KN-816C3

Type of coating: Low hydrogen type
It is suitable for welding 540N/mm2 grade steel for low temperature resistance.

It is suitable for welding 540N/mm2 grade steel for low temperature resistance.
It provides superior weldability and X-ray quality welds.
Weld metal contains 1.1%Ni-0.25%Mo and good impact properties at -40°C.
It is ideal for welding in LNG storage tanks or 1%Ni steel for low temperature resistance

Clean up the contaminations on the steel.
Dry the electrodes at 350~400°C for 60 minutes before welding.
Keep arc as short as possible. Take the back step method to prevent porosity at arc start and re-start. (Please refer to Appendix A)
High heat input will lower the impact value. Please carefully select the welding current.
The preheat temperature for thick plate is 50~100°C.

It is ideal for welding in LNG storage tanks or 1%Ni steel for low temperature resistance
