Introduction：
For 490Mpa grade high tensile carbon steel .
Low S and P content minimizes weld sensitivity to hot cracking and ensures high low-temperature impact toughness.
Well weldability: stable arc, easy slag removal,neat weld bead.
Application：
Ship building
Steel Structure
Pressure Vessel
Pass the certification：
CE、JIS
