3. Kev Thauj Khoom Tshwj Xeeb & Kev Tiv Thaiv
Tub Rog Lub Tsheb Chassis & Armor Support Structures: Rau lub teeb yuag, siab -mobility tactical thiab kev tiv thaiv tsheb uas yuav tsum tau ua kom tawg.
Aerospace Ground Support Equipment: Xws li hnyav- lub luag haujlwm dav hlau towbars thiab thauj khoom platforms.
Siab-Kev Ua Haujlwm Sib Tw Tsheb Chassis & Roll Cages (hauv sab saum toj-tier motorsports).
4. Advanced Engineering Structures
Offshore Mooring & Lifting Cheebtsam: Cov kev sib txuas tseem ceeb, pins, thiab cov khoom sib txuas hauv qhov sib sib zog nqus -dej roj & roj platforms thiab marine installations.
Tshwj xeeb Choj Cheebtsam: Rau cov khoom txav tau (piv txwv li, nqa lossis viav vias ntu) hauv cov cheeb tsam txias uas txo qhov hnyav yog qhov tseem ceeb rau cov tshuab tshuab.
Siab-Qhov Kev Nyuaj Siab hauv Offshore Cua Turbines: Xws li cov flanges tshwj xeeb lossis cov khoom hloov pauv hauv qhov xav tau ib puag ncig.
Vim li cas S890QL thiaj xaiv:
Qhov hnyav tshaj plaws: Nws 890 MPa yield zog tso cai rau nyias, sib zog seem thaum tuav lub peev xwm thauj khoom, tseem ceeb heev rau cov khoom siv txawb uas hnyav txhais ncaj qha rau hauv kev ua haujlwm (payload, ncav cuag, roj efficiency).
Txias-Kev nyab xeeb muaj peev xwm: "QL" tsim kom ntseeg tau tias muaj kev cuam tshuam hnyav ntawm -40 degree, ua rau nws haum rau Arctic, qhov siab siab, lossis lub caij ntuj no.
Space Efficiency: Ua kom muaj kev sib haum xeeb, siab dua - muaj peev xwm tsim.
