OERLIKON expertise : INERTFIL 308L

INERTFIL 308L is used for welding of 304 and 304L grade stainless steel. The weld metal provides good corrosion resistance properties to intergranular attack from a range of liquid media at service temperatures up to 300°C. It is used for a wide range of applications including pipework and plate fabrication, vessel production etc. Batch with controlled low ferrite number is available for cryogenic applications. The low carbon content reduces the propensity to intergranular carbide precipitation, which increases the resistance to intergranular corrosion without the use of stabilizers. Stainless steel wire for welding AISI 304 and 308 steels. Excellent mechanical strength and corrosion resistance.

Available in BS300.
Diameter of 1,6.
