Qhov zoo ntawm nws yog dab tsi?
Qhov zoo ntawm A709 Qib HPS100W
1. muaj zog heev
Muab 100 ksi (690 MPa) yield zog tsawg kawg nkaus.
Tso cai sib dua, slimmer girders thiab txo qhov hnyav hlau.
2. Zoo heev toughness
Tsim los tswj kom muaj kev puas siab puas ntsws toughness, txawm tias qhov kub thiab txias.
Txhim kho kev nyab xeeb thiab kev cia siab rau ntev - txuas txuas.
3. Txhim kho weldability
Tsawg carbon thiab optimized alloying nce weld zoo.
Txo cov kev xav tau preheat piv nrog cov pa Qib 100W.
4. Huab cua tsis kam
Muaj Cu, Cr, thiab Ni rau atmospheric corrosion kuj.
Nws tuaj yeem siv tsis tau pleev xim, txo qhov ntev - cov nqi tu.
A709 Qib HPS100W siv rau dab tsi?
A709 Qib HPS100W yog siv rau siab - kev ua haujlwm choj cov qauv uas yuav tsum tau muaj zog thiab kav ntev. Nws muab lub zog tawm tsawg kawg nkaus ntawm 100 ksi (690 MPa) thiab lub zog tensile ntawm li 110–130 ksi (760–895 MPa), tso cai sib dua thiab ntev dua -span girders. Nws cov huab cua chemistry, feem ntau suav nrog 0.25-0.50% Cu, 0.40-0.70% Cr, thiab 0.25-0.75% Ni, txhim kho corrosion kuj. Vim hais tias ntawm cov khoom no, nws yog dav siv nyob rau hauv phaj girders, lub thawv girders, ntev - ncua txuas hniav, thiab hnyav - load structural Cheebtsam.
