Характеристики:
LKE-9015-B92H4 is is designed to weld martensitic B9 (P92) alloyed steel: 9Cr steel to weld equivalent ‘type 92’ steels modified with tungsten, vanadium, niobium, nitrogen, and a small addition of boron to give improved long term creep properties
Приложения:
It is suitable for welding of Headers, Main steam piping, Turbine castings and Power generating plants
Примечания по использованию:
1.Preheat at 80°C is sometime required according to base metal or its thickness.
2.Do not exceed the range of recommended because over heat input might decrease the impact value.
3.Keep the arc as short as possible.
4.Take the back-step method at the arc starting to prevent blowholes.
