Q490R Tempered Container Plate, Q490R cov khoom siv dav siv hauv kev tsim cov khoom siv rau cov tsev siab, xws li kab teeb thiab kab. Nws lub zog siab tuaj yeem tiv taus ntau lub siab thiab qhov hnyav, thaum corrosion kuj ua kom nws lub neej ua haujlwm ntev.
"Q": qhia lub zog ntawm cov hlau phaj "yield" pib
"490": qhia tias qhov kev txwv qis ntawm cov khoom siv zog ntawm cov phaj steel tsis tsawg dua 490MPa.
R - siab lub nkoj "Rong" ntawm thawj tsab ntawv ntawm hanyu pinyin.
Q490R cov khoom zoo yog feem ntau cuam tshuam hauv cov hauv qab no:
1. lub zog siab: Q490R cov khoom muaj lub zog muaj zog thiab lub zog tensile, muaj peev xwm tiv taus siab dua thiab thauj khoom, muab kev nyab xeeb thiab txhim khu kev ntseeg siv. 2. Kev ua haujlwm txias ua haujlwm zoo: Q490R cov khoom muaj kev ua haujlwm txias txias.
2. Kev ua haujlwm txias txias zoo: Q490R cov khoom muaj cov yas zoo thiab ductility, tuaj yeem ua rau ntau yam duab thiab qhov ntau thiab tsawg los ntawm kev ua haujlwm txias kom tau raws li qhov xav tau ntawm engineering sib txawv.
3. Kev ua haujlwm vuam zoo heev: Q490R cov khoom muaj kev ntseeg tau zoo vuam thiab tuaj yeem txuas tau los ntawm ntau txoj kev vuam, ua kom yooj yim rau kev tsim thiab nruab.
4. Muaj zog corrosion kuj: Q490R cov khoom tau raug tshwj xeeb alloyed thiab nto kho kom zoo corrosion kuj, thiab tuaj yeem ua haujlwm hnyav ua haujlwm ntev yam tsis muaj kev puas tsuaj.
