GETIG 308H

SPECIFICATIONS :AWS/SFA 5.9 ER308H BS2901-93 308S98 DIN 8556-86 SGX5CrNi 199 prEN 12072-95 W19.9H

CHARACTERISTICS :

Getig 308H deposits a 20% Cr / 10% Ni austenitic stainles weld metal with controlled carbon content (0.04 % - 0.08 %). It is designed to weld similar composition stainless steels used for their creep strength and oxidation resistance at temperatures upto 800° C.

APPLICATIONS :

For welding ASTM A304/A304H steel, 321H and 347H stainless steels CF10, CF8. Widely used in petrochemical industry for fabrication of cyclones, transfer lines in catalytic crackers operating in the range 450 – 815°C.

SHIELDING GAS : Pure Argon 99.99% 6-12 l/min.

FERRITE CONTENT IN THE WELD METAL : 3 – 9 FN.

WELDING CURRENT : DC ( - )

CORROSION RESISTANCE : Good resistance to general and intergranular corrosion. Also good resistance to oxidising acids and cold reducing acids.
