  • AUSTENITIC STAINLESS STEELS
308L

Description

Rutile all position flux cored wire
Austenitic flux cored wire for welding and cladding 18/8 stainless steels in all positions thanks to the fast-freezing slag. It offers excellent weldability, easy handling and slag control in all positions resulting in high productivity with outstanding welding performance. Self-releasing slag requiring less cleaning and pickling, very low spatter formation and increased travel speeds allow to obtain noticeable savings in time and costs. Main applications include food industries, pharmaceutical equipment and general fabrication. Typical service temperatures are -100°C to 400°C.

Description

Application

Engineered for welding 18Cr/8Ni stainless steels, encompassing 301, 302, 303, nitrogen-bearing 304LN, and titanium-stabilized 321, these welding consumables offer versatile performance. They perform well in service temperatures ranging from -100°C to about 400°C, making them suitable for applications in food, brewery, pharmaceutical equipment, architectural and general fabrication, as well as nuclear engineering. It's important to note that these consumables, specifically 308L, are not recommended for elevated temperature structural applications involving 304/304H; refer to 308H for such applications. For cryogenic use at -196°C, consult 308LCF. No preheating is required, and the recommended maximum interpass temperature is 250°C, with no post-weld heat treatment necessary.

Alloy Type

308L austenitic stainless steels for joining 304L base materials.

Microstructure

Austenite with a controlled level of ferrite, normally in the range 3-12FN depending on the application.
