KN-718G
Type of coating: Iron powder low hydrogen type
A low hydrogen coated electrode for 490N/mm2 grade steel for low temperature resistance
It is ideal for welding in low temperature resistant steel of LPG storage tanks.( ASTM A537C1,JIS G3126 and SLA325A)

Classification


Application and Features 

• A low hydrogen coated electrode for 490N/mm2 grade steel for low temperature resistance
• Weld metal contains 1.5%Ni with good conditions of CVN obtained at -45°C
• It is suitable for Flat and H-Fillet welding
• It is ideal for welding in low temperature resistant steel of LPG storage tanks.( ASTM A537C1,JIS G3126 and SLA325A)

Welding Position


Welding Instruction

1. Clean up the contaminations on the steel. Keep arc as short as possible
2. Dry the electrodes 350~400°C in 60 minutes before welding
3. Excellent strike and re-strike capabilities with the back step method. (Please refer to Appendix A)
4. Please note that over welding heat input causes the poor conditions in CVN

Application
- It is ideal for welding in low temperature resistant steel of LPG storage tanks.( ASTM A537C1,JIS G3126 and SLA325A)
