S690Q, S890Q, thiab S960Q yog siab -lub zog steels (HSS) txhais los ntawm lawv qhov tsawg kawg nkaus yield zog (690, 890, 960 MPa), nrog 1.8931, 1.8940, thiab 1.8941 yog lawv cov khoom siv European EN. Qhov sib txawv tseem ceeb yog lub zog: S960Q yog qhov muaj zog tshaj, S690Q yog qhov muaj zog tsawg, thiab tag nrho cov khoom muaj zog zoo (Q pab pawg rau -20 degree), ua rau lawv zoo tagnrho rau cov tshuab hnyav, cranes, thiab txuas hniav, nrog cov lej siab dua qhia tias muaj peev xwm thauj khoom ntau dua tab sis feem ntau yuav tsum tau ceev faj ntau dua fabrication.
Core Difference Analysis
Raws li qib qib nce, lub zog tawm los nce siab (690 → 890 → 960 MPa), thaum elongation thiab cuam tshuam toughness yuav txo qis, qhia txog kev lag luam - tawm ntawm lub zog thiab plasticity.
Chemical Composition Yam ntxwv
- S690Q: Cov pa roj carbon tsawg (tsawg dua lossis sib npaug li 0.20%) thiab cov hlau tsis tshua muaj, nrog cov ntsiab lus qis Cr / Ni / Mo, hais txog qhov zoo weldability thiab formability.
- S890Q: Nruab nrab alloying, nrog tsim nyog nce Mn / Cr / Mo kom sib npaug zog thiab txheej txheem qhov rais.
- S960Q: Siab dua Ni/Cr/Mo thiab microalloying ntsiab (Nb/V/Ti) kom paub meej ultra-siab zog thiab hardenability.
Txheej txheem thiab Weldability
- S690Q: Qhov zoo tshaj plaws weldability, yuav tsum tau preheating kub ntawm 50-100 degree, haum rau complex qauv thiab tuab phaj vuam.
- S890Q: Yuav tsum muaj tsawg- cov khoom siv hydrogen welding thiab preheating (100-150 degree), nrog tswj cov cua sov input kom tsis txhob softening ntawm tshav kub- thaj tsam cuam tshuam.
- S960Q: Feem ntau xav tau weldability, yuav tsum tau nruj preheating (150-200 degree), qis- hydrogen txheej txheem, thiab post-weld tshav kub kho, nrog ntau dua springback thaum tsim.
Tej yam kev thov Scenarios
- S690Q: Engineering machinery booms, txuas hniav, tsheb chassis, nrhiav kev sib npaug ntawm lub zog thiab tus nqi.
- S890Q: Loj-tonnage crane booms, cov khoom siv mining, siab - cov nkoj siab, tsom rau kev tsim qauv hnyav thiab muaj peev xwm thauj khoom siab.
- S960Q: Ultra-loj engineering machinery, tseem ceeb load- bearing Cheebtsam ntawm high-kawg cov cuab yeej, yuav tsum tau hnyav heev txo thiab cov qauv compactness.
