Description

Rutile all position flux cored wire for 316 stabilised stainless steel
Austenitic rutile flux cored wire for welding and cladding 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. These consumables are used to weld Ti or Nb stabilized grades of Mo bearing austenitic stainless-steel is also used for depositing corrosion resistance overlays and valve seat inlays on medium carbon alloy steel.

Description

Application

These consumables are formulated for welding molybdenum-bearing austenitic stainless steels stabilized with titanium or niobium. Alternatively, they can be utilized for unstabilized grades like 316/316L. However, it is not advisable for structural service exceeding approximately 400°C or for applications in cryogenic conditions. Such filler metals are versatile, finding application in depositing corrosion-resistant overlays and valve seat inlays on medium-carbon alloy steels. Typically, they are supplied with a ferrite content ranging from 3-14FN. Operating guidelines include no preheating requirement and a recommended maximum interpass temperature of 250°C.

Alloy Type

Nb stabilized, Mo-bearing stainless steel.

Microstructure

Austenite with 3-14FN (3-12% ferrite), typically 10FN.
