GETIG 317L

Classification : AWS/SFA 5.9 : ER 317L

CHARACTERISTICS :

A stainless steel tig rod intended for welding of low carbon, molybdenum alloyed, acid resisting austenitic stainless steel of similar composition (317/317L). The deposited weld metal is of X-ray quality. The higher molybdenuem content provides better resistance to both acid corrosion and pitting corrosion compared to 316L stainless steel grade.

CORROSION RESISTANCE:

Good resistance to general and intergranular corrosion in most inorganic and organic acids e.g. sulphurous and sulphuric acids. Good resistance to chloride pitting resistance.

SHIELDING GAS :

Pure Argon : 99.99% -> 8-16l/min + back purging
