Описание
Характеристики:
LKE-2594 is a designed to weld super duplex stainless steels. With excellent pitting corrosion resistance, stress corrosion resistance and crack resistance. Properties of the weld metal match those of the parent metal, offering high tensile strength and toughness as well as an excellent resistance to stress corrosion cracking and localized corrosion in chloride containing environments.
Приложения:
It is suitable for welding of chemical equipment, heat exchanger and pipes. The operating temperature range is –50ºC to 220ºC.
Примечания по использованию:
1.Dry the electrodes at 250-300°C for 60 minutes and keep at 100-150°C before use.
2.Use lower currents and keep the arc as short as possible.
