Why choose this cored wire?
-
Designed for 904L stainless steel
This wire is formulated to perfectly match the chemical composition of 904L (an alloy rich in nickel, molybdenum and copper), guaranteeing optimum resistance to corrosion after welding. -
Higher productivity than TIG
The flux-cored wire enables a much higher deposition speed, which is particularly useful in flat welding (PA position), where its efficiency can be fully exploited. -
Good mechanical and metallurgical properties
The deposited metal offers high resistance to intergranular corrosion, crevice corrosion and pitting – indispensable performances in the chemical, offshore and pharmaceutical industries. -
Reduced hydrogen-related defects
The wire powder, which is often basic, contributes to a low level of diffusible hydrogen, reducing the risk of cold cracking in this sensitive material. -
Optimized use in flat position
Flat welding maximizes the stability of the molten pool, produces a uniform deposit and makes it easier to remove slag (if any), thus improving efficiency and bead quality.
