Plate has a preferable resistance to molten zinc corrosion, but low cross-intensity, the most all at about 300MPa, the zinc pot made easily becomes
Shape, impact uses and there is bigger potential safety hazard, then needing to seek superior technique measure further to eliminate above-mentioned fraud
End, as Chinese patent CN01128476.5 discloses a kind of Large Heat Input Welding high-toughness steel for resisting corrosion of molten zinc and producer thereof
Method, uses the controlled rolling condition of delivery, utilizes the composite oxides of Ti to obtain anti-large-line energy (>=50kJ/cm) welding performance,
Nb, V microalloying improves intensity, adds the precious alloys such as Cu, Ni, B, RE and improves resisting zinc liquid corrosion performance, though this method energy
Taking into account resistance to molten zinc corrosion and high-strength tenacity, but manufacturing cost is too high, wlding is difficult to coupling, answers so rare to market widely
With.
