ER70S2 yog hlau MIG & TiG zoo tshaj plaws rau kev vuam rau txhua qib ntawm cov hlau tsis hnyav thiab cov hlau carbon, tsim cov vuam zoo nrog qhov porosity tsawg kawg nkaus. Nws yog hlau triple deoxidized (Zirconium, Titanium, thiab Aluminium) ua rau nws yog qhov kev xaiv zoo heev rau kev vuam hla xeb thiab qhov ntsuas zeb. Tsis tas yuav muaj flux nrog cov khoom no.
COV NTAWV THOV IB TXWM:
cov kav dej thiab cov rigs drilling offshore, cov hlau ua haujlwm
