Description
E 308L – 16 Electrode
MARUTHI E308L-16 is an extra Low carbon rutile coated electrode giving a filler metal of the Cr-Ni type. Has perfect quality smooth weld beads which are highly resistant to acids, intergranular corrosion at operating temp up to 350 ̊C & to oxidation up to 800 ̊C Easy slug removal and stable arc. Ideal for welding of steels corresponding to AISI 301,302,304,304L, 308 & 308L.
Applications:
- Autsenitic titanium oxide coated electrode of ELC quality for welded joints and surfacing on stabilised and unstabilised, corrosion-resistant and cold-tough 18/8 Cr-Ni steels. Welded joints on ferritic chromium steels (up to max. 18% Cr), only for root and intermediate runs if there is a risk of corrosion due to sulphur attack.
Characteristics:
- Austenitic weld metal with 5 – 9% ferrite content. Suitable for welding parts subjected to operating temperatures of up to +350°C. Non-scaling properties up to 800°C in air and in oxidizing combustion gases.
Current mode: DCEP / AC
