GETIG 317

SPECIFICATIONS : AWS/SFA 5.9 : ER 317

CORROSION RESISTANCE :

Good resistance to general and intergranular corrosion in Most inorganic and organic acids

CHARACTERISTICS :

A stainless steel tig rod intended for welding of low carbon, molybdenum alloyed, acid resisting austenitic stainless steel of similar composition (317). 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.

TYPICAL USES :

For welding ASTM/ASME 317 CF8M, DIN 1.4404/ 1.4401, 1.4403, 1.4436.Fabrication of stainless steel structures and assemblies such as plate, pipe work, vessels, tanks, forgings and castings, in the chemical power and pharmaceutical industries, food, drink and paper processing plant.
e.g.sulphurous and sulphuric acids. Good resistance to chloride pitting resistance.

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