Qhov tseem ceeb rau hnyav- lub luag haujlwm mining tsheb thauj khoom (tshaj 100-tuj muaj peev xwm), excavators, pob tseg tsheb lub cev, thiab thee mine hydraulic txhawb nqa.
Tub rog Engineering:
Siv nyob rau hauv kev tsim kho ntawm armored tsheb, naval nkoj cov qauv, thiab riam phom systems (xws li, missile lug thiab phom phom) vim nws durability nyob rau hauv siab - kev nyuaj siab ib puag ncig.
Civil Engineering & Infrastructure:
Siv rau hauv siab- cov tsev nce siab, tsim choj choj, thiab cov nroj tsuag loj - nplai. Nws yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig rau cov qauv hauv cov huab cua txias lossis hnyav, xws li cov chaw ua haujlwm sab nrauv, qhov uas nws tuav cov kev cuam tshuam hnyav mus txog -40 degree.
Zog Sector:
Siv nyob rau hauv fabrication ntawm cua turbine yees, penstocks (dej intake pipes), thiab unfired siab hlab ntsha.
Thov ib tug kws tshaj lij hais rau S960QL los ntawm GNEE Steel.
S960QL yog dab tsi?
S960QL yog qhov siab -lub zog quenched thiab tempered structural steel qib teev nyob rau hauv European qauv. Nws yog lub npe hu rau nws lub zog muaj zog heev ua ke nrog zoo toughness, txawm nyob rau hauv qis kub, ua rau nws haum rau hnyav loaded qauv uas qhov hnyav txo kuj yog ib qho tseem ceeb.
Lub npe "S960QL" txhais li cas?
Hauv kev tsim "S960QL", tsab ntawv S sawv cev rau cov qauv hlau, tus lej qhia txog qhov tsawg kawg nkaus lub zog muaj zog, Q txhais tau tias quenched thiab tempered, thiab L qhia txog kev txhim kho toughness ntawm qis dua piv rau cov qib pib.
Cov qauv dab tsi npog S960QL?
S960QL yog them los ntawm European tus qauv rau siab- lub zog steels, tshwj xeeb tshaj yog ib feem cuam tshuam nrog quenched thiab tempered fine-grained steels. Cov txheej txheem no qhia txog cov txheej txheem kev xa khoom, suav nrog cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov kev xeem yuav tsum tau ua.
Dab tsi yog cov khoom siv kho tshuab ntawm S960QL?
