KN-816G

Type of coating: Low hydrogen type。
It is suitable for welding 540N/mm2。
It is ideal for welding low temperature steel used in LPG storage tanks。

It is suitable for welding 540N/mm2 grade steel for low temperature resistance.
It provides good weldability, stable arc and easy slag removal.
Weld metal contains 1.5%Ni and has good impact properties at -45°C.
It is ideal for welding low temperature steel used in LPG storage tanks, such as ASTM A537C1,JIS G3126 and SLA325A.

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
