KN-816C1

Type of coating: Low hydrogen type。
It is suitable for welding 540N/mm2。
Ideal for welding low temperature machine。

It is suitable for welding 540N/mm grade steel for low temperature resistance.
Good weldability and X-ray quality welds.
Weld metal contains 2.5%Ni and good impact properties at -60°C.
Ideal for welding low temperature machine, Al-killed steel for low temperature and 2.5%Ni steel, such as JIS G3127 and SL2N 255.

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.
