Tsawg- ntsuas kub yog qhov tseem ceeb vim tias nws ua kom cov hlau ua haujlwmresiliencethiab muaj peev xwmua kom muaj kev nyab xeeb hauv cov xwm txheej txias. ASTM A516 Qib 65 yog qhov cuam tshuam - kuaj rau-29 degree, xyuas kom nws tsis muaj kev paubbrittle puasnyob rau hauv kev ntxhov siab ntawm qhov kub thiab txias. Qhov no tseem ceeb heev rausiab hlab ntsha thiab tankssiv nyob rau hauv cheeb tsam nroghuab cua txiaslos yog rau kev lag luam uas muaj qhov kub thiab txias hloov pauv, xws liroj thiab roj lossis tshuaj ua haujlwm.
Cov txheej txheem tsim dab tsi haum rau ASTM A516 Qib 65?
ASTM A516 Qib 65 yog tsim raudov, khoov, thiab niasvim nwsnruab nrab lub zog thiab zoo heev ductility. Nws tuaj yeem yogtxias - tsimrau hauv ntau yam duab tsis muaj cracking, ua rau nws zoo tagnrho raucov hlab ntsha, boilers, thiab cia tanks. Txawm li cas los xij, raunruj radii los yog tuab daim hlau, Kev kho cua sovtej zaum yuav xav tau kev tshaj tawm - ua kom txo qis kev ntxhov siab thiab ua kom ntseeg taukhoom stabilitynyob rau hauv siab los yog kub.
