steel phaj tsim tshwj xeeb tshaj yog rau cov ntawv thov uas yuav tsum tau muaj zog yield zog. Lawv yog siv rau ntau daim ntawv thov load bearing. Lub S690ql yog cov hlau tsis tshua muaj hlau uas muaj zog thiab tuaj nrog kev sib txuas zoo.

S690QL siv rau dab tsi?

S690QL steel phaj kuj muaj kev tiv thaiv zoo heev rau kev puas tsuaj thiab hnav, ua rau lawv zoo tagnrho rau kev siv hnyav thiab tsim kua muag. Lawv muaj peev xwm tiv taus qhov cuam tshuam thiab zawv zawg abrasion, ua rau lawv zoo tagnrho raucov cuab yeej siv, mining machinery, thiab lwm yam kev lag luam uas xav tau cov khoom siv ruaj khov thiab ruaj khov.
