ASTM A671 GR CC60 khoom yog dab tsi?
ASTM A671 GR CC60 yog qib ntawm electrofusion welded (EFW) steel yeeb nkab tsim raws li tus qauv ASTM A671, tshwj xeeb tsim los siv rau hauv qis - kub thiab siab - qhov chaw siab.
Kev tsim khoom
Electrofusion Vuam (EFW): CC60 steel kav yog tsim los siv cov txheej txheem electrofusion vuam, qhov twg cov hluav taws xob tam sim no melts cov npoo ntawm cov hlau phaj los tsim cov vuam. Cov txheej txheem no ua kom zoo thiab lub zog ntawm vuam, ua rau cov khoom sib xws thoob plaws hauv cov yeeb nkab.
Kev kho cua sov: Txhawm rau ua kom zoo dua cov khoom siv kho tshuab thiab qis -kub toughness ntawm CC60, cov kav hlau steel yuav xav tau kev kho cua sov thaum tsim khoom, xws li normalizing thiab tempering.

ASTM A671 GR CC60 steel kav feem ntau yog siv rau kev thauj mus los thiab khaws cia hauv qhov chaw cryogenic.
Cov ntawv thov ib txwm muaj xws li:
- Liquefied Natural Gas (LNG) Kev Thauj Mus Los: Vim nws cov tawv nqaij cryogenic, nws tsim nyog rau LNG cov kav dej ua haujlwm ntawm qhov kub tsis tshua muaj siab.
- Polar Roj thiab Gas Extraction: Ua tau raws li qhov xav tau siab rau cov khoom siv hauv cov kav dej hauv cov cheeb tsam txias.
- Industrial Gas Cia thiab Tsheb thauj mus los: Siv rau cov kav dej thauj cov khoom siv cryogenic xws li kua nitrogen thiab kua oxygen.
