Weld Star – ER 317L Stainless TIG Wire (3.2mm) 5kg

Features and Applications

Austenitic stainless steel wire used for welding alloys of a similar chemical composition.

Ideal for severely corrosive environments where crevice and pitting corrosion are of concern.

Low carbon content reduces the possibilities of intergranular carbide precipitation.

Not suitable for structural service above 400?C or for cryogenic applications.

Weld deposit is similar to 316L with high molybdenum content for increased corrosion resistance.

Typically used in the chemical and petrochemical industries, marine environments, papermaking and food processing industries etc.
