EN10025 yog cov qauv tsim los ntawm European Committee for Standardization (CEN) rau "tsis yog- alloy thiab nplua- cov khoom siv hlau", uas tau muab faib ua ntau yam los tswj cov qauv hlau nrog cov khoom sib txawv. Ntawm lawv:
EN10025-6 tshwj xeeb yog hais txog "High yield zog structural steels nyob rau hauv quenched thiab tempered mob." Nws siv rau cov qib high-strength steel nrog lub zog tawm los Ntau dua lossis sib npaug ntawm 690 MPa, hais txog cov khoom siv lub zog siab, siab tawv, thiab ua haujlwm tau zoo tom qab quenching thiab tempering (Q&T) kev kho cua sov.
Lub npe qib S960Q muab cov ntaub ntawv tshwj xeeb txog cov hlau cov khoom siv kho tshuab:
S (Structural Steel): Cov lus Askiv luv rau cov qauv hlau, qhia nws siv rau kev thauj khoom -cov kabmob.
960: Sawv cev rau qhov tsawg kawg nkaus lub zog ntawm 960 MPa (megapascals), ib qho tseem ceeb metric ntsuas cov khoom tiv thaiv rau deformation. Nws poob rau hauv qeb ntawm "ultra- siab- lub zog steel" (yield zog> 690 MPa tsim nyog raws li ultra- siab zog).
Q (Quenched thiab Tempered): Qhia tau tias cov khoom tau dhau los "quenching + tempering" kev kho cua sov, txheej txheem tseem ceeb kom ua tiav qhov sib npaug ntawm lub zog siab thiab toughness -quenching txhim kho hardness thiab lub zog, thaum tempering txo brittleness thiab xyuas kom muaj zog.

Q: Cov nqe lus shipping yog dab tsi?
A: Peb lees txais FOB, CIF, CFR thiab lwm yam kev xa khoom thoob ntiaj teb. Chaw nres nkoj ntawm kev thauj khoom tuaj yeem teev raws li cov neeg siv khoom xav tau.
Q: Qhov txawv ntawm S960Q thiab Q355 thiab Q460 zoo li cas?
A: S960Q muaj zog ntau dua li cov qauv hlau zoo tib yam:
Lub zog siab dua → Cov qauv sib dua, muaj zog dua - cov kabmob muaj peev xwm
Cov txheej txheem tsim khoom nruj dua → Quenching + tempering kho
Kev ua haujlwm ruaj khov dua → Muaj zog qis dua -kub toughness thiab qaug zog ua haujlwm
